Question

Which of the following did you include in your response? Check all of the boxes that apply. Women have two X chromosomes. Recessive alleles on one X chromosome are often masked by dominant alleles on the other chromosome. Women will not be affected unless they receive two recessive alleles

Answer 1

All of the statements are true.

The X chromosome is one of the two sex chromosomes of humans and some animals (the other sex chromosome is the Y chromosome). Men have a single X chromosome and women two X chromosomes.

Diseases whose gene is localized on the X chromosome are most often transmitted in the X-linked recessive mode; some are transmitted on the dominant mode related to the X.

In this mode of inheritance, the morbid allele behaves like a recessive trait.

Women heterozygotes are not affected but can transmit the disease; they are said to be conductive of the disease.

The disease is only manifested in male subjects (XY) with only one copy of the gene (hemizygous subjects)

Answer 2

All of those statements are true.
