skad [1K]

Answer:

Imagine there were two pairs of chromosomes:

A paired with B

C paired with D

A gamete could have the following combinations:

A + C

A + D

B + C

B + D

Therefore, with two pairs of chromosomes, there are 4 (2²) possibilities

With seven pairs of chromosomes, there are  (2⁷) possibilities. 2⁷  = 128

For a zygote produced by two barley parents, there are two gametes fused. So we must multiply the number of combinations for each gamete. Therefore, number of possible genetic combinations is 128 x 128 = 16,384
