In particular, it explains that humans have one fewer chromosome pair in their cells than apes, due to a mutation found in chromosome number 2 that caused two chromosomes to fuse into one.

Based on his findings, he proposed that two categories of chromosomal pairing patterns existed, and he denoted these categories Type A and Type B (Table 1). Table 1: Chromosome Counts in the ...

Two types of accident that will result in a mosaic of cells with different chromosome numbers may occur (Fig. 4). At anaphase, 1 chromosome may lag behind during the movement of replicated ...

Drets and Shaw wanted to determine whether the number of types of G-banding patterns was the same as the number of group D chromosomes, and whether each cell contained two chromosomes with each G ...
