Answer 1

Answer:

Answer:

are reproductively isolated

Explanation:

The genetic drift represents a change in the frequency of an already existing gene variant in a population as a consequence of random sampling of organisms. The offspring would have the genes from their parents, and because the population is limited in numbers and it has been exposed to a new environment, the individuals with advantageous traits will survive and reproduce, while the others will die out gradually. This occurs when a small population of some species is reproductively isolated. The genetic variation is very small because of the small number of individuals, so only certain genes are passed on tot he offspring, thus resulting in gradual changes that will eventually lead to the creation of a separate species.

How many and what type of chromosomes would be expected in a karyotype of a human male? (1 point) 22 pairs of autosomal chromosomes and 2 Y chromosomes 23 pairs of autosomal chromosomes and 2 Y chromosomes 22 pairs of autosomal chromosomes, 1 X chromosome, and 1 Y chromosome 23 pairs of autosomal chromosomes, 1 X chromosome, and 1 Y chromosome

Answers

Remember there are 46 chromosomes in a (normal) human nucleus, which consists of 23 pairs of chromosomes.

Of these, one pair are the sex chromosomes.

In females, the sex chromosomes are XX

In males, the sex chromosomes are XY

So the karyotype of a human male would consist of 22 pairs of autosomal chromosomes, an X chromosome, and a Y chromosome.

The correct answer is

C. 22 pairs of autosomal chromosomes, 1 X chromosomes, and 1 Y chromosomes
