What is the consequence of synapsis and crossing over?
A)Pure segregation of alleles along the metaphase plate
B)Tetraploidy, in which there are four copies of each chromatid
C)Diploidy of chromosome number and haploidy for DNA content
D)Random recombination of genetic material between paternal and maternal chromatids

Question

Quizplus · Accepted Answer

Synapsis allows the homologous chromosomes with four chromatids to remain in contact down the lengths of the chromatids for both the maternal and paternal chromosomes of the tetraploid pair in the early gamete. This results in a huge but usually even "shuffling" of genetic material so that at the end of the pachytene stage, the two chromosomes (with two chromatids each) are now combinations of maternal and paternal genes, rather than one pure maternally derived chromosome and one pure paternally derived chromosome. This allows for any one person to receive bits and pieces of genetic material in combination from many parental ancestors.
