Question

If a male organism has a total of 40 chromosomes in each body cell, how many total chromosomes does a female of the same species have in each body cell?

How many many homologous pairs of chromosomes does the male have?

How many chromosomes would be in a sperm or egg cell?

How many total chromosomes would the offspring have?

How many homologous pairs of chromosomes would the offspring have?

Answer 1

1. If the total number of chromosomes in male organisms is 40 then the total number of chromosome in the female species is also 40 chromosomes.

2. The homologous pairs of chromosomes the male organism has is 20 homologous.

3. The number of chromosomes which will be in the egg will be half of the chromosome. That is the egg will have 20 chromosomes.

4. The total number of chromosomes the offspring will have is 40 chromosomes.

5. The number of homologous pairs of chromosomes will the offspring will be 20 homologous.

Answer 2

1) The female will also have 40 chromosomes
2) The organism has 20 homologous pairs
3) A gamete has half the chromosome, so 20 chromosomes
4) The offspring would have the same number of chromosomes as its parents, 40
5) The offspring would have the same number of homologous pairs as its parents, 20
