Question

Challenge Question! (Combines Law of Independent Assortment and Sex-Linkage) ratio in their Fi offspring generation? Invent and design your recessive allele, and pink coat is caused by an autosomal dominant allele (wild type roma pure line is crossed with a pink male from a pure line, what will be the phenotypic Autosomal dominant disorders are associated with genes found on autosome chromosomes that have a "spoiler" effect for the phenotype. In other words, if you inherit one spoiler dominant allele for a disease, you have the disease. Question: In your own words, compare and contrast dominant and recessive disorders. Pedigrees Pedigrees are a useful tool for geneticists in that they can be used to overlay congenital (inherited) disorders over a family tree. If you understand patterns of inheritance, the frequency and patterns in which diseases are manifested in a family can tell you a lot about whether the disease is dominant, recessive, or sex-linked. Once you understand this, their most powerful application is in determining the probability of a genetic disorder showing up in the next generation. In a pedigree, a circle indicates a female, squares denote males, horizontal lines between two individuals indicate a mating pair, and vertical lines from the middle of a mating pair designate progeny. Shading of a square or circle indicates affliction with the disorder you are tracking, In this example, a man and woman have four children: two girls and two boys. One girl ls afflicted with the disorder. Roman numerals indicate the generation.

Answer 1

Female is XdXd , pp

male is Xy , PP

offsprings would be - XdX Pp , XdY pp

phenotypic ratio is 1:1

Xd is for dwarfsm

X is normal

P is for pink

p is for non pink
