The effect on
Introduction:
According to the Hardy Weinberg equilibrium, the allelic and genotypic frequencies of the population remain the same from one generation to another if there are no external evolutionary forces.

Students have asked these similar questions
1. Is there a correlation between survival, reproduction and environment color? Explain.
2. Are there any other factors besides color important in determining survival in the simulation?
3. Why did we set the rate of reproduction at 2/survivor? What would happen if one color always had more offspring than other colors?
4. Suppose that a mutation occurs and a white, “albino” bead is born. How well would it survive in your environment?
Please answer all questions please
It is said that sexual reproduction is selectively advantageous to asexual reproduciton. Why is the case?
A.
Asexual reproduction produces much more genetic diveristy than sexual reproduction
B.
Asexual repoduction is only half as efficient as sexual repdocution in sending ones genes into the next generation
C.
Sexual reproduction increases genetic diversity and consequently slows the rate of evolution
D.
Sexual reproduction is much faster than asexual repoduction
E.
Sexaul reproduction produces variation among populations which can help increase fitness for certain individuals/increase selection for favorable trait

Review the discussion of evolution and Investigating Life 1.1. Which of the following statements is/are most likely
true? (Select all that apply.)

A
Check All That Apply
Moths that could smell the nectar at the bottom of the orchid saw the need for a longer tongue,
so they grew
one that reached the nectar and passed on the longer tongue to their offspring.
Moths that could smell the nectar at the bottom of the orchid mated with females that had
longer tongues so
that their offspring might have a chance to reach the nectar
At least one moth species has always been able to reach the nectar of the orchid.
Moths with longer tongues are more likely to have access to the orchid nectar and are
therefore more likely
to survive to reproduction.

F4
Orchids with deeper nectaries are more likely to have moths rub against their pollen, and are
therefore more likely to reproduce than orchids with shallow nectaries.
