The proportion of their sons having the disease would be <u>zero.</u>
The 46 chromosomes found in human cells could be divided into two groups: autosomes (44) as well as sex chromosomes (2). In contrast to bacterial chromosomes, human chromosomes are typically linear. Such as bacteria, they could be housed inside the nucleus.
Let's refer to the dominant gene as XG as well as the mutant allele as Xg due to the X-linked recessive characteristic. The woman most likely possesses the genotype XG/Xg, having Xg coming from her father as well as XG from just a healthy mother.
The husband would belong to the genotype Xg/Y should he have a G6PD deficiency. A Punnett square can be utilized to estimate the genotypes of offspring due to our being aware of the parental genotypes.
This would not change the estimated percentage of sons who will be affected because the father sometimes doesn't pass on his X chromosome to their sons.
