Textbook Question
Chapter 55.7, Problem 1CS
Core Skill: Modeling The goal of this modeling challenge is to draw a set of bar graphs illustrating the relative body sizes of males and females in different mating systems: monogamy, polygyny, and polyandry. You should be able to explain your graphical model.
Modeling Challenge: Draw a bar graph with three sets of two bars each to illustrate what you think are the relative body-size ratios of males:females in monogamous, polygynous, and polyandrous species, and explain your graph. Scale the y-axis from 0 to 2.0, with 1.0 representing equal body sizes for the two sexes.

2.
Processes such as random genetic drift and founder effect can dramatically transform the genetic structure of a human group within relatively short periods of time because they can significantly reduce the effective breeding population so that the frequencies of certain genes are amplified.

A researcher when studying insects of the genus Protenor, crossed females with normal wings and short antennae, with males with short wings and long antennae. In the first generation, he found that all insects had normal wings and long antennae; Therefore, when obtaining the second generation of a count of 460 insects, 50 presented short wings and short antennae; 135 with normal wings and short antennae; 165 with short wings and long antennae; and 465 with normal wings and long antennae. According to the information, determine:a) The genotype of the F1 and the parentsb) How many pairs of genes are involved in the crossc) How is the inheritance of these characters,d) Obtain the genotypic and phenotypic relationshipe) If the test cross is made, what genotypic and phenotypic relationship is expected

- Based on Standard NGSS MS-LS3-2: Develop and use a model to describe why asexual reproduction results in offspring with identical genetic information and sexual reproduction results in offspring with genetic variation. In reference to the attached image, can you create a model that shows how it is possible that the twins ended up with such different traits yet have the same parents? Keeping in mind that the twins are a set of fraternal twins.arrow_forwardPlease check if my answer is correct. Thank you. Assuming there is random mating, find the gene frequencies, genotypic frequencies, and the proportion of individuals with the different blood types (Type A, B, AB and O) if the population is composed of the following: Type A - 80 Type AB – 35 Type B - 90 Type O - 195arrow_forwardFitness and Selection: Rodent tails A researcher is studying a rodent species with a lot of variability in tail length. Individuals may have short tails, medium tails, or long tails. The researcher has noticed that a new invasive predator, which catches prey by their tails as they try to escape, seems to catch individuals with long tails more often than those with short tails. Based on a small field trial, the relative fitness of long-tailed individuals seems to be 0.6 compared to short-tailed ones (1.0), with medium tails in-between (0.8). Use the Examples tab to predict the outcome after selection for the rodent in regions with the invasive predator. What describes the population after 100 generations of selection? Choose all that apply. A-Short Tailed individuals are the most common phenotype. B-Short Tailed individuals are the only phenotype. C-This is an example of disruptive selection. D- The long tailed phenotype is no longer present E-This is an example of directional…arrow_forward
