Answer #1

4.

a)

b) Allodiploid

As the sterile individual has inherited one haploid set of chromosomes from one parent and another set from the other parent, it is an allodiploid.

b)

The chromosomal formula for the sterile hybrid is NA + NB = 14

c)

The probability that the sterile hybrid will produce viable gametes is 0. This is because the allodiploid hybrid does not have any homologus chromosomes, therefore meiosis will not proceed smoothly.

d)

f) Allotetraploid

e)

The chromosomal formula for T. turgidum is 2(NA + NB) = 4 N= 28
