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...

Nondisjunction of sex chromosomes during MALE meiosis II, results in sperm with what chromosome composition? What about at Meiosis I? PLEASE DRAW A PICTURE

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
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
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...
3. Edwards syndrome is caused by an extra chromosome 18. This may result from primary nondisjunction during meiosis. The diagram represents such a meiosis beginning with a diploid cell containing synapsed chromosome 18's (a chromosome 18 bivalent) Assuming primary nondisjunction, draw in chromosome 18 in all of the cells shown, and on the lines provided write the chromosome formula (i.e., the n number) and the total number of chromosomes in every cell. For instance, on the lines by the first...
Explain the phenomenon of nondisjunction that may cure during gamete meiosis, & describe some of the consequences that can arise if nondisjunction ocures for sex and non-sex chromosomes.
The following diagram shows nondisjunction in either Meiosis I or Meiosis II. The cell has only one pair of homologous chromosomes. If fertilized with a normal healthy gamete, which cell(s) will give rise to an individual that has 2n=3? യറ്റാത Select one: a. only B b. A, B, and D C. A, C, and D d. A and D O e. only C
