(a) Which Mimulus species would you categorize as mainly asexual reproducers? Why? (b) Which species would you categorize as mainly sexual reproducers? Why?

Short Answer

Expert verified

(a)M. rupestris and M. eastwoodiae devote more energy to producing rooted branches than making the nectar and seeds. This is why they are categorized as asexual reproducers.

(b) M. nelsonii, M. verbenaceus, and M. cardinalisdevote more energy to producing nectar and seeds than rooted branches, which is why they are classified as sexual reproducers.

Step by step solution

01

Reproduction

Reproduction refers to a process in which organisms create offspring that are genetically identical to them. Genetically, they may or may not be exact. Asexual and sexual reproduction are the two methods of reproduction. Not only is reproduction required for life, but it is also required for the planet's continued existence.

02

Explanation for part(a)

Asexual reproducers are individuals who reproduce asexually, that is, without the involvement of two parents. Because the roots will give birth to a new individual asexually, root production will be more concentrated in these types of species.

03

Explanation for part(b)

Sexual reproducers, on the other hand, are those who reproduce sexually, that is, by the fusing of male and female gametes. As a result, these species emphasize nectar and seed development to attract pollinators for the process.

What are three ways that flowering plants avoid self-fertilization?

A correlation is a way to describe the relationship between two variables. In a positive correlation, as the values of one of the variables increase, the values of the second variable also increase. In a negative correlation, as the values of one of the variables increase, the values of the second variable decrease. Or there may be no correlation between the two variables. If researchers know how two variables are correlated, they can make a prediction about one variable based on what they know about the other variable. (a) Which variable(s) is/are positively correlated with the volume of nectar production in this genus? (b) Which is/are negatively correlated? (c) Which show(s) no clear relationship?

“Bt maize”

(A) is resistant to various herbicides, making it practical to weed rice fields with those herbicides.

(B) contains transgenes that increase vitamin A content.

(C) includes bacterial genes that produce a toxin that reduces damage from insect pests.

(D) is a “boron (B)-tolerant” transgenic variety of maize.

(a) Which species would probably fare better in response to a pathogen that infects all Mimulus species? (b) Which species would fare better if a pathogen caused hummingbird populations to dwindle?

Self-fertilization, or selfing, seems to have obvious disadvantages as a reproductive “strategy” in nature, and it has even been called an “evolutionary dead end.” So it is surprising that about 20% of angiosperm species primarily rely on selfing. Suggest a reason why selfing might be advantageous and yet still be an evolutionary dead end.
