Answer: Nondisjunction at meiosis II in the male parent.
Explanation: Nondisjunction in meiosis II in male drosophila may produces chromosome with XYY male progeny after fertilization. Due to nondisjunction occur in male drosophila contains one extra Y chromosome in sperm cell, therefore after fertilization, progeny does not have a single X chromosome rather they contain XYY chromosome.

In Drosophila, nondisjunction during meiosis in the parent can result in flies with abnormal numbers of sex chromosomes. Flies with a single X and no Y are male, and those with XXY are female. Which of the following events could not give rise to a male with a single X in Drosophila? Nondisjunction at meiosis II in the female parent Nondisjunction at meiosis I in the male parent Nondisjunction at meiosis I in the female parent All of these CAN...

Please answer these 3 questions please.
During an infection: One B cell can make more than two different antibodies, provided that they recognize the same antigen Each B-cell produces antibodies to a variety of antigens A variety of antibodies are produced by many B cells, but each B cell only produces one type of antibody The same type of antibody is produced by many B cells Bicoid is important for generation of the anterior-posterior axis by regulating expression of multiple...

A human zygote (a fertilized human egg) has an abnormal sex chromosome genotype of XO meaning that the zygote only has a single X chromatid and no other sex chromosomes. This abnormal genotype could have resulted from (note: to earn full credit you must correctly select ALL that are possible for resulting in an XO zygote). -a single nondisjunction event in meiosis I in the female parent -a single nondisjunction event in meiosis II in the female parent -a single...

Meiosis and Punnett Squares Remember, whenever you use Punnett Squares to solve genetics problems, be sure you are completing each of the following steps: 1) Identify the genotypes of the parents. 2) For the specific traits of interest, figure out what kinds of haploid gametes each parent can make. In each gamete, there should be one allele for each trait of interest. If there is more than one trait, make sure all...

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...
