33. The giant panda has a diploid number of 42, which includes a pair of sex chromosomes that is analogous to human sex chromosomes (X and Y).

The kayrotype of a male panda of the giant panda species would show_____pairs of homologous autosomes and one pair of ___________sex chromosomes.

34. Why is parthenogenesis in bees considered to be a form of asexual reproduction?

a)the formation of the original haploid cell was achieved using binary fission

b)the haploid male bees were made through the process of meiosis, so they are identical to the parent egg cell.

c)although genetic material is transferred from one cell to another using conjunction, the resulting cells will be identical to each othe.

d)the male drone is made from a haploid egg. Fertilization is not part of the process to make drone.

36. Since the seedless bananas are triploid (3n), and do not produce viable seeds for reproduction. To grow more seedless banana plants, farmers take a side shoot and replant it.

a)binary fission

b)parthenogenesis

c)fragmentation

d)budding

Answer 1

ANS 38. b)3n

ANS 39. b) 28 chromosomes

i think it is a because 2*14 is 28.
