Explain why it is impossible for a man to be a carrier of a sex-linked trait.

Biology
1 answer:
hoa [83]4 years ago

Answer:

Because it contains two different sex chromosomes

Explanation:

Man in its genome contains two sex chromosomes, X and Y, while woman contains two X chromosomes.

In order to be a carrier of a sex-linked trait, a person should have one copy (one allele) of a certain trait. For example, if a female has one X chromosome with mutation (e.g. disease carrying) and one normal X chromosome, she is carrier for the disease. But, on the other hand if a male has one X chromosome with mutation he will develop that disease.

What is the end result of mitosis and cytokinesis? why is this so important?
makvit [3.9K]
The end result of mitosis is a cell that is exactly the same as the original cell. So, if you have Cell A and cell A goes through mitosis and produces cell B... Cell B is an exact clone/replica of cell A with NO VARIATIONS. It's literally like cloning (Asexual reproduction).

Cytokinesis is part of the cell cycle, it is the last stage where a plate forms between both the cells to separate them from each other and to form two individual cells. 

Mitosis is important because it is a fast way of producing replicas of cells. Cytokinesis is important to differentiate or create boundaries between the cells.

Sheryl is observing ovarian slides taken from a female ape. All the cells show crossover chromosomes. What is this stage?
Kobotan [32]
<span>The stage at which all the cells show crossover chromosomes is meiotic prophase I. The crossover is the exchange of genetic material between homologous chromosomes. Homologous chromosomes are present in the meiosis I. Regarding the phase of meiosis I, it is expected that the crossover takes place in meiotic prophase I since homologous chromosomes pair up in the prophase.</span>
