Question

Some lizard species only reproduce by parthenogenesis. What can you infer about this species? Select two that apply.
a. All the organism are male
b. All the organism are female
c. New organisms develop from unfertilized eggs
d. This is a form of sexula reproduction

Answer 1

Answer: b. All the organism are female

c. New organisms develop from unfertilized eggs

Explanation:

The parthenogenesis is a asexual mode of reproduction in which the new embryos or offsprings develop directly from the unfertilized egg cells. This process does not involve the fertilization process which involves the fusion of the male and female gametes to produce zygote (a precursor of new organism).

b. and c. are correct options. As the egg cells can be produced in the female body hence, all the organisms who conduct parthenogenesis must be females. New organisms develop directly from the unfertilized eggs and there is no requirement of fertilization.
