Question

In meiosis, DNA replicates during

		prophase I.
		prophase II.
		interphase prior to meiosis II.
		interphase prior to meiosis I.
		both prophase I and prophase II.

2)

One of the brown eyed girls from the previous question marries a man with blue eyes. What phenotype(s) for eye color can their children have?

	A.	Brown
	B.	Blue
	C.	Green
	D.	A and B are correct
	E.	A and C are correct

3)

In lilies, red flowers (R) are dominant to white flowers (r). If two plants that are heterozygous for flower color are mated, what genotype will the offspring have?

		rr
		Rr
		RR
		RR, Rr, or rr
		None of these

4)

In humans, alleles for each gene are inherited from

		females only (moms).
		males only (dads).
		males and females (one allele from each parent).
		males and females (two alleles from each parent).
		None of the answer choices are correct.

3)

Answer 1

1) interphase prior to meiosis I.

DNA is synthesized (replicated) at S phase of interphase prior to meosis 1. Once the meosis starts there is no replication of the genetic material.

3) RR, Rr, or rr

Heterozygous parents Rr Cross Rr

Offsprins RR, Rr and rr

4)males and females (one allele from each parent).

Every individual have 2 alleles of one gene ( one in each chromosome of a homologous pair), one of which is inherited from father and the other one from the mother.
