Species A has a diploid number of 42 chromosomes, while species B has a diploid number of 48 chromosomes. Give the chromosome numbers found in each of the following individuals: a. An autotriploid of species A b. An autotetraploid of species B c. An allotriploid from species A and B. There are 2 possible answers to this, please indicate both correct answers

a. autotriploid of species A: 63 chromosomes

b. autotetraploid of species B: 96 chromosomes

c. allotriploid from species A and B: 1) 66 chromosomes and 2) 69 chromosomes

Explanation:

For a.

this species will have 3 haploid sets of chromosomes ('tri' means 3)

one haploid set = 21

21 × 3 = 63 chromosomes

For b.

this species will have 4 haploid sets of chromosomes ('tetra' means 4)

one haploid set = 24

24 × 4 = 96 chromosomes

For c.

there are two ways to do this:

1) two sets of chromosomes from species A and one from species B

42 + 24 = 66 chromosomes

2) one set of chromosomes from species A and two from species B

21 + 48 = 69 chromosomes

Hope that answers the question, have a great day!
