Question

Select the correct answer from each drop-down menu. The barley plant has seven pairs of chromosomes. For a gamete, the number of genetic combinations that are possible through independent assortment is ________. For a zygote produced by two barley parents, the number of possible genetic combinations is ________.

Answer 1

The number of genetic combinations possible through independent assortment is 128 for a gamete from the barley plant with seven pairs of chromosomes. The number of possible genetic combinations for a zygote produced by two barley parents is 16,384.

Step-by-step explanation:

In independent assortment, the number of possible genetic combinations for a gamete is determined by the number of chromosomes. In this case, the barley plant has seven pairs of chromosomes, so there are 2^7 possible genetic combinations, which is 128.

For a zygote produced by two barley parents, the number of possible genetic combinations is determined by the number of chromosomes from each parent. Since both parents have the same number of chromosomes, there would be 128^2 possible genetic combinations, which is 16,384.
