Diabetes, a recessive trait, occurs in 10% of a certain population. What is the proper letter used as a symbol for the gene concerned? If a
normal female and a normal male in this population have a child who is diabetic, what is the probability that their next child will be a
diabetic?

Sagot :

Diabetes can be properly designed by using the letter symbol for the gene concerned as a lowercase letter (d) because it is a recessive trait.

What is a recessive trait?

A recessive trait is any phenotypic feature that is expressed when two recessive alleles are found in an individual and show complete dominance by means of dominant alleles that masks recessive expression.

For example, if a normal female and a normal male in the population have a child who is diabetic, then the probability that their next child will be 25% (parents are heterozygous for the trait).

In conclusion, Diabetes can be properly designed by using the letter symbol for the gene concerned as a lowercase letter (d) because it is a recessive trait.
