Answer 6

diploid but there are 3 copies of one chromosome type

Answer 8

extra genes

Question 9

Answer 9

When chromosomes have trouble pairing up for meiosis

Question 10

Answer 13

could be normal

Question 14

What happens to a gamete when the parent cell has a translocation abnormality?

Answer 14

depends on which chromatids end up in the gametes

Question 15

What is the result of the zygote when there is a deletion abnormality?

Answer 15

missing gene(s), only one instead of two
