Question

One species has 2n=32 chromosomes and another species has 24 chromosomes. In an allotriploid of these two species, how many chromosomes would there be?

Answer 1

An allotriploid organism created from species with 2n=32 and 2n=24 chromosomes would have 44 chromosomes in total.

Step-by-step explanation:

In an allotriploid of two species where one species has 2n=32 chromosomes and another has 2n=24 chromosomes, the chromosome count would be a combination of three sets of chromosomes, one from the diploid species (2x) and two from the haploid (n) gametes of each species. Since allotriploids contain three sets of chromosomes, two from one species and one from the other, we calculate the number of chromosomes by adding twice the haploid number of the species with 2n=32 (which is 16) to the haploid number of the species with 2n=24 (which is 12), resulting in 16+16+12 = 44 chromosomes.
