Having freckles is dominant (f). and not having freckles is recessive (f). a mother has ft and a father has ft. if they have a child, which genotype will make their child not have freckles?

A genotype Tt (f) will make their child not to have freckles. Only offspring with alleles containing the dominant gene 'F' will have freckles.

Explanation:

MENDEL'S PRINCIPLES OF INHERITANCE can be used to understand how genes and their alleles are passed down from one generation to the next.

The 3 principles include:

1. Law Of Dominance And Uniformity: Some alleles are dominant while others are recessive; an organism with at least one dominant allele will display the effect of the dominant allele.

2. Law of segregation: During gamete formation, the alleles for each gene segregate from each other so that each gamete carries only one allele for each gene.

3. Law of independent assortment: Genes of different traits can segregate independently during the formation of gametes.
