- Salamanders have a male heterogametic system for sex determinations where females are ZZ and males are ZW. The allele for the color of the tail is sex linked and the red allele is found on the W chromosome and the blue allele is found on the Z chromosome. You mate a male and female and they have 3 female offspring. What is the phenotypic ratio for tail color for their offspring? Group of answer choices 2 Blue : 1 Red 0 Blue : 3 Red 1 Blue : 2 red 3 Blue : 0 RedIn birds of paradise that populate tropical rainforest ecosystems, bright colored beaks and feathers are commonly found. These phenotypes continue to persist, even though brightly colored birds are more easily seen by predators. Which of the following would best describe the reason behind the persistence of these phenotypes in birds of paradise?There are two different phenotypes of a moth species, black and light grey, which are predated upon by birds. The more recently evolved black colour, is the dominant allele, B, while the recessive allele, b gives a light grey colour. Reduced pollution in the area has turned the trees (where the moths live) lighter. Which moth genotype(s) would be favoured by this change? Select one: O a. DD only O b. Dd only c. dd only O d. DD and Dd O e. DD and dd Of. Dd and dd
- Assume that you are studying the evolution of anti-predator behavior in two species of butterfly. Both species A and species B have black and orange warning coloration on their wings that is used as a warning to predators. Which of the following studies would determine whether the warning coloration in species A and species B is a homology? An evolutionary study that determines which species produces the warning coloration at a younger age. An evolutionary study that determines if the same evolutionary forces maintain the black and orange coloration in both species. An evolutionary study that determines which predators are affected by the warning coloration. An evolutionary study that reconstructs color on the larger butterfly phylogeny to determine if the common ancestor of species A and species B also had black and orange warning coloration.If the process of natural selection continues, what color of the population of the beetle would you expect to see in the environment?Since Western and Eastern meadowlarks are similar in appearance, one could assume that both are members of the same species. However, the Western meadowlark sings a song that is distinct from the Eastern meadowlark, preventing the two from mating. Therefore, one could also assume that Western and Eastern meadowlarks each represent their own species. Identify which concepts characterize both assumptions.
- Consider the following case of blending inheritance. A population of plants starts out with an equal number of individuals of heights 40 and 60 cm. The parents mate randomly, and the height of an offspring is exactly equal to the average height of its parents. Find all the ways that the heights of the grandparents average to exactly 50 cm.Since Western and Eastern meadowlarks are similar in appearance, one could assume that both are members of the same species. However, the Western meadowlark sings a song that is distinct from the Eastern meadowlark, preventing the two from mating. Therefore, one could also assume that Western and Eastern meadowlarks each represent their own species. Identify which concepts characterize both assumptions. answer for both of themConsider the following case of blending inheritance. A population of plants starts out with an equal number of individuals of heights 40 and 60 cm. The parents mate randomly, and the height of an offspring is exactly equal to the average height of its parents. What is the probability that a 60-cm tall plant mates with a 60-cm tall plant, and the probability that a 40-cm tall plant mates with a 60-cm tall plant?
- Use the the following terms to fill in the blanks: homozygous, heterozygous, dominant, recessive. (use each word once) A plant with the genotype aa has the phenotype. A plant with the genotype AA has the A plant with one dominant allele and one recessive allele is A plant with two alleles that are the same is QUESTION 2 phenotype. Use the the following terms to fill in the blanks: dominant, recessive. (use each word once) A pure breeding pea plant with yellow seeds (AA) is crossed with a pure breeding pea plant with green seeds (aa). The yellow seed trait is The green seed trait isGiven the traits of a flower below, using the Punnett square, show what fraction/percentage of offspring will most likely display red and scented? Red (R) is dominant while pink (r) is recessive. Scented (S) is dominant while unscented (s) is recessive Suppose the crossing over is between Rr/Ss and Rr/ss.Flower color variation in Phlox drummondii living either in sympatry or allopatry with Phlox cuspidata has previously been studied. Phlox drummondii exist in four colors: light blue, dark blue, light red, and dark red. Each flower color is controlled by a specific combination of alleles. In allopatry, butterflies randomly pollinate Phlox drummondii flowers of all color types. In contrast, non-random pollination occurs between differently colored flowers when both Phlox species are living in sympatry. The graph depicts the relative fitness of the alleles that drive flower color in Phlox drummondii under conditions of sympatry or allopatry with Phlox cuspidata. Label each half of the graph with the term sympatry or allopatry based on the observed trend in the relative fitness of the alleles that control all four flower colors in Phlox drummondii.
