Which of the following is correct for a species that has a chromosome ...
The species is a diploid and the gametes would be haploid and contain n number of chromosomes i.e. 10. The somatic cells would contain 2n number of chromosomes i.e 20. Only 10 different types of chromosomes are present in the species.

Which of the following is correct for a species that has a chromosome ...
Chromosome number is a fundamental characteristic of a species and refers to the total number of chromosomes present in the cells of an individual. In this case, the given species has a chromosome number 2n = 20. Let's analyze each option to determine the correct answer.
a) The gametes will contain 10 chromosomes:
- Gametes are the reproductive cells, such as sperm and eggs, which are involved in sexual reproduction.
- During the process of gametogenesis (formation of gametes), the chromosome number is halved through a specialized cell division called meiosis.
- In this case, since the chromosome number is 2n = 20, the gametes will contain half of that number, which is 10 chromosomes.
- Therefore, option a) is correct.
b) The somatic cells will contain 20 chromosomes:
- Somatic cells are all the cells in the body except for the reproductive cells.
- Somatic cells undergo a different type of cell division called mitosis, which results in the production of two daughter cells with the same chromosome number as the parent cell.
- In this case, since the chromosome number is 2n = 20, the somatic cells will contain 20 chromosomes.
- Therefore, option b) is correct.
c) The gametes will contain 20 chromosomes:
- As mentioned earlier, gametes are formed through meiosis, which halves the chromosome number.
- Therefore, the gametes will not contain the same number of chromosomes as the somatic cells.
- Hence, option c) is incorrect.
d) The somatic cells contain 20 different types of chromosomes:
- This statement is not directly related to the given chromosome number.
- Chromosomes can carry different genes and variations, but the number of chromosomes itself does not determine the number of different types of chromosomes.
- Therefore, option d) is incorrect.
In summary, the correct options for a species with a chromosome number 2n = 20 are a) The gametes will contain 10 chromosomes and b) The somatic cells will contain 20 chromosomes.
a) The gametes will contain 10 chromosomes:
