Figure is attached Please consider sexual selection operating on red-collared widowbirds assess the lowercase-Roman-numeral-labelled statements that appear immediately below; and click the uppercase-letter-labelled response that is presented below and conveys the most accurate information. i. The specimen depicted at the top in the figure represents the group in which individuals were manipulated experimentally, trimmed so that tail lengths were shortened substantially.ii. The specimen depicted at the bottom in the figure represents the group in which individuals were unmanipulated, left untrimmed.iii. Individuals in the group represented by the specimen at the bottom fared better in condition (measured as body mass relative to length) terms than did individuals in the group represented by the specimen at the top. iv. Individuals in the group represented by the specimen at the bottom spent more time flying and displaying to potential mates than did individuals in the group represented…

Using an evolutionary approach, explain the evolution of sexual dimorphism in height among men and women, Is this difference due to natural or sexual selection? How do know? you Male stature (cm)
Bateman (1948) and Trivers (1972) came to the conclusion that sexual selection is typically a more potent evolutionary mechanism in males than females because typically... a. Females are likely to combat each other for mates O b.Male limitations to reproductive success is gamete production O c. Males typically participate in more parental care than females O d. Females invest substantially more energy than males in gametes
Describe the advantage of using an aural or pheromone signal to attract a mate as opposed to a visual signal. How might the population density contribute to the evolution of aural or visual mating rituals?
which of thee following statement is false 1) the antagonistic pleiotropy hypothesis is used to explain why evolving to live longer is often beneficial to oneâ s fitness 2)Ribozyme is class of molecule that is made of RNAs (thus "ribo" in its name) and amino acids (thus "zyme" in its name). 3)In human population, males are in general larger than females. This observation can be seen as an example of sexual dimorphism.

Phalaropes are shore birds with brightly colored females and dull colored males. Females are larger than males and compete with each other for access to males. Considering sexual selection theory, select the idea(s) below that seem(s) most plausible in light of the pattern of sexual dimorphism? Pick all that apply This is a picture of a brightly colored female: O Females incubate eggs and care for the young. Males incubate eggs and care for the young Males are choosy. males are not choosy
80)In many species of turtles, sex is not determined by sex chromosomes (like in mammals and birds) but by the temperature the eggs are incubated at. In most species cooler temperatures produce females while warmer temperatures produce males. Sex determination in such turtles is a case of directional selection point mutation nature versus nurture phenotypic plasticity germ-line mutation
