Exam 6: Genetic Linkage and Mapping in Eukaryotes

The process of recombination may rarely occur during mitosis.

In fungi like Neurospora crassa, the diploid structures are called spores.

In certain algae and in most ascomycete fungi, the nuclei in the cells present in the majority of their life cycle are in the ________ condition.

In ascomycete fungi, the arrangement of the spores in the ascus that directly reflects the order in which they were produced during meiosis is called an ________.

A testcross is always performed between the individual that is heterozygous for the genes to be mapped and an individual who is ________.

In humans, there are ________ autosomal linkage groups, plus an X and Y chromosome linkage group.

An ascus that contains two parental spores and two nonparental spores is called a tetratype.

The locus is the physical place of a gene on a chromosome.

Experimental evidence that crossing over occurs between the X chromosomes of female Drosophila was provided by ________.

Stern was able to demonstrate crossing over by using the X chromosomes in corn.

Which of the following defines the principle of linkage?

Which of the following is not one of the principles of linkage that Morgan obtained from his experiments?
