What advantage does monogamy give females?
By mating with more than one male over the course of her lifetime, a female gains higher genetic variation among her offspring. The benefits of monogamy, which are shared parental care and territorial resources, are maintained by having only one mate at a time, or by concealing extra-pair partnerships.
What is unusual about the reproduction of the desert grassland whiptail lizards?
Terms in this set (29) What is unusual about the reproduction of the desert grassland whiptail lizard? It is a female, asexual species. Each asexual fish is the same, so it’s just one target.
What happened to the sexually reproducing minnows in the top pool that made them more susceptible to the black spot parasite?
What happened when the drought dried up the pool? Drought dried up the pool and killed the minnows and eventually the water returned and so did the minnows; now the parasites were decimated the sexual fish and the asexual were doing well..
What are the three benefits of being in a monogamous relationship?
The benefits of monogamy include increased certainty of paternity and access to the entire reproductive potential of at least one female (Schuiling, 2003) , reduction in infanticide (Opie et al., 2013) and greater survival of offspring due to higher parental investment (Geary, 2000).
Is asexual reproduction an advantage or disadvantage for the whiptail lizard?
Those outlier liaisons gave whiptails robust heterozygosity, which has been preserved by the identical replication—essentially, cloning—that occurs in asexual reproduction. It’s a genetic-diversity advantage that today’s females still enjoy and propagate.
Do whiptail lizards have males?
Hybridization and reproduction All desert grassland whiptail lizards are female. Their reproduction process does not need male fertilization, although researchers observed pseudo-copulation that promotes fertilization during ovulation. The lizards were a result from a cross breed of two bisexual species, A.
Why did the sexually reproducing fish do better against the parasites before the drought?
Vrijenhoek found that the genetic diversity produced by sexual reproduction allowed the sexual fish to survive a parasite more successfully than the asexual fish.
Which reproduction method produces more offspring in short time?
Asexual reproduction
Asexual reproduction produces offspring that are genetically identical to the parent because the offspring are all clones of the original parent. A single individual can produce offspring asexually and large numbers of offspring can be produced quickly.
Why are monogamous relationships better?
A litany of studies have shown that people believe monogamous relationships are inherently more trusting, committed, passionate and sexually satisfying and less likely to involve jealousy than other types of relationships.
