The two-fold cost of sex refers to

A) the fact that sexual lineages multiply faster than asexual because half of the progeny are capable of producing offspring.
B) the fact that in asexual lineages, half of the offspring are males that cannot produce offspring.
C) the disadvantages of being a sexual rather than an asexual organism.
D) the fact that asexual reproduction halves the rate of replication.

Two-Fold Cost of Sex

A hypothesis in evolutionary biology that suggests sexual reproduction is twice as costly as asexual reproduction, since only females contribute to the gene pool of the offspring.

Sexual Lineages

The genetic line of descent traced through mating and reproduction, typically examined through the analysis of patterns in genetic variation.

Asexual Lineages

Populations or species that reproduce without the genetic recombination processes involved in sexual reproduction.
