Question

Determine whether the following scenarios are sex-linked, sex-limited or sex-influenced: " Unilateral or bilateral cryptorchidism, in which one or both testicles cannot be found in their usual position in the scrotum. Since "Mom" has no testicles, she cannot be a cryptorchid-but she can carry the gene(s) for cryptorchidism, and pass them to her sons.

Answer 1

Unilateral or bilateral cryptorchidism is a sex-limited condition that only affects males. The gene(s) for cryptorchidism are located on the non-homologous sex chromosome, which in males is the X chromosome.

Step-by-step explanation:

Unilateral or bilateral cryptorchidism is a condition in which one or both testicles cannot be found in their usual position in the scrotum. This condition is sex-limited because it affects only males. While both males and females can carry the gene(s) for cryptorchidism, only males will exhibit the condition. This is because the gene(s) for cryptorchidism are located on the non-homologous sex chromosome, which in males is the X chromosome.
