Help!!!! Can anyone answer this lab questions below about mitosis!!!!
Shtirlitz [24]

Answer:

Mitosis is a division of a eukaryotic cell in which the chromosomes are evenly distributed among the daughter cells.  

In multicellular organisms, both sexual and asexual reproduction is followed by cell division, which ensures the growth and development of the organism. In addition, cell division is necessary to replace dead cells and repair injuries. New cells are constantly being added and old ones are being destroyed. About a hundred thousand more cells are created every second, and of course the same number dies. The new cells start with the division of the source cell. The cells formed in this way are called daughter cells. Stem cells can gradually divide into all the different cells in the body through mitosis.

Most of the body's cells are constantly renewed by mitosis, but there are also so-called irreplaceable cells that are formed only once in a lifetime for the life of the organism and do not regenerate by mitosis.

A recessive gene located on the X chromosome is the cause of one type of colorblindness (denoted by Xc). Let the genotype for no
Alex73 [517]

The scenario will be Son: 25% colorblind daughter: 25% colorblind son: 25% of carrier daughters with normal vision: 25% normal son

<h3>What is color blindness?</h3>

The condition is frequently inherited. Certain eye diseases and medications are also possible causes. Men are more affected than women.

Color blindness is characterized by the inability to distinguish between red and green shades.

A colorblind man's genotype is XcY, and a heterozygous carrier female's genotype is XcX. A cross between XcY and XcX would result in progeny with the following ratio=

Son: 25% colorblind daughter: 25% colorblind son: 25% of carrier daughters with normal vision: 25% normal son.

Thus, the couple is likely to have a son who is half normal and half affected. Similarly, the couple is likely to have 50% normal daughters and 50% colorblind daughters.
