Meiosis is the process of one cell dividing into four reproductive cells.
As you should already know, you get half of your chromosomes from each parent for the sake of genetic variation.
Well, meiosis duplicates the chromosomes, then divides them into 4 cells, so that each new daughter cell gets <u>half</u> the amount of chromosomes as the parent cell.

Select all that apply. The principal advantages of asexual reproduction are _____.
hichkok12 [17]
The correct answers are A and C.
When an individual is reproducing asexually, it means that there is no fusing of two parent cells and meiosis, but that the offspring is produced out of the cells of one parent. This means that the organism is not '' losing time'' by trying to find a suitable mate, which enables the populations to grow at a rapid rate.
However, the offspring are genetically identical to the parent, which means that there is very little genetic variation in the population which can lead to accumulation of harmful mutations and unresponsiveness to changes in the environment.

Two alleles of a given gene exist in a population: CTGT and TGTC. (Note: The codes given are only for the transcribed strand of
Vlad [161]

Explanation:

<u>D. 6</u>

There are two forms of the gene, CTGT and TGTC, called alleles. These have undergone 3 crossover events, which may create two separate copies.

Thus 2 × 3 (# of events)= 6 new alleles

The interchange of chromosome segments, including homologous non-sister or identical chromatids. Crossing over happens at chiasmata, where non-sister chromosomes are fused together.

Further Explanation:

DNA variants on chromosomes,may have different forms called alleles. DNA, which is a genotype, is transcribed into mRNA and then converted into amino acids that are linked together by rRNA to form proteins that make up the morphology of the individual.
