A pure line of plants of genotype a/a; b/b; c/c; d/d; e/e(all recessive to wild type) was crossed to a wild type. One F1individual expressed the recessive alleles dand e.

Thisindividual arose most likely from:

A) a deletion in the quadruple homozygous recessive parent.

B) a deletion in the wild-type parent.

C) a gene mutation in the wild-type parent.

D) position effect variegation in the F1.

E) a reversion in the quadruple homozygous recessive parent.

List two new traits (structural or behavioral) that each new species of rat might demonstrate as it adapts to the conditions on two of the four islands. choose only two islands that are described in the lesson. record the island latter and the major habitat feature of the island. then list two new traits each rat subspecies might demonstrate in order to survive the habitat on that island. note: new traits should be unique to that island and be in response to that island’s habitat feature. i cannot remember islands that were names in the lesson so only answer if you have done the lesson (5.13 life science 7b) choose 2 of the islands and describe a structural and a behavioral trait for a rat on each island so 4 total answers, 2 different structurals and 2 different behaviorals, one for each rat for each island
