10:14 AM Tue 9 May<●●●6. Duchenne muscular dystrophy (DMD) is an X-linked recessive condition in humans that causes muscleweakness and wasting. The allele that correctly produces the dystrophin protein (D) is dominant to the allelethat causes DMD (d). A female with the genotype XDXd reproduces with a male with the genotype XDY.What is the probability, in percent, that they will have a child with the disease?7. Which of the following correctly describes the difference between the sizes of the sex chromosomes?a. Y chromosomes are much shorter in length than X chromosomes, therefore carry more genes.b. X chromosomes are much shorter in length than Y chromosomes, therefore carry less genes.c. Y and X chromosomes are equal in length, therefore both carry the same amount of genes.d. Y chromosomes are much shorter in length than X chromosomes, therefore carry less genes.QAĈ14% 0Save 10:14 AM Tue 9 Maya) 0%b. 25%c. 50%d. 75%e.100%1. In Drosophila flies, eye color is sex-linked.

A father with the genotype XBY and a mother with the genotype XbXb have a son. What is thepercent chance that the son will inherit male-pattern baldness?RSSc. Replication of the X chromosome occurs often in males but rarely in females.d. Males mature more slowly than females, allowing recessive traits more time to appear.مدرسة روض الصالحين ثنائية اللغة4.
