Question 1

During meiosis II, one spindle fiber fails to attach to a chromosome at the centromere. How will this affect the genetic content of the daughter cells?

Accepted Answer

A)  One daughter cell will have two chromosomes and the other daughter cell will have no chromosomes.
B)  One daughter cell will have only maternal genes and the other daughter cell will have only paternal genes.
C)  One daughter cell will contain one extra chromosome and the other daughter cell will have one less of that chromosome.

Question 2

Accepted Answer

Question 3

A relatively new theory has arisen regarding the development of twins at fertilization. In addition to the phenomena of identical and fraternal twins, the theory suggests that semi-identical twins called polar body twins can occur if fertilization occurs in the second polar body immediately after fertilization of the oocyte (different sperm fertilizing each) . If this is true, what should be true about the zygotes?

Accepted Answer

A)  One twin will be physically smaller than the other after birth and later in life.
B)  At least one of the twins will have a genetic abnormality due to the nature of the division that produces the secondary oocyte and polar body.
C)  The twins will possess exactly the same genetic material.
D)  The twins will have the exact same maternal genes, but their paternal genes will vary.
