Accepted Answer

A) True 
 B)False

Question 3

Genes A and B are on the same chromosome.What gametes could an AABB individual produce,if crossing over,nondisjunction or another abnormalities in meiosis occur?

Accepted Answer

A)   A, if a deletion occurs
B)   AABB, if polyploidy occurs
C)   AB, with no abnormality occurs
D)   AAB, if duplication occurs
E)   All of the answer choices are correct.F) A) and C)
G) C) and D)

Question 4

Plants have an intermediate body form called a sporophyte that undergos meiosis.The cells produced grow,through mitosis,into another intermediate body form called a gametophyte,which divides by mitosis to form gametes.The gametes fertilize,and the zygote grows,through mitosis,into another sporophyte.This form of a sexual life cycle is referred to as

Accepted Answer

A)   germination.
B)   polyploidy.
C)   crossing over.
D)   an asexual life cycle.
E)   alternation of generations.F) A) and E)
G) C) and D)

C)   all the autosomes.
D)   homologous chromosomes.
E)   found in males only.F) A) and B)
G) A) and C)

Question 6

Genes A and B are on the same chromosome.The genes have alleles A and B on one homologous chromosome,and the alleles a and b on its paired homolog.How could an individual with this allele arrangement produce a gamete with a chromosome containing the alleles Ab or aB?

Accepted Answer
