The answer is Both features have a recessive phenotype in these offspring.

An individual's phenotype is defined by their genotype and expressed genes, as well as apparent traits such as hair colour or type, eye colour, body shape, and height. It is determined by the genotype, but it is also modified by environmental circumstances.

What is genotype?

  • The genotype of a person can reveal their genetic makeup.
  • It determines which qualities will be expressed.
  • Organisms with similar appearances do not share the same genotype.
  • Biological tests can be used to determine a person's genotype.

Anettt [7]

Answer:

Man: Bb

Man’s mother: bb

Woman:Bb

Woman’s father: bb

Explanation:

Brown eyes are dominant over blue eyes, so, in order for a person to have blue eyes, they must carry both recessive alleles for blue. This means the man’s mother and the woman’s father must have the genotype bb. The man and the woman on the other hand have brown eyes, which means they got the dominant brown eye trait from their other parent and will have a heterozygous genotype Bb.
