The parent cell that enters meiosis is diploid, whereas the four daughter cells that result are haploid.

Which statement correctly describes how cellular DNA content and ploidy levels change during meiosis I and meiosis II?

A. DNA content is halved in both meiosis I and meiosis I. Ploidy level changes from diploid to haploid only in meiosis II.
B. DNA content is halved only in meiosis I. Ploidy level changes from diploid to haploid only in meiosis II.
C. DNA content is halved in both meiosis I and meiosis Il. Ploidy level changes from diploid to haploid in meiosis I, and remains haploid in meiosis lI.
D. DNA content is halved only in meiosis I. Ploidy level changes from diploid to haploid in meiosis I, and remains haploid in meiosis II.
E. DNA content is halved only in meiosis I. Ploidy level changes from diploid to haploid in meiosis I, and remains haploid in meiosis II.

option d

Explanation:

Meiosis stage was formerly called the reduction stage involving two divisions; meiosis I and II. After the first stage of meiosis, the ploidy level of each of the daughter cell changes is in an haploid state, meaning here the DNA content has been reduced by half. In humans (2n = 46), who have 23 pairs of chromosomes, the number of chromosomes is reduced by half at the end of meiosis I (n = 23). This haploid state is still maintained by the meiosis II just undergoing the normal mitosis division.

"1. it should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. there are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but i can't think of an example where the fears didn't turn out to be baseless.  

first, as you point out, it would be a great advance in pharmacology, to be able to tailor drugs and their doses to me. the pros involve better medical treatment. the cons involve privacy issues like insurance companies denying coverage to people with genetic risk factors. looking at dna markers wouldn't affect the frequency of genetic diseases, but it would allow detection of them earlier. and ok, actually i suppose that if people used this information to avoid having children with genetic diseases, some might decrease in frequency."

it should be briana that has it to me
