Question

What are the phenotype and genotype ratios for a mix between a heterozygous dog with black (B) for and a homozygous recessive dog with brown (b) fur?

Answer 1

Phenotypic ratio; 1:1

Genotype ratio;  1:1

Explanation;

Phenotype being the observable characteristic of an individual, the resulting offsprings will be 2 black and 2 brown dogs hence a ratio of 1:1

Genotype being the genetic constitution of an individual, there will two types; two with a Bb and two also with a bb genotype. This make ratio to be also 1:1
