Mary performs a PCR reaction and runs it on an agarose gel, using 100-bp ladder as her molecular weight standard. She images the gel using UV light and sees NO bands (no band in her PCR reaction and no bands for her ladder). Which of the following could explain these results? Explain each answer.
1. Mary forgot to add Gel Red when pouring the gel.
2. Mary's PCR product had an unusually high % of G and C bases.
3. Mary connected the electrodes to her gel incorrectly, swapping the positive and negative poles.

Four independent assorting genes, A, B, C and D, interact to affect the development of the retina in humans. Individuals who are homozygous recessive for either one of the genes will be able to see, individual who are homozygous recessive for either two or three genes will have diminishing sight. If an individual who has four homozygous recessive genes will be blind. In a cross between two individuals with these genotypes: AaBBccDd x AabbccDd
a. What is the probability that the child will be blind? Show calculations
b. What is the probability that the child AaBbccDD? Show calculations
