Question
Chapter 15.3, Problem 1CC
Summary Introduction
To write:
Whether two affected individual can reproduce an unaffected offspring with a recessive mutation.
Introduction:
The genes are the hereditary unit of life and the alleles are the variant of the genes. In general, two type of alleles are present, dominant and the recessive allele. Two alleles make a functional copy of the gene.

Let’s suppose a genetic disease is caused by a mutantallele. If two affected parents produce an unaffected offspring, can themutant allele be recessive?
In flies, small wings are recessive to normal wings. If a cross between two flies produces 8 small-wing offspring and 28 normal-wing offspring, what are the most likely genotypes of the parents? (Use SS to represent the normal-wing allele and ss to represent the short-wing allele.)
Why are most genetic diseases caused by recessive alleles?
