In mice, the Sry gene is located on the Y chromosome very close to one of the pseudoautosomal regions that pairs with the X chro
makvit [3.9K]

Answer:

The model showing the condition must represent a recombination between the X and Y chromosome during meiosis in male.

Explanation:

In males, the sex chromosomes are X and Y, whereas, the females have XX chromosomes. When the X chromosome of males fuses with the female gamete it give rise to a female progeny.

The Sry gene is present on the Y chromosome. In some cases, the recombination between the X and Y chromosome during meiosis in males takes place and result in an X chromosome containing Sry gene. This Sry gene is responsible for the male characters and progeny carrying two X chromosomes, in which one has the Sry gene would have the male characters.

So, the in this case should represented the crossing over between the X and Y chromosomes in males and then passing of the Sry containing X chromosome to progeny.

butalik [34]

Answer: Tropical

Mitosis and meiosis are processes involved in cellular reproduction. Which of the following describes an event that results from
forsale [732]

The event that results from mitosis but not from meiosis is: C) daughter cells that are identical to the parent cell.

Mitosis is the process of cell division where a parent cell divides to form two daughter cells. These cells have the same number of chromosomes as that of their parent and that is the reason why the process is also known by the name equational division.

Meiosis is the process where a cell divided into 4 daughter cells and they have half of the total number of chromosomes as that of their parent. Thus is why the process is also called reductional division. Meiosis does not occur in the somatic cells of the body but in the germ cells.
