In humans, deaf-mute is inherited as an autosomal recessive trait. The dominant gout predisposition gene

In humans, deaf-mute is inherited as an autosomal recessive trait. The dominant gout predisposition gene is found in another pair of autosomes. What are the possible genotypes and phenotypes of children from the marriage of a deaf-mute woman who does not suffer from gout and a man with normal hearing who has gout (homozygous for these characteristics)?

Let’s designate the deaf-mute gene as b, then the gene that causes normal hearing will be B.

Let’s designate the gene that determines the predisposition to gout as C, then the gene that causes the absence of such a predisposition will be c.

A deaf-mute woman who does not have a predisposition to gout will be bbcc, because homozygosity is a condition for the phenotypic realization of both traits. She produces eggs sun.

A man with normal hearing and suffering from gout, according to the condition of the problem, is homozygous – BBCC, he will produce BС spermatozoa.

Possible offspring of such a married couple:

All children born to this married couple will be BbCc, which corresponds to the presence of hearing and a predisposition to gout.
