The evolution of similar forms in different lineages when exposed to the same selective pressures is.
luda_lava [24]

The evolution of similar forms in different lineages when exposed to the same selective pressures is<u> convergent evolution. </u>

<u></u>

Convergent or divergent evolution are related to the involved groups, the environments, the selective pressures, and the way in which organisms deal with them to achieve a better adaptation increasing their fitness.

<h3>What is convergent evolution?</h3>

Convergent evolution is the emergence of phenotypical similarities in different groups independently from each other.

Convergent evolution occurs when two or more taxonomic groups share the same traits or characteristics even when they do not share a common ancestor.

Usually, this is a pattern observed in groups that are exposed to the same or similar environmental pressures. The development of these similar phenotypes is related to higher fitness and competitive ability.

The evolution of similar forms in different lineages when exposed to the same selective pressures is <u>convergent evolution. </u>

Under what environmental conditions would a zygote not undergo meiosis
sashaice [31]

A zygote will not undergo meiosis in an environmental state that is not favorable for the zygote’s survival i.e. the chance of the zygote to survive is not certain. Take for example, chlamydomonas will form a zygote under normal asexual mitotic reproduction in a favorable environmental condition. However, under unfavorable environmental conditions the organism also reproduce sexually to form a zygote but will never proceed to meiotic division because of the unfavorable environmental state.
