Co dominance - genetics INGVALLEYOmega-3MANTENANCEm Fish3. In cats, the gene for calico (multicolored) cats is codominant. Females that receive a B or R gene have black andorange splotches on white coats. Males can only be black or orange, but never calico. Here's what a calico female'sgenotype would look like XB XR. Show the cross of a female black cat, with a male orange cata) What percentage of the kittens will be calico and female?b) What color will all the male cats be?4. A female cat from the litter in the previous question is bred with a black male.a) What percentage of the kittens will be black and male?b) What percentage of the kittens will be calico and male?c) What percentage of the kittens will be calico and female? 1. In some chickens, the gene for feather color is controlled by codominance. The allele for black is B and theallele for white is W. The heterozygous phenotype is known as erminette (black and white spotted) i#2erminette chickens are crossed, what is the probability that:They would have a black chick?They would have a white chick?2. Human blood types are determined by genes that follow the CODMINANCE pattern of inheritance. There are2 dominant alleles (IA and 18) and one recessive allele (i).Blood Type (Phenotype)GenotypeCan donate blood to:Can receive blood fromiiA,B,AB and OABJAJBABA.B AB.O (universalreceiver)AJA1A or 1AiАВ, АOABАB, ВO.B!al JO alala) Pretend the Brad Pitt is homozygous for the type B allele and Angelina Jolie is type "O".

In peas, the allele Le produces tall plants and the allele le produces dwarf plants. The Le allele is dominant to le. If a tall plant is crossed with a dwarf, the offspring are distributed about equally between tall and dwarf plants. What are the genotypes of the parents?
A true-breeding rabbit with agouti (mottled, grayish brown) fur crossed with a true-breeding rabbit with chinchilla (silver) fur produces all agouti offspring.

4.) A man and a woman have a child. The father is blood type A, and one of his parents was blood type A and the other was blood type O. The mother is blood type B, and one of her parents was blood type B, the other type O. Both the father and the mother are carriers of the Bombay allele. (Neither of the type-O grandparents were type O because of the Bombay allele – they had the regular type O genotype.) WhataretheoddsthattheirbabywillhavebloodtypeO?

2.In dogs, there is a hereditary deafness caused by a recessive allele, d. A kennel owner has a male dog that she wants to use for breeding purposes if possible. The dog can hear, but the owner is unsure of the genotype. She does a testcross (crosses it to a homozygous recessive dog), and two of the five offspring are deaf. This means that the male dog A.has the genotype DD B.has the genotype Dd C.is still of unknown genotype since there were offspring of both deaf and hearing phenotypes. D.has the genotype dd
