In Humans, how many chromosomes should be in each of these diploid cells after mitosis?

Answers

In humans, there will be 46 chromosomes in each of the diploid cells after mitosis. Mitosis is the equational division which results in the formation of offsprings with same number of chromosomes as that of parents.

What is Mitosis?

Mitosis is a type of cell division in which the chromosomal number remains constant from parents to the offsprings. It is therefore also known as Equational division.

Mitosis occurs in all the somatic cells of body. In this division, a parent cell divides to form two daughter cells with equal number of chromosomes. In a diploid (2n) cell, there are two sets of chromosomes whereas in a haploid (n) organism there is one set of chromosomes. In humans, the haploid set contains 23 chromosomes whereas diploid set contains 46 chromosomes (23 pairs).

Can someone give a explanation on what is Natural Selection? 15 POINTS AWARDED!​

Answers

Natural selection is the process by which species adapt to their environment. Natural selection leads to evolutionary change when individuals with certain characteristics have a greater survival or reproductive rate than other individuals in a population and pass on these inheritable genetic characteristics to their offspring. Simply put, natural selection is a consistent difference in survival and reproduction between different genotypes, or even different genes, in what we could call reproductive success. [A genotype is a group of organisms sharing a specific genetic makeup.]
