<span>Mitosis is a part of the cell cycle in which chromosomes in a cell nucleus are separated into two identical sets of chromosomes, and each set ends up in its own nucleus.
It is important that the cells have a copy of every chromosome, so the process involves copying the chromosomes first and then carefully separating the copies to give each new cell a full set.

The daughter cells from mitosis are identical copies of the original cell.
Essential amino acids cannot be made by the body. As a result, they must come from food. The 9 essential amino acids are: histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine.
Answer:
Disease resistant traits and selective breeding.
Explanation:
Disease resistant traits in wild plants and animals are helpful if these traits are present in our plants and animals in order to maintain its high quality. We can modify both our meat and plants with the help of selective breeding of high quality plants and animals. Due to selective breeding, we can achieve the desired characteristics through modification in our plants and animals.
Answer:
Explanation:
The genetic determination of coat colors in calico cats is linked to the X chromosome wherein calicos are nearly always female, with one coat color allele linked to the maternal X chromosome and a second coat color allele linked to the paternal X chromosome.
Since, the females possess two X chromosomes (XX), they can be either homozygous for each coat colour or be heterozygote (calico). But in the males, since this trait is X- linked and males have just the one X chromosome (XY), they can only possess either of the coat colour and not be an heterozygote. But an XXY male cat can be a calico due to the presence of the two X chromosomes.
