anisogamy उदाहरण वाक्य

This stands in contrast to the Bateman s Principle, which claims anisogamy leads to a stronger sexual selection on males rather than females.
This concept of anisogamy affecting the evolution of mating systems and parental behaviors was adopted by a few of the initial researchers of the parental investment theory.
The first mathematical model to explain the evolution of anisogamy via individual level selection, and one that became widely accepted was the theory of gamete or sperm competition.
The three main theories for the evolution of anisogamy are gamete competition, gamete limitation, and intracellular conflicts, but the last of these three is not well supported by current evidence.
There is then a relatively sound theory base for understanding this fundamental transition from isogamy to anisogamy in the evolution of reproduction, which is predicted to be associated with the transition to multicellularity.

It has been proposed that the earliest sexual dimorphism is the size differentiation of sperm and eggs ( anisogamy ), but the evolutionary significance of sexual dimorphism is more complex than that would suggest.
Sperm competition is often compared to having selection for numerous sperm has contributed to the evolution of anisogamy with very small sperm ( because of the energy trade-off between sperm size and number ).
Mating types ( types of gametes, according to their compatibility ) may have arisen as a result of anisogamy ( gamete dimorphism ), or the male and female genders may have evolved before anisogamy.
Mating types ( types of gametes, according to their compatibility ) may have arisen as a result of anisogamy ( gamete dimorphism ), or the male and female genders may have evolved before anisogamy.
It is a form of anisogamy ( heterogamy ) in which the female gamete ( e . g . motile to the zygote, but it is usually tasked with all of the travel necessary to bring the respective gametes together.
