Species A has a diploid number of 14 chromosomes, while species B has a diploid number of 20 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 from species A and B. There are 2 possible answers to this, please indicate both correct answers. Please show all your work.

Solution

Species A (2n)= 14

Species B (2n) = 20

a. An autotriploid of species A = 21(3n= 3*7)

b. An autotetraploid of species B =40(4n=4*10)

c. An allotriploid from from species A and B = 14+10 =24(3n =2n from A and 1n from B)

7+20 =27(3n =1n from A and 2n from B)
