Question
Chapter 45.2, Problem 2TC
Summary Introduction
To determine:
Why natural selection favors individuals whose male and female flowers bloom at different times.
Introduction:
The term “natural selection” was given and popularized by Charles Darwin. Simply, it is defined as “survival of the fittest”. It is the differential survival of organisms on the basis of their

What is the difference between self-pollination and cross-pollination? If pollen is transferred from the stamens of a flower to the stigma of the very same flower, is that cross-pollination or self-pollination? If it is transferredfrom the stamen of one flower to the stigma of another flower on the very same plant? If it is transferred from the stamen of one flower to the stigma of another flower on a different plant, but a plant that is a clone of the first one? Animals do not have pollen, of course, but why is it that most animals never have to worry about the equivalent problem of self-fertilization? Why cannot most animals fertilize themselves?
What is the dominance of seed plants on land?What is the dominance of seed plants on land?
What is the evolutionary advantage for a flowering plant to be pollinated with pollen from a different individual plant (of the same species)?

- Monoecious plants such as corn have either staminate or carpelate flowers. Knowing what you do about the molecular mechanisms of floral development, which of the following might explain the development of single-sex flowers? a. Expression of B-type genes in the presumptive carpel whorl will generate staminate flowers. b. Loss of A-type genes in the presumptive petal whorl will allow C-type and B-type genes to produce stamens instead of petals in that whorl. c. Restricting B-type gene expression to the presumptive petal whorl will generate carpelate flowers. d. All of the choices are correct.arrow_forwardWhat is pollination? Why is pollination important?
