Question

The somatic cells of mosquitoes contain six total chromosomes. Based on this information, answer the following questions.

(1pt) How many homologous pairs of chromosomes are present in a somatic cell?

(1pt) In a mosquito with no meiotic errors, how many chromosomes come from the father’s genome?

(1pt) Assuming no errors, how many chromosomes would be present in an egg cell?

(1pt)Trisomy could occur as a result of nondisjunction during meiosis. In order for nondisjunction to lead to trisomy, how many chromosomes would be present that egg cell?

(1pt) How many chromosomes would be present in a somatic cell of an adult mosquito with monosomy?

Explanation / Answer

1And. 3 homologous pairs of chromosomes can be present in somatic cell.

2 Ans. If no meiotic errors, the total 3 number of chromosomes may come from father because during meiosis chromosome number reduces to half so that father may give 3 chromosomes

3Ans. And 3 number of chromosomes may come from mother

When cells in the testes or ovary undergo meiosis, It result in formation of egg or sperm cells which are haploid, meaning that they have just one copy of each chromosome, for a total of three chromosomes.
