Recall Mendel's law of segregation for autosomal alleles D and d and consider the behavior of homologous chromosomes in meiosis. During which stage of M phase do these two alleles segregate from one another? (Assume no crossovers between homologs.)

A prophase I
B telophase I
C anaphase I
D metaphase I

Anaphase I

Explanation:

A cell cycle is divided into two phases - The interphase and the M-phase.During interphase the cell prepares itself for division by replicating the DNA and other cell contents. The M-phase is the actual divisional phase during which the cell divides.Cell division is of two types: Mitosis and Meiosis.Mitotic division results in two daughter cell which are identical to the parent cell while meiotic division results inf four daughter cells which have half the number of chromosomes than in parent cells. Alleles are different forms of a same gene.Alleles are located on the same loci of homologous chromosomes which separate during Anaphase I.So, we can say that the two alleles of the gene segregate during Anaphase I.

Many archeologists and anthropologists disagree with dr. thorne's view.  thorne strongly believes that what many calls "homo erectus"  was in fact  homo sapiens,  and that they migrated out of africa almost 2 million years ago and dispersed throughout europe and asia. that's way different  from what scientists have always believed about the evolution of the species.
