Chromosomal nondisjunction of the X chromosome in female gametes of humans can result in producing live ------
A) females with XX and males with XX
B) females with XX, and males with XY or XO
C) females with XX or XXX, and males with XY or XO
D) females with XX or XO, and males with XY or OY
E) females with XX or XXX, and males with XY or XXY
Homework Answers
Option E is the answer
XXX- This is the most common non disjunction
XXY- This is Klinefelters Syndrome
OY- This is also occurs but this is lethal as atleast 1 X chromosome is required
As the question mentioning about LIVE it does not include OY
Please give feedback!!

Genetics: Use the information gathered in the X‑Linked Inheritance animation to answer the question. In the animation, the rare white‑eyed males generated from offspring of true‑breeding red‑eyed females and white‑eyed males were the result of a nondisjunction of X chromosomes in the female during meiosis I. Could white‑eyed males be generated in this cross by a nondisjunction of X chromatids in the female during meiosis II? Why or why not? A. No, if a nondisjunction of X chromatids occurred in...

1.a) How do we know that in humans the X chromosomes play no role in sex determination, while the Y chromosome causes maleness and its absence causes femaleness? c) How do we know that X chromosomal inactivation of either the paternal or maternal homolog is a random event during early development in mammalian females? d) How do we know that Drosophila utilizes a different sex-determination mechanism than mammals, even though it has the same sex-chromosome compositions in males and females?...

Observation: Sex Chromosome Anomalies A female with Turner syndrome (XO) has only one sex chromosome, an X chromosome; the O signifies the absence of the second sex chromosome. Because the ovaries never become functional, these females do not undergo puberty or menstruation, and their breasts do not develop. Generally, females with Turner syndrome have a short build, folds of skin on the back of the neck, difficulty recognizing various spatial patterns, and normal intelligence. With hormone supplements, they can lead...

A white eyes female fruit fly is mated to a red eyed (wild type) male. While most of their progeny are as expected, occasionally a white eyed female is produced due to nondisjunction in the female. What is the likely karyotype of this white eyed daughter? (assume all fruit flies have AA as autosomes)!! (Please explain :) ) A) XX B) XXY C) XO D) XXX Y) XYY
