Answer 1

what is parthenogenesis?

${\huge{\underline{\small{\mathbb{\pink{♡Ans:-}}}}}}$Parthenogenesis is a form of reproduction in which an egg can develop into an embryo without being fertilized by a sperm. Parthenogenesis is derived from the Greek words for “virgin birth,” and several insect species including aphids, bees, and ants are known to reproduce by parthenogenesis.

Answer 2

Answer:

Parthenogenesis is defined as “obligate” when organisms exclusively reproduce through asexual means, while it is “facultative” when species that ordinarily rely on sexual reproduction can resort to facultative parthenogenesis under extenuating circumstances that isolate females from males.

The literal meaning of parthenogenesis is “virgin reproduction”—reproduction in the absence of males. Historically, parthenogenesis has been used to refer to various forms of virgin reproduction by females, including cases of haplodiploid sex determination systems under which haploid, unfertilized eggs develop into males and females develop from fertilized (diploid) eggs.
