Question 2

Which of the following statements about chromosomal inversions is NOT true?

Accepted Answer

A)   The individual organisms have neither lost nor gained any genetic material.
B)   An inversion can break a gene into two parts and separate each to different locations.
C)   The expression of the gene may be altered due to the positional effect.
D)   The inversion mutations will not likely have pronounced phenotypic effects since there is no loss of genetic material.
E)   Individuals heterozygous for inversions may end up producing abnormal gametes.

Question 4

Most strains of cultivated bananas were created by crossing plants within and between two diploid species: Musa acuminata (genome = AA)  and Musa balbisiana (genome = BB) . The Cavendish banana (genome = AAA) , the variety most often sold in grocery stores, has what type of genome?

Accepted Answer

A)   allodiploid
B)   allotriploid
C)   autotriploid
D)   allotetraploid
E)   autotetraploid

Question 5

Wild-type Arabidopsis has 5 chromosomes (2n = 10) . Trisomic plants are designated as "Tr" followed by the trisomic chromosome number-that is, Tr1 is trisomic for chromosome 1. Assuming that trisomy is fully viable and that all possible pairing configurations (including nonpairing)  are possible at meiosis, what proportion of the progeny from the cross Tr1;Tr2 × Tr1;Tr2 will have a wild-type chromosomal complement?

Accepted Answer

A)   1/2
B)   1/3
C)   1/4
D)   1/9
E)   1/81

Accepted Answer

A)   deletion
B)   duplication
C)   inversion
D)   translocation
