Genetically, locus is synonymous with
a) chromosome
b) gene
c) allele
d) chromatid
e) centromere

According to the endosymbiont hypothesis, mitochondria evolve from
a) algae
b) yeast
c) cyanobacteria
d) purple non-sulfur bacteria

This one needs work...
A plant with round yellow seeds was crossed to one with wrinkled green seeds. A testcross was then done by crossing one of the F1 progeny with a wrinkled green seed parent. The results of this latter cross were: 42 round, yellow; 45 round, green; 46 wrinkled, yellow; and 45 wrinkled, green.
a) What are the genotypes for all the parents, and progeny?
b) What are the expected numbers of the four progeny types assuming independent assortment?
c) What is the X^2 value resulting from this progeny array, and is it statistically significant??



Thanks guys! I need these quick though!
