In dogs, phenotype A (erect ears and barking while following a scent) is caused by dominant alleles; phenotype B (droopy ears and silent while following a scent) is caused by recessive alleles. A dog that is homozygous for both traits of phenotype A is mated to a dog with phenotype B. If the genes for the two traits are unlinked, what is the expected F1 phenotypic ratio?

Answer:

1:0

Explanation:

A dominant trait can be described as a trait which masks the effect of a recessive trait. A recessive trait can be described as a trait which gets suppressed by a dominant trait.

In the above-mentioned scenario as the dog carrying the dominant traits has homozygous alleles for both the traits, this means that the offsprings produced will have the same phenotype as the parent with the dominant alleles.

The genes received by the recessive parent will be suppressed.
