Question
Chapter 36, Problem 11TYU
Summary Introduction
To explain:
Why the offsprings of a Komodo dragon kept in isolation are not identical.
Concept introduction:
Parthenogenesis is an asexual way of reproduction in which the unfertilized egg gives rise to an organism. Meiosis, on the other hand, is a type of cell division which halves the ploidy of a cell to make gametes.

A) All stages of meiosis follow DNA replication. B) Meiosis produces gametes with the haploid chromosome number. C) Meiosis produces four identical gametes, either egg or sperm. D) Genetic variation among sexually reproducing organisms is enhanced by meiosis. Not Gradedarrow_forwardIn a possible future scenario, male fertility drops to zero, but, luckily, scientists develop a way for women to pro-duce babies by virgin birth. Meiocytes are converted di-rectly (without undergoing meiosis) into zygotes, which implant in the usual way. What would be the short- andlong-term effects in such a society?arrow_forward
