Question

A human trait is influenced by a single pair of genes with "S" representing the dominant gene and "s" representing the recessive gene. Tim (genotype SS) and Leslie (genotype ss) decide to have children. According to the principles of Mendelian heredity, what percentage of their children would exhibit the trait?

Answer 1

100% of the children would exhibit the trait.

Step-by-step explanation:

According to Mendel's laws of inheritance, each allele will segregate during gamete formation, so that each gamete could carry one allele from each gene . According to the given information and implementing the laws of Mendel, all of their offspring would have genotype "Ss" and as "S" is dominant and "s" is recessive so, all offsprings with genotype Ss would also be dominant in exhibiting the trait.
