Chapter 10, Problem 5FIB
Summary Introduction
Introduction:
Nondisjunction is the failure of separation of the chromosomal pair during anaphase stage of cell division. The nondisjunction results in an extra copy of one chromosome in one gamete and no copy of a chromosome in the other gamete. The failure in the separation of the chromosome can occur in any of the two meiotic stages because both can result in the extra chromosome or lack of chromosome in gametes.

_____ is a form of 46,XY intersex that affects chromosomal males. It is by far the most common form of 46,XY intersex. These individuals have testes that produce testosterone, but their bodies lack working androgen receptors. When these individuals are born they often have female-typical genitalia, and they develop female secondary sex characteristics at puberty. They also tend to develop a female gender identity.
A) Androgen insensitivity syndrome
B) Turner's syndrome
C)Congenital adrenal hyperplasia
D) 5-alpha reductase deficiency

- I need help filling out the chartarrow_forwardA married American lady named Vicky T., has been married for 7 years and has not been blessed with even a single child. With the consent of her husband, she decided to take fertility pills with the hope that with that medical procedure she would bear a baby. After taking the pills for 14 months, she conceived and was on the start of the 2nd trimester. In her usual check-up with her OB-Gyne, and after an ultrasound procedure, her hope to have a baby had risen to unprecedented proportions. She was told that she was carrying seven (7) babies in her womb. According to her OB-Gyne, she would not be able to have all the babies delivered as the seven would stress too much her uterus and this could be fatal to her and all her babies. Therefore, three of the designated weak babies would have to be removed before the end of the 2nd trimester. Vicky T., got confused and was in limbo. She wanted to be guided whether the procedure was ethical or not. If so, any guilt feelings she felt would be…arrow_forwardRead through the section on sex determination to answer the following scenarios. A person is born with XY chromosomes but physically and mentally presents as female until puberty. What biological factors play a role? A person with XX chromosomes are born with ambiguous genitals that resemble a penis, but they have internal ovaries. What biological factors could be involved? A person with XX chromosomes has a functional SRY gene on one of their X chromosomes. How would you expect them to develop? What role does birth order play in fetal development?arrow_forward
