Ch. 5 Quiz 1

Another word for "linkage group" is...

• chromosome

• gene

• allele

• sister chromatid

5 genes on the same chromosome would be called...

• Neighbors

• Syntenic

• Alleles

• Proximal

The F and T genes are located on the X chromosome.

P1: FT/FT x ft/Y

F1: FT/__

F2 males:

5 FT/Y

5 Ft/Y

5 fT/Y

5 ft/Y

• The F and T genes are linked and are 50 m.u. apart

• The F and T genes are linked and are 10 m.u. apart

• The F and T genes are on different chromosomes

• The F and T genes are independently assorting

In a chi-square goodness of fit test, we are trying to support or refute...

• our hypothesis

• the null hypothesis

• the validity of our experiment

• our prediction

The reason that syntenic genes that are far apart are less reliable for mapping is...

• They are more likely to have double crossovers between them

• They are always independently assorting

• There are too many genes between them

• There is too much "junk DNA" between them

In ascospore tetrad analysis, if genes are linked we would expect...

• PD >> NPD

• NPD >> PD

• PD = NPD
