Human Heredity & Genetic Engineering by Adrienne Rich https://padlet.com/2025richa/i6glvmp6sjjkubx5 Chapter 14 and 15 en-us 2022-05-16 16:13:17 UTC 2022-05-17 16:20:24 UTC hello@padlet.com Chapter 15 Vocab: 2025richa https://padlet.com/2025richa/i6glvmp6sjjkubx5/wish/2186048845 1. Cloning- producing a member of a population that has genetically identical cells produced from a single cell.
2. Selective breeding- produces animals with certain desired traits.
3. Hybridization- crossing dissimilar individuals to bring together the best of both organisms.
4. Inbreeding- continued breeding of individuals with similar characteristics. 
5. Polypoid- have many sets of chromosomes.

2. Nondisjunction- error that occurs in meiosis when homologous chromosomes fail to separate.
3. Genome- full set of genetic information that an organism carries its DNA.
4. sex linked gene- gen located on a sex chromosome.
5. restriction enzymes- produced by bacteria to cut DNA molecules into precise pieces called restriction fragments. ]]> 2022-05-16 16:40:01 UTC https://padlet.com/2025richa/i6glvmp6sjjkubx5/wish/2186056375 2025richa https://padlet.com/2025richa/i6glvmp6sjjkubx5/wish/2186058971 2022-05-16 16:41:39 UTC https://padlet.com/2025richa/i6glvmp6sjjkubx5/wish/2186058971 The Steps of a Pedigree Chart 2025richa https://padlet.com/2025richa/i6glvmp6sjjkubx5/wish/2186073671 Determine if the pedigree chart shows an autosomal or X-linked disease.
  If most of the males in the pedigree are affected, then the   disorder is X-linked (sex-linked).
 If it is a 50/50 ratio between men and women the disorder is autosomal.

Determine whether the disorder is dominant or recessive.
If the disorder is dominant, one of the parents must have the disorder.
If the disorder is recessive, neither parent has to have the disorder because they can be heterozygous.

Why are all X-linked alleles expressed in males, even when they are recessive? 2025richa https://padlet.com/2025richa/i6glvmp6sjjkubx5/wish/2186144577 Because everyone has at least one X chromosome; Men only have one X chromosome, so they can only inherit one copy for the trait to show up. Females would need to inherit two copies of it, which is harder. ]]> 2022-05-16 17:33:11 UTC https://padlet.com/2025richa/i6glvmp6sjjkubx5/wish/2186144577 3.

A ressecive trait will only be passed on if it is from both parents. An example of this is eye color, if someone has brown eyes from one of the parents. These genes are controlled by genes and the complete set of genes within an organisms genome, which is called its genotype. ]]> 2022-05-17 16:14:52 UTC https://padlet.com/2025richa/i6glvmp6sjjkubx5/wish/2187919766 2025richa https://padlet.com/2025richa/i6glvmp6sjjkubx5/wish/2187924951 2022-05-17 16:17:52 UTC https://padlet.com/2025richa/i6glvmp6sjjkubx5/wish/2187924951 2025richa https://padlet.com/2025richa/i6glvmp6sjjkubx5/wish/2187928004 2022-05-17 16:19:46 UTC https://padlet.com/2025richa/i6glvmp6sjjkubx5/wish/2187928004
