In some chickens, the gene for feather colour is controlled by codominance. The allele for black is FB and the allele for white is FW. If two erminette chickens were crossed, what is the probability that they will have a black chick? Question 8 options: 0% 50% 100% 25% 75%

A scientist is studying flower color in a certain species. Red petals (R) are dominant to white petals (r). If a homozygous red-flowered plant is crossed with a heterozygous red-flowered plant, what is the probability of producing offspring with white petals?*1 point75%25%50%0%27.  A farmer is breeding rabbits for fur color. Black fur (B) is dominant to white fur (b). If two rabbits with black fur are crossed and produce offspring with both black and white fur, what can be concluded about the genotypes of the parent rabbits?*1 pointOne parent rabbit is homozygous dominant and the other is homozygous recessive.One parent rabbit is heterozygous and the other is homozygous recessive.Both parent rabbits are homozygous dominant.Both parent rabbits are heterozygous.

In some chickens, black feathers and white feathers are co-dominant traits. Chickens that have both a black feather allele and a white feather allele have black and white feathers in a sort of checkerboard pattern across their bodies.If two checkered chickens reproduce, what are the expected phenotype ratios in the offspring?Responses3 black : 1 white3 black : 1 whiteall checkered chicksall checkered chicks1 black : 3 white1 black : 3 white1 black :  2 checkered : 1 white

Feather color in chickens can be black, white, or speckled (a mix of black and white). The genotypes of these color variations are shown above. Which pattern of inheritance is present in these chickens would be , and the phenotype ratio expected from a cross between a speckled hen and a black-feathered male would be ?

In a population of birds, the frequency of the recessive allele for feather coloration (a) is 0.25. Assuming the population is in Hardy-Weinberg equilibrium, calculate the following: The frequency of individuals heterozygous for the genotype (Aa).a.0.375b.0.5625c.0.0625d.0.9375

Rooster feathering in chickens is inherited with the autosomal recessive allele r. Hen feathering is inherited with the autosomal dominant allele R. The trait is sex-limited, only males will show rooster feathering. A rooster-feathered male is mated to a hen-feathered female. All of the male offspring have rooster-feathering. What is the genotype of the hen-feathered mother?Multiple choice question.RRRrrr
