How can we use what we figured out to help us explain why juncos have different wing lengths?

What causes different traits?

susanloveland3_3 — 2024-03-14 12:43:13 UTC

How does this picture explain why siblings from the same biological parents sometimes inherit different traits?

kendallscott3 — 2025-02-19 15:44:57 UTC

Dominant traits show themselves even if just one copy of a dominant allele exists. Recessive traits are when there are two copies of a recessive allele.

chelseaschmidt1 — 2025-02-19 15:46:58 UTC

Dominant traits are traits that show if there is only one copy but recessive traits don't show unless there are two copies.

2025-02-19 15:48:23 UTC

Dominate traits are the traits that are typically/most likely passed down. They override the lesser gene. Recessive traits are the ones that might go under the radar if a dominant trait is accessible, this is why a recessive trait only shows when two alleles of the gene are present.

summerlawlor1 — 2025-02-19 15:54:54 UTC

Dominant traits can exist, even if there's only one dominant gene, while you must have two recessive genes to make a recessive trait.

2025-02-19 15:55:20 UTC

Each parent carries a different set a genes, some they don't even show physically, and when you toss their genes into a big mixing pot you get the different variations (you and your siblings)

2025-02-19 15:56:53 UTC

dominant traits are the main traits that show themselves if they are there with a recessive allele, while recessive traits don´t show unless there is no dominant allele present.

kendallscott3 — 2025-02-19 15:59:19 UTC

Biological siblings can inherit different traits because the genes from the parents that are passed on are randomized. Giving each sibling a variation of traits that can differ from one another.

2025-02-19 16:00:39 UTC

egg and sperm each contain 23 chromosomes from the mother and father, transporting it to the zygote as 46 chromosomes or 23 pairs of chromosomes.

the molecule that stores genetic information that is used to create different traits is the DNA strand

summerlawlor1 — 2025-02-19 16:01:04 UTC

Siblings from the same biological parents sometimes inherit different traits because the genes that get passed down to the offspring are randomized.

2025-02-19 16:01:09 UTC

The egg and sperm transfer the chromosomes that hold DNA used for your offspring. Once combined the zygote creates its own unique copy of the information it was given

chelseaschmidt1 — 2025-02-19 16:01:57 UTC

Egg and sperm cells transport these molecules from one generation to the next. The DNA strand stores the genetic information used to create different traits.

kendallscott3 — 2025-02-19 16:02:14 UTC

Gametes transport molecules from one generation to the next. Chromosomes store the genetic information that is used to create different traits.

summerlawlor1 — 2025-02-19 16:02:20 UTC

The cells that transport these molecules from one generation to the next are sperm and egg cells.
The molecule that stores the genetic information that is used to create different traits is the DNA.

chelseaschmidt1 — 2025-02-19 16:04:05 UTC

This picture explains why siblings from the same biological parents sometimes inherit different traits because they could receive different chromosomes from their parents causing them to get different traits than their siblings.

chelseaschmidt1 — 2025-02-19 16:05:09 UTC

This compares to how genetic information is inherited in bacteria because they use mitosis for reproduction and copy their DNA and then split it in half.

kendallscott3 — 2025-02-19 16:05:38 UTC

Bacteria splits in half to create two identical copies of itself. While DNA replicates itself to mix and match genes with the other parent.

summerlawlor1 — 2025-02-19 16:06:40 UTC

This picture compares to how genetic information is inherited in bacteria because they both split in half to create identical copies of the DNA.

2025-02-19 16:07:41 UTC

The bacteria use mitosis to exact copy their DNA then mix the split to reinforce one-half of them.

Some pigeons have smooth heads, like their wild ancestors had. But on some domestic pigeons, the feathers on the back of the head and neck stand up to form a crest.

Inherited characteristics are the products of proteins, and proteins are coded for by genes.

brooketaylor25 — 2025-02-20 16:20:25 UTC

1- The T-check is a mostly dark wing with white on the top. Check is mostly white wing with some dark splatters and bars at the bottom. The bar is when it's an all white wing with two dark lines at the bottom. Finally barless is a plain grey wing.

2- The wing pattern is controlled by 1 single gene but two alleles depending on it is dominant or recessive

3- There is 4 different alleles that influence this trait

4- Inherited DNA is a product of the proteins. These are used to determine the genes.

5- There are 10 different genotypes that result in 4 different phenotypes.

calehudson1 — 2025-02-20 16:21:37 UTC

1) there are 4 different patterns, results of genetic variations.

2) wing pattern is controlled by a single gene

3)4

4) proteins effect what genes will be dominant and recessive

5)4

Bar wings are all white besides two black stripes and a gray tip near the end of the wing. Barless wings have a gray tip but the rest of the wing is pure white. T-check wings are mostly black with white speckles and black wing tips. Check wings are mostly white with black speckles and black wing tips.
Wing patterns are controlled by a single gene. One pattern gene is inherited from each parent.
There are four different alleles that influence this trait. T-check, check, bar, and barless.
The proteins will affect whether the genes are dominant or recessive genes.

1. The different versions of these traits are recessive red or ash red.

2. There are two different genes that influence this.

3. The gene's two versions are recessive red or not recessive red, which is also called wild-type.

4. The genes affect the melanin.

5. This can result in what color the bird is.

cashcay1 — 2025-02-24 16:02:48 UTC

What we figured out helps us explain why juncos have different wing lengths because this info concludes that there are different variations and versions for wing lengths within the gene that changes the phenotype.

chelseaschmidt1 — 2025-02-24 16:04:07 UTC

Juncos have different wing lengths because of environmental factors, phenotypes, and genotypes.

2025-02-24 16:05:18 UTC

Through natural selection and advantageous traits, the city Juncos evolved to develop smaller wings since alleles and eventual phenotypes are filtered out to become their desired traits, from their environmental factors in addition to the aforementioned conditions.

2025-02-24 16:06:16 UTC

they all got different wing sizes because of where they live and what type of junco they are.

calehudson1 — 2025-02-26 15:59:34 UTC

Siblings of the same parents will inherit different traits. Do to different dominant and recessive traits. Resulting in different genetic builds. Different hair, height and other traits.

calehudson1 — 2025-02-26 16:01:35 UTC

The bacteria spits to create two copies of itself. The DNA replicates itself, matching its producers genes.

calehudson1 — 2025-02-26 16:03:09 UTC

The eggs and sperm transfer chromosomes, with DNA. Passing its traits down to the future offspring. Resulting in similar traits.

tylervaughn1 — 2025-02-26 16:03:22 UTC

this compares to how genetic information is inherited in bacteria because bacteria uses mitosis for reproduction by copying its own dna and splitting in half making a new organism.

calehudson1 — 2025-02-26 16:05:56 UTC

Dominate traits show themselves, even if there is only one dominate trait, but for the trait to be recessive there must be two recessive genes.

tylervaughn1 — 2025-02-26 16:08:19 UTC

This picture explains why siblings from the same biological parents sometimes inherit different traits because each parent carries a different kind of gene, and when you mix them together, they get separated from each other and give the kids different genes from each other or the parents
