The correct answer is 50%.
What is an allele?
- An allele is one of two, or more, forms of a given gene variant. For example, the ABO blood grouping is controlled by the ABO gene, which has six common alleles. Nearly every living human's phenotype for the ABO gene is some combination of just these six alleles.
According to the question, during the gamete formation, the genes are separated and formed the gamete.
let's assume that the A and a are the alleles that regulate the dimple in the mother. The formation of gamete with dimple and no dimple will be 50%.
Hence, the correct answer is 50%.
