The ant, Myrmecia pilosula, is found in Australia and is named bulldog because of its
aggressive behavior. It is particularly interesting because it carries all its genetic
information in a single pair of chromosomes. In other words, 2n = 2. (Males are haploid
and have just one chromosome.) Which of the following figures would most likely
represent a correct configuration of chromosomes in a metaphase I cell of a female?
a) 2 chromatids beside each other in the center of the cell
b) 2 sets of sister chromatids in a line in the center of the cell
c) 2 homologous chromosomes paired in the center of the cell
d) one chromosome in the center of the cell
e) 2 chromosomes lined up in the center of the cell
What is the outcome of synapsis, a significant event in meiosis?
a)side-by-side alignment of nonhomologous chromosomes
b)side-by-side alignment of homologous chromosomes
c)chiasma segregation

b) 63
c) 126
d) 64

chromosome number in a human?
