Choose the true statements about the human and mouse genomes.
A)The human genome shares 99% of its genes with the mouse genome.
B)A comparison of genomes confirms that mice and humans shared a common ancestry more recently than humans and pufferfish.
C)Very few genes are conserved in the two genomes.
D)Little rearrangement of genes has occurred in the two genomes.

Question

Quizplus · Accepted Answer

A) The human genome does indeed share a high percentage of its genes with the mouse genome, with estimates often cited around 85% to 99%, indicating a significant genetic similarity. B) Comparative genomic studies have shown that mice and humans share a more recent common ancestor with each other than either does with more distantly related species like the pufferfish, reflecting their closer evolutionary relationship within the mammalian lineage.
