Genes are found in the same order for large stretches of the X chromosome in the rat and mouse genomes,indicating
A)occurrence of aneuploidy.
B)formation of pseudogenes.
C)conservation of synteny.
D)conservation of neoteny.

Question

Quizplus · Accepted Answer

Conservation of synteny means that genes are found in the same order in different genomes, which is what is observed in the rat and mouse genomes. Aneuploidy refers to an abnormal number of chromosomes and is not indicated by the study. Pseudogenes are nonfunctional copies of genes and are not relevant to the study. Neoteny refers to the retention of juvenile traits in adult animals and is also not relevant to the study.
