- Sample problems related to non Mendelian inheritanceRead, analyze and answer completely the following problems: 1. Explain why it is possible for the proband in the following pedigree to have children of blood types A, B, and AB. Considering epistatic genes, what are the possible genotypes of II-2? 2. Agouti (A) is wild type and produces alternating bands of pigment on each hair. Black (a) is recessive to agouti. A mutation on gene B (recessive b) can eliminate all color. In a cross between agouti (AABB) and albino (aabb) mice, what genotypes, phenotypes, and proportions are expected in the offspring in F1 and F2 generations?D) Genetics Problem show the table and word In certain breeds of chickens, the allele "B" is responsible for black feathers whereas the contrasting allele "b" produces feathers that are white. Another r pair of alleles influences the shape of the feathers. "F" produces straight feathers whereas the contrasting gene for "f results in the frizzled condition. Give the genotypic and phenotypic ratios to be expected from the following cross: white, frizzled hen with a heterozygous black, homozygous straight rooster. Genotypic Ratio: Phenotypic Ratio:Question:- Based on your selected mode of inheritance, show the genotypes for the following individuals. [Use these symbols for alleles: if it is autosomal, then use the symbols B - dominant, b - recessive (e.g. BB, bb etc.) if it is X-Linked, then X(B) - dominant, X(b) - recessive, and Y for Y-chromosome (e.g. X(B)X(B), X(B)Y etc.) ] I-1 I-2 II-7 II-8 III-10 III-11 III-12 IV-8 IV-9

I am confused so please show. Label Phenotypes and genotypes as you go about the Pedigree (and whatever else might be required)! Thank you again for your help, these questions confuse me). Hair or fur length in cats is controlled by a single, autosomal gene; the short hair-allele is dominant to the allele for long hair. Hair color is produced by a different gene which is located on the X chromosome. One allele for this sex-linked gene produces yellow, while an alternate allele produces black fur color; individuals which are heterozygous for these alleles are calico or tortiseshell in color. a). If a long-haired, black male is mated with a calico female homozygous for short hair, what kind of kittens will be produced in the F1generation? Give both genotypes and phenotypes; express the genotypes both symbolically and in words.
