1. A diploid organism has a somatic chromosome number of 16. The centromeres of the 8
homologouspairs are designated as Aa, Bb, Cc, Dd, Ee, Ff, Gg and Hh, with uppercase letters
referring to the centromeres of maternal chromosomes and lowercase letters to the centromeres
of paternal chromosomes. Each centromere represents one chromosome. Where n = the haploid
chromosome number. How many different combinations of centromeres could be produced
during meiosis?
a.) 8
b.) 64
c.) 256
d.) 512
e.) 6561
Solution
At the meiosis, total number of chromosome is 16.
During the meiosis 1st spliting of homologous chromosome take place, so each cell has 8
chromosome and centromere.
