A mating between a true breeding red, long-stamen plant with a true breeding white, short-stamen plant yields an red, long F1. This F1 is self-fertilized to produce an F2 generation that has 300 red long-stamen plants and 100 white short-stamen plants. What can you conclude? 1. The genes are tightly linked 2. The genes are not tightly linked 3. There were no observable crossover events between the genes

True or False. The coefficient of coincidence is equal to the expected over the observed double crossovers.

True or False. Telomeres are located at random places on a chromosome.

Experiments subsequent to Griffith’s 1928 experiment showed that:

You sample a number of cells that have undergone meiosis looking for the production of recombinants between the genes ec and s. You find 92 cells with no crossovers between ec and s, 6 with one crossover between ec and s, 2 with two crossovers between ec and s, and 0 with three or more crossovers. What is the map distance between the genes ec and s?

RNA was first identified as the genetic material of the tobacco mosaic virus (TMV) through an experiment in which:

Which of the following statements is not true regarding DNA replication?

Nitrogenous bases bonded to other bases in the center of the DNA molecule are held together by what type of chemical bond?

The fraction of genes that two individuals share due to common ancestry is known as:

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