Nondisjunction of sex chromosomes during MALE meiosis II, results in sperm with what chromosome composition? What about at Meiosis I? PLEASE DRAW A PICTURE
Non disjunction is non separation of chromosomes at meiosis 1 and of chromatids at meiosis 2 .

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...

MBG 1000 Assignment #5: Gametogenesis, Melosis & sex chromosomes (PART B) Question 3: A baby boy is bom with Klinefelter Syndrome. It is suggested that this syndrome occurred as a consequence of chromosomal nondisjunction during meiosis I of spermatogenesis. Use a diagram to indicate the sex chromosome composition of both secondary spermatocyte nuclei of the boy's father. Draw the sex chromosome composition of the nuclei of the final four sperm cells produced by spermatogenesis, the sex chromosome composition of the...
nondisjunction of the sex chromosomes during meiosis 2 in human males during gametogenesis can result in all of the following complements in a gametes EXCEPT a. no sex chromosomes b. XX c. XY d. YY e. X
if nondisjunction occurs during Meiosis II (in a male), the result would be what?
What causes de la Chapelle syndrome (XX male syndrome)? A. It is caused by two nondisjunction events. The first occurs during meiosis in the mother resulting in an XX egg, and the second occurs during meiosis in the father resulting in a sperm with no X or Y chromosomes. When this sperm fertilizes the egg it results in XX male syndrome. B. SRY is intact but the body is unable to respond to the hormone androgen, which produces the female...
Classify each description as a characteristic of nondisjunction in meiosis I or nondisjunction in meiosis II. Meiosis I Meiosis II Answer Bank results in two cells that are (n + 1) and two cells that are (n − 1) results in two abnormal cells sister chromatids fail to separate homologous chromosomes fail to separate

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...
I NEED ANSWERED ASAP!!! First, draw a cell with 6 chromosomes as it moves through the phases of meiosis. Explain what nondisjunction is. Draw and copy a picture of your drawing of your cell with 6 chromosomes to start with as it goes through the phases of meiosis with nondisjunction occurring in one chromosomes pair in meiosis I. Be sure to label the phases and indicate how many chromosomes each resulting cell will have. Label the monosomies vs. trisomies. EXTRA...
