Select the statements below that are TRUE.   Select 4 correct answer(s) Question 14 options:   A)  Mutations are induced to occur in response to a selective pressure.   B)  Crossover suppression occurs when no recombinant progeny are observed between two genes located within a homozygous paracentric inversion.   C)  The ends of each chromosome are replicated by an RNA-protein complex called telomerase.   D)  When a mismatched base pair occurs during DNA replication,  mismatch repair corrects the mismatch by replacing the nucleotide on the template strand.   E)  Mutations occur spontaneously and so may be pre-existing in a population when a selective pressure arises.    F)  When two genes are linked, the frequency of recombinant types exceeds the frequency of parental types.   G)    The choice of nucleotide that is replaced to correct a mismatched basepair during  meiotic recombination is not random.     H)  Pseudo-dominance results when deletion of a gene on one homolog results in a mutant phenotype because there is not enough functional gene product in the cell.   I)  Mitotic recombination can result in homozygosis of mutant tumor suppressor genes leading to cancer.   J)  Tandem duplications that cause a mutant phenotype can revert by unequal sister chromatid recombination.

A) 

Mutations are induced to occur in response to a selective pressure.

B) 

Crossover suppression occurs when no recombinant progeny are observed between two genes located within a homozygous paracentric inversion.

C) 

The ends of each chromosome are replicated by an RNA-protein complex called telomerase.

D) 

When a mismatched base pair occurs during DNA replication,  mismatch repair corrects the mismatch by replacing the nucleotide on the template strand.

E) 

Mutations occur spontaneously and so may be pre-existing in a population when a selective pressure arises. 

F) 

When two genes are linked, the frequency of recombinant types exceeds the frequency of parental types.

G) 

H) 

Pseudo-dominance results when deletion of a gene on one homolog results in a mutant phenotype because there is not enough functional gene product in the cell.

I) 

Mitotic recombination can result in homozygosis of mutant tumor suppressor genes leading to cancer.

J) 

Tandem duplications that cause a mutant phenotype can revert by unequal sister chromatid recombination.
