90 million years ago (mya), a single bat species existed on a landmass. That species served as a common ancestor of the four bat species now found in the region. The image below shows how the landmasses have changed over time and the current distribution of the bat species.

Based on the geographical distribution of the bats over time, which of the following is most likely true about the evolutionary relationship of these species?

this transfer is call conjunction

the answer to the blank provided is “an autosomal gene that is required for the expression of genes on the x chromosome”.

testis-determining factor, abbreviated as td, which is more popularly known as sex-determining region y or sry protein, is a dna-binding protein or  gene-regulatory protein/transcription factor, encoded by the  sry gene. it is the gene responsible for the initiation of male gender determination in humans.
