Students have asked these similar questions
which of these could lead to the mistake evident in the karyotype?
A) a failure of cytokinesis after meiosis I in gamete formation
B) a nondisjunction in meiosis II in gamete formation
C) crossing over in meiosis ! in gamete formation
D) fertilizaton by two sperm in zygote formation
A man who is color blind and has hemophilia and a woman who is neither color blind nor a hemophiliac have a daughter with triple X syndrome (XXX) who has hemophilia and is color blind. Where did the nondisjunction occur?
Group of answer choices
a. Paternal meiosis II only
b. Maternal meiosis II or paternal meiosis I
c. Maternal meiosis I or paternal meiosis II
d. Paternal meiosis II or maternal meiosis II
e. Maternal meiosis II only
(b is not the right answer)
In human spermatogenesis, mitosis of a stem cell gives rise to one cell that remains a stem cell and one cell that becomes a spermatogonium. (a) Draw four rounds of mitosis for a stem cell, and label the daughter cells. (b) For one spermatogonium, draw the cells it would produce from one round of mitosis followed by meiosis. Label the cells, and label mitosis and meiosis. (c) Explain what would happen if stem cells divided like spermatogonia.
