What are likely outcomes for a female who is not choosy enough, and has too broad of an acceptance of reproductive signals? (Check all that apply.)
_____ Her sons may have low success attracting mates.
_____ Her fitness will be improved because she never misses a chance to mate.
_____ She may mate with males who are sick with parasites or disease.
_____ She may mate with males with less adaptive genes.
_____ Her fitness goes up due to increased efficiency by not wasting time in lengthy evaluations.
_____ She might inadvertently mate with a different species.
Clarify question:
What is the key concept addressed by the question?
The results when a female isn't maximizing fitness with mate choice.
What type of thinking is required?
This is an analyze question, you need to break down all of the given outcomes and pick the best ones. You need to select which of these outcomes would result from a female not being careful when picking a mate. The goal of mate choice is to pick the highest quality mate, thus maximizing fitness.
Gather Content:
What do you already know about mate choice and fitness? What other information is related to the question?
This question comes from the section of the textbook that discusses the role of courtship. Picking the best male gives the female the best chances of producing high quality offspring with higher fitness than other potential offspring.
Choose Answer:
Given what you now know, what information is most likely to produce the correct answer?
Anything that reduces her fitness or the fitness of her offspring is a potential downfall of not being picky when it comes to mate choice.
Reflection on Process:
Did your problem-solving process lead you to the correct answer? If not, where did the process break down or lead you astray? How can you revise your approach to produce a more desirable result?
The key to this analyze question is to understand the link between mate choice and fitness.Her lack of male selection may effect her reproductive fitness.

A karyotype is a physical representation (usually a photograph) of all of the chromosomes in a single cell; however, the cell must be in mitotic metaphase when the karyotype is made. Why?
a) Metaphase is the only stage of the cell cycle in which single chromosomes move toward the poles. b) Metaphase is the only stage of the cell cycle in which the cell membrane is permeable to dye. c) Metaphase is the only stage of the cell cycle in which both sets of homologous chromosomes are present in the cell. d) Metaphase is the only stage of the cell cycle in which the chromosomes have condensed and aligned, but have not yet separated. e) Metaphase is the only stage of the cell cycle in which both sister chromatids of each chromosome are present in the cell.
