Students have asked these similar questions
In which of the following types of large-scale mutations would there be a loss of genetic information
from a cell?
a. translocation
b. deletion
c. inversion
duplication
e. both a. and b.
The origin of genes that have new functions often involves the divergence of gene duplicates.Duplicates can arise via several mechanisms. a. One mechanism of gene duplication is retrotransposition, the insertion into the genome of DNA produced by reverse transcription of a messenger RNA. These gene duplicates are often dead on arrival: they are pseudogenes as soon as they are formed. Why are such duplicates so often dead on arrival? b. A second mechanism of gene duplication occurs via unequal crossing over during meiosis. Gene duplicates formed this way are functional more often than when they arise by reverse transcription. Why is that? c. If a gene duplicate is initially functional, what are its possible ultimate fates? Which is most likely,and why?
Fossils found in strata reveal

Select one:
O a. older strata carry fossils that differ
greatly from living organisms
unused body parts decrease in size
