Which two of the following affect the transmission pattern of sex-linked genes?Multiple select question.whether the allele codes for a functional proteinthe sex of the offspringwhether there are multiple alleles for the same genewhether the gene is on the X or Y chromosome
Solution
The two factors that affect the transmission pattern of sex-linked genes are:
-
The sex of the offspring: This is because sex-linked genes are located on the sex chromosomes (X and Y chromosomes). In humans, for example, females have two X chromosomes, while males have one X and one Y chromosome. Therefore, a male offspring will inherit his X chromosome from his mother and his Y chromosome from his father. On the other hand, a female offspring will inherit one X chromosome from each parent. This difference in inheritance patterns can affect the transmission of sex-linked genes.
-
Whether the gene is on the X or Y chromosome: This is also important because the X and Y chromosomes carry different genes. A gene located on the X chromosome will be inherited by both male and female offspring, but a gene on the Y chromosome will only be inherited by male offspring. This can also affect the transmission pattern of sex-linked genes.
