Question

What is the fundamental evolutionary trade-off between variables that constrain reproduction in mammals?

1.) quality versus quantity of offspring

2.) number of adult males versus number of adult females in a group

3.) number of estrous cycles versus female's life span

4.) sex ratio of offspring versus quantity of offspring

Answer 1

Answer: -

A trade off is a situational decision that involves decreasing one's quality, qunatity, property of a design in return for gains in other aspects. One thing must be decreased when one thing increases.

So quality versus quantity of offspring is a trade off where there is increase in no of offsprings for their better viability and for their natural selection
