Homework Help: Biology

Posted by Marina on Monday, October 7, 2013 at 4:30pm.

Caenorhabditis elegans hermaphrodites have six different homologous chromosome pairs: five pairs of autosomes (called I-V) and one pair of sex chromosomes (called X). Hermaphrodites can either self-fertilize or they can be fertilized by males (which only have one X chromosome per diploid cell; i.e. males are hemizygous and designated "XO", where the "O" just represents no chromosome).

How many chromatids per diploid nucleus (in a diploid somatic cell) will there be after Telophase of mitosis in C. elegans male cells?


A. Either 5 or 6, depending on how segregation of the X chromosome occurred

B. 6

C. 11

D. 12

E. 24
