Which of the following is an example of signal amplification?

A man who carries an allele of an X-linked gene will pass it on to _______________.

If an organism that is homozygous dominant is crossed with a heterozygote for that trait, the offspring will be __________. 

A mutation causes DNA ligase to become nonfunctional during DNA replication. Which outcome is most likely?   [Alignment Note: LO14E – Predict the effect of disrupting DNA ligase.]

The final electron acceptor during aerobic cellular respiration is______.

A woman with normal color vision, but whose father is red-green colorblind, mates with a man who is red-green colorblind. Knowing that red-green colorblindness is controlled by a gene on the X chromosome, what can you predict for their children with regard to inheritance of color vision?   [Alignment Note: LO13-C]

Recall that the gene for red or white eye color in fruit flies is X-linked, with the white color allele recessive. You examine a vial of 100 flies that are all offspring from a single genetic cross. In the vial you find that all females are red-eyed, while the males are about half red-eyed and half white-eyed. The genotypes of the parents were:   [Alignment Note: LO13-C]

Yellow fruit and dwarf vines are recessive traits in tomatoes. Red fruit and tall vines are dominant. Draw a punnett square and answer the questions for a completely dominant red and tall plant crossed with a heterozygous red and dwarf plant. What percent of the offspring will have yellow fruit and dwarf vines?
