Question

Predict the offspring of two white homozygous cats. Black is dominant to white. Use B for dominant and b for recessive. what are the genotypes and phenotypes of the new generation? what are the percentages of round and wrinkled plants?

Answer 1

Answer:

The offspring will also be white and homozygous.

Explanation:

If the two cats are white and homozygous where the gene B is for black color and dominant, gene b is for white color and recessive. In this case the genotypes of the two cats are going to be "bb" which can only lead to the same genotypes and phenotypes in their offspring. They will also be white and homozygous.

I hope this answer helps.

Answer 2

Answer:

Genotype of offspring: bb

Phenotype of offspring: white

Percentage of white offspring: 100%

Percentage of black offspring: 0%

Explanation:

Black with allele B is dominant to white with allele b.

Homozygous white will have the genotype bb.

Crossing two homozygous white cats:

bb   x   bb = bb,  bb, bb, and bb

All the offspring will be homozygous white with bb genotype.

Percentage of the offspring that are white = 100%

Percentage of the offspring that are black = 0%
