A human skin cell contains 46 chromosomes. A
frog sperm cell contains 12 chromosomes.
Which pair of numbers shows the chromosome
number of a normal gamete from each of these
species?
(1) human 46; frog 12 (3) human 23; frog 24
(2) human 46; frog 24 (4) human 23; frog 12

Sagot :

Answer: Human 23; frog 12

Explanation: Skin cells are somatic cells, that means the they build the body and divide by mitosis. This kind of cells have genetic charge 2n or twice of the gamete's chromosomes, so a human gamete (sperm or ovum) has 23 chromosomes (46/2 = 23).

Frog sperm cell is a gamete so it has the number of chromosomes for this type of cell which is 12

Oseniidn

The number of chromosomes for the gamete of each of the species would be half of that of their vegetative cells.

Haploid cells

Haploid cells contain half (n) the number of chromosomes of diploid cells (2n)

Gametes are generally haploid in nature.

The human skin cells are vegetative cells (2n), thus a gamete of humans would have 23 or (46/2) chromosomes.

The frog sperm cell is a gamete cell. Hence, the chromosome number remains 12.

In other words, human gametes will have 23 chromosomes while frog gametes will have 12.
