In humans, the glucose-6-phosphate dehydrogenase (G6PD) gene involved in sugar metabolism is X-linked. The dominant allele (G) codes for fast enzymes for normal cell functioning while the recessive allele (g) codes for slow enzymes, which are responsible for the reduced enzymatic activity of cells. However, the presence of slow enzymes has minimal effect in the overall functioning of heterozygotes, thus normal. Recessives, however, are more prone to oxidative reactions that speed up the cell damaging process, thus weak (but not lethal). If random inactivation occurs during dosage compensation, what would be the genotypes and phenotypes of the children of a heterozygous mother and a recessive father?

Question
In humans, the glucose-6-phosphate dehydrogenase (G6PD) gene involved in sugar
is X-linked. The dominant allele (G) codes for fast enzymes for normal cell functioning while the recessive
allele (g) codes for slow enzymes, which are responsible for the reduced enzymatic activity of cells.
However, the presence of slow enzymes has minimal effect in the overall functioning of heterozygotes,
thus normal. Recessives, however, are more prone to oxidative reactions that speed up the cell
damaging process, thus weak (but not lethal). If random inactivation occurs during dosage compensation,
what would be the genotypes and
father?
