Question

select the correct answer(s) from the list(s). (1 point)
sex cells receive the number of chromosomes through meiosis. errors can result in or missing chromosomes.
the same
double
half

Explanation:

1. For the first blank: During meiosis, the process of cell division that produces sex cells (gametes), the number of chromosomes in the resulting sex cells is reduced by half compared to the parent cell. This is because meiosis involves two rounds of division, resulting in cells with half the number of chromosomes (haploid) so that when fertilization occurs, the resulting zygote has the correct diploid number. So the first blank should be "half".
2. For the second blank: Errors in meiosis, such as nondisjunction, can result in gametes having an abnormal number of chromosomes. This can be either an extra chromosome (trisomy, for example) or a missing chromosome (monosomy). So the second blank should be "extra" (assuming the options for the second dropdown include "extra"—since the context is about chromosome abnormalities, the common error is having an extra or missing chromosome).

Answer:

First dropdown: half
Second dropdown: extra
