Two species that have recently diverged from a common ancestor might be expected to have a ________ set of genes and ________ chromosomes with these genes positioned along the chromosomes in the same order.(a) distinct, similar(b) similar, distinct(c) similar, dissimilar(d) similar, similarI had been asked this question in examination.The origin of the question is Functional Classification of Genes in chapter Genome Analysis of Bioinformatics

Answer»

The CORRECT CHOICE is (d) similar, similar

Easiest explanation: Over evolutionary TIME, the sequence of each pair of GENES will slowly diverge, as the species diverge and other changes such as gene duplication and gene loss change the gene content. In addition, the order of genes ALSO changes over evolutionary time as a result of chromosomal rearrangements.
