Multiple crosses were made between true-breeding lines of black and yellow Labrador retrievers. All the F1 progeny were black. When these progenies were intercrossed, they produced an F2 generation consisting of 91 black, 39 yellow, and 30 chocolate (brown) dogs. Based on this scenario, is it possible to mate a yellow F2 dog with a chocolate F2 dog and get black, yellow, and chocolate Lab puppies in the litter?

True or False. Automated DNA sequencing uses a single gel lane to separate products of all four chain terminator reactions.

In this technique samples are run through gels and then transferred to a nylon membrane or a filter membrane.

True or False. Sanger sequencing uses fluorescent dyes rather than radioactive isotopes to detect DNA fragments.

Which of the following is the correct order of steps in PCR?

Prokaryotic transcription produces mRNA molecules that do not contain introns.

There are 300 individuals in sample group #1 taken from population X. How many total alleles for the trait in question are present in the sample group, assuming the trait is controlled by a single codominant gene?

True or False. The difference between ddNTP and dNTP is that ddNTP has a hydrogen atom instead of a hydroxyl group on the 2’ carbon.

Genetic material must perform which three essential functions?

The purpose of the primer sequence in PCR is to:
