Question

Suppose that a dominant allele (M) codes for marbled patches of fur and a recessive allele (m) codes for solid fur. If a marbled-patched heterozygous individual mates with a solid fur individual, what's the probability of the phenotype and genotype combinations of the offspring?

Answer 1

50% chance of having a solid fur offspring

50% chance of having a marbled patch fur

Answer 2

Answer:

• 50% of the Offspring would have Marbled-Patched Fur (Mm)

• 50% of the Offspring would have Solid Fur (mm)

Explanation:

This is an example of Mendelian Inheritance, can be explained using a Punnett Square.

Marbled Patches (M)

Solid Fur (m)

a Marbled-Patched Heterozygous (Mm)

a Solid Fur Homozygous (mm)

m | m

M Mm | Mm

m mm | mm

• 50% of the Offspring would have Marbled-Patched Fur (Mm)

• 50% of the Offspring would have Solid Fur (mm)
