Consider the following information.

In fruit flies, dominant gene "R" produces red eyes and recessive gene "r" produces white eyes. Also, the R and r alleles are sex-linked (they are part of the X chromosome but not the Y chromosome or the autosomes). Pick the correct mating described by the following questions.
A. Rr x R- mating
B. RR x r- mating
C. rr x R- mating
D. Rr x r- mating
E. rr x r- mating

All the female offspring will have red eyes, but half the male offspring will have red eyes and half will have white eyes

DNA polymerase and other repair enzymes __________ the newly synthesized DNA strand during and after the replication process.
