Question

if brown eyes are dominant to blue eyes, what would be the genotype of the offspring if a homozygous brown - eyed individual is crossed with a homozygous blue - eyed?

Explanation:

Step1: Define alleles

Let \(B\) represent the dominant allele for brown - eyes and \(b\) represent the recessive allele for blue - eyes. A homozygous brown - eyed individual has the genotype \(BB\), and a homozygous blue - eyed individual has the genotype \(bb\).

Step2: Perform the cross

When we cross \(BB\times bb\), all of the gametes from the \(BB\) individual are \(B\), and all of the gametes from the \(bb\) individual are \(b\). Using a Punnett - square or simple genetic cross logic, the offspring will all have the genotype \(Bb\).

Answer:

\(Bb\)
