Mendel´s Laws: Two of the principles of heredity discovered by Gregor Mendel are Law of Segregation and Law of Independent Assortment.
Polygenic Inheritance: Traits such as eye color are determined by more than one gene.
Sex-linked Traits: Hemophilia is an X linked recessive trait.]]> 2020-06-05 17:47:36 UTC https://padlet.com/mariarojasf2022/ae10ia8ti5yi5bgw/wish/613456169 Genes and Chromosomes mariarojasf2022 https://padlet.com/mariarojasf2022/ae10ia8ti5yi5bgw/wish/613568481 Sex is determined by the presence of certain chromosomes.
Gene mutations are changes in the DNA and it could beneficial or not. (For example, dimples are caused by gene mutations)
Alleles of organisms within a population change because of mutation, gene flow, or sexual reproduction.
Sex chromosome abnormalities occur as a result of chromosome mutations or problems that occur during meiosis.]]> 2020-06-05 19:10:12 UTC https://padlet.com/mariarojasf2022/ae10ia8ti5yi5bgw/wish/613568481 Reproduction mariarojasf2022 https://padlet.com/mariarojasf2022/ae10ia8ti5yi5bgw/wish/613568935 This is a process by wich two individuals produce offspring with genetic traits from both parents.

Gametes are haploid and reproductive cells that unite at fertilization to form a cell called zygote. Haploid cells contains one complete set of chromosomes.
Fertilization is the union of two sex cells wich results in the production of offspring with a mix of inherited genes.

Parthenogenesis is a type of asexual reproduction that does not require the fertilization of a female egg cell.]]> 2020-06-05 19:10:29 UTC https://padlet.com/mariarojasf2022/ae10ia8ti5yi5bgw/wish/613568935 Mitosis and Meiosis mariarojasf2022 https://padlet.com/mariarojasf2022/ae10ia8ti5yi5bgw/wish/613569626 DNA replication is the process of copying the DNA within our cells. During cell cycle cells grow and replicate through an ordered series of events

In mitosis, chromosomes are duplicated and divided evenly
between two daughter cells.
Meiosis has two phases: Meiosis I and Meiosis II.
The difference is that sex cells are produced through meiosis, while all other body cell types are produced through mitosis.]]> 2020-06-05 19:11:05 UTC https://padlet.com/mariarojasf2022/ae10ia8ti5yi5bgw/wish/613569626 MITOSIS mariarojasf2022 https://padlet.com/mariarojasf2022/ae10ia8ti5yi5bgw/wish/613570037 It duplicates its DNA and the two daughter cells have the same pieces and genetic code.

There are five phases in the life-cycle of a cell. And PMATI is the
acronym for the phases of a cell's existence.]]> 2020-06-05 19:11:24 UTC https://padlet.com/mariarojasf2022/ae10ia8ti5yi5bgw/wish/613570037 MEIOSIS mariarojasf2022 https://padlet.com/mariarojasf2022/ae10ia8ti5yi5bgw/wish/613574362 Meiosis has two division wich create four cells. It happens when it´s time to reproduce and organism.

The cell´s genes around shuffles and does a second division soon after the first. When the second division divides the number of chromosomes in half it becomes in a haploid cell.]]> 2020-06-05 19:15:02 UTC https://padlet.com/mariarojasf2022/ae10ia8ti5yi5bgw/wish/613574362 Steps mariarojasf2022 https://padlet.com/mariarojasf2022/ae10ia8ti5yi5bgw/wish/613615362 Meiosis I
Pairs of chromosomes are lined up at the center of the cell and then pulled to each side.
In crossing-over there is a exchange of genes dividing the cell and leaving two new cells.

Meiosis II
Prophase II: DNA that remains in the cell begins to condense and form short chromosomes.
Metaphase II: All of the chromosomes line up along the center of the cell.
Anaphase II: Shows the chromosomes split and move to opposite sides of the cell.
Telophase II: Shows the DNA completely pulled to the sides and the cell membrane begins to pinch.

Finally there are four haploid cells called gametes.]]> 2020-06-05 19:49:17 UTC https://padlet.com/mariarojasf2022/ae10ia8ti5yi5bgw/wish/613615362 Genes and Protein Synthesis mariarojasf2022 https://padlet.com/mariarojasf2022/ae10ia8ti5yi5bgw/wish/613701897 Genetic code: Information in DNA and RNA that determines amino acid sequences in protein synthesis.

How does DNA transcription work?: By the transcribing of genetic information from DNA to RNA in order to produce proteins.

Translation: RNA and ribosomes work together to produce proteins.]]> 2020-06-05 21:11:43 UTC https://padlet.com/mariarojasf2022/ae10ia8ti5yi5bgw/wish/613701897 The Phases mariarojasf2022 https://padlet.com/mariarojasf2022/ae10ia8ti5yi5bgw/wish/613750078 Prophase: DNA gets duplicated, and the cell prepares for the process of mitotic division.
Metaphase: DNA lines up along a central axis and the centrioles send out tubules that connect to the DNA.
Anaphase: Half of the chromosomes are pulled to one side of the cell.
Telophase: The cell membrane closes in and  splits the cell into two pieces.
Interphase: The normal state of a cell. The cell is having all of the nutrients and energy it needs.
