Question
You observe two populations of the same species of fish, but each population occurs in a different environment. Females of each population are approximately the same size, but females from one population lay an average of 100 eggs, while fish from the other population lay an average of 1,000 eggs. The eggs of females from both populations are the same size. Select ALL of the following which is likely true given the limits of life history fitness trade-offs.
The females laying 1000 eggs breed more often than the female laying 100 eggs.Explanation / Answer
The females laying 100 eggs live longer than the females laying 1000 eggs.
The females with Short life expectancy more will invest in maximum reproduction soon after attaining sexual maturity in order to ensure more offspring survival
The females laying 1000 eggs breed more often than the female laying 100 eggs.
Since egg size is same 1000 eggs are not laid in one go but in several breeding events otherwise the egg size would have been smaller.
The females laying 1000 eggs likely live in an environment that is more unpredictable than the females that lay 100 eggs.
In unpredictable environments offspring quantity is increaseed so that the probability that some offspring survives until reproduction is increased
