A frequency of recombination that is less than 50% implies:

P1 blue-flowered, short-stalked plants (++++) and white-flowered, long-stalked plants (ffss) are crossed. The resulting F1 offspring (+f+s) are test crossed to produce the following F2 progeny: 400 blue, short 400 white, long 100 blue, long 100 white, short What is the recombination frequency, as shown in the F2 generation?

Complementary strands of a DNA double helix have opposite chemical polarity but are synthesized in the same direction (replication fork movement). This is able to happen or in other words is accounted for by:

When a gene influences many aspects of the phenotype it is said to be:

A diffuse network of thin and loosely coiled chromosomes is referred to as:

Red snapdragons are crossed with white snapdragons and in the F1 generation this cross produces pink offspring. The allele (W) controlling the red color is considered to be:

If a cytogeneticist refers to the 7p region of a chromosome, he/she is referring to the:

Half siblings, on average, share more of their genomes than to uncle-nephews.

True or False. Pericentric inversions include the centromere.

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 your epistatic pathway, is there a scenario where mating a yellow lab and a chocolate that could only result in black lab puppies?
