Question

Below is a pedigree chart. This chart looks at individuals displaying the recessive trait.

If individual 12 got married to a male who is homozygous recessive, what would be the
probability of their offspring being homozygous recessive?

Answer 1

Answer: 25%

Explanation: The chance of the offspring to be to be a homozygous recessive trait is little since it is an recessive trait, which only expresses their phenotype if one carries two identical copies of the recessive allele. Meaning the one with the dominant allele may either be homozygous or heterozygous.
