ritance / 9 of 15 The table shows some characteristics of bottlenose dolphins that help calves survive and reach reproductive age. Characteristics of Bottlenose Dolphins • Live in social pods • Use tails for hunting • Breathe through a blowhole • Covered by smooth skin • Eat fish and squid • Deep divers over 500 meters How are MOST of these characteristics obtained? O A. through contact with their siblings O B. through eating foods that are high in proteins O C through genes that are inherited from their parents D. through interactions with other aquatic species in the ocean

ACTIVITY 3: Incomplete dominance vs. codominance Coat color in dragons is controlled by 2 alleles. A black dragon is crossed with a white dragon and all of the offspring are gray. Are the alleles incompletely dominant or codominant? ___ Explain (how do you know)? What would offspring of the other type probably look like? __
Q. 4: Given the inheritance pattern of coat color in rats described in Q 3, predict the genotype and phenotype of the parents who produced the following offspring: (a) 9/16 gray: 3/16 yellow: 3/16 black: 1/16 cream (b) 9/16 gray: 3/16 yellow: 4/16 albino (c) 27/64 gray: 16/64 albino: 9/64 yellow: 9/64 black: 3/64 cream (d) 3/8 black: 3/8 cream: 2/8 albino (e) 3/8 black: 4/8 albino: 1/8 cream

Ancestry prediction in 23 & Me is continuously updated as new individuals aregenotyped. This can change an individual’s personal predicted ancestry by refining theregion of ancestral origins or potentially identifying a less common ancestry in the lineage.This can similarly happen with animals where new breeds are identified in an individual’sancestry as new breeds are genotyped. Explain how ancestry prediction is done and howthat prediction can change as more individuals are genotyped.
1. For a particular rodent, black fur (B) is dominant over brown fur (b), and a long tail (L) is dominant over a short tail (l). Create a Punnett square that shows the genotypes of all the possible offspring that could result from the breeding of 2 rodents that are both heterozygous for both traits. Include the percentage/ratio of occurrence for each phenotype.
TRAIT: BENT FINGER 1. What are the roles of the DNA, genes and proteins in a given trait?2. How would you relate the individual trait or characteristics to proteins,genes and DNA?3. Would the manifestation of a trait be affected once the DNA nor the genesare altered?
You are examining heritability of traits implicated in disease resistance/avoidance in snails. Given the values below determine heritability. Trait VG VE VP H2 A. Level of oxidative molecules in the blood 5.33 0.65 B. Phototaxis toward dark habitat, which reduces exposure to parasites 1.36 4.72 C. Presences of proteins implicated in parasite recognition in the blood 4.26 1.63 You are examining heritability of traits implicated in disease resistance/avoidance in snails. Given the heritability values you calculated above, which trait would you select for to increase the frequency of resistant snails in the fewest number of generations and why?
6. You have identified an autosomal gene that contributesto tail size in male guppies, with a dominant allele B forlarge tails and a recessive allele b for small tails. Femaleguppies of all genotypes have similar tail sizes. Youknow that female guppies usually mate with males withthe largest tails, but the effects of population densityand the ratio of the sexes on this preference have notbeen studied. You therefore place an equal number ofmales in three tanks. In tank 1, the number of femalesis twice the number of males. In tank 2, the numbers ofmales and females are equal. In tank 3, half as manyfemales as males are present. After mating, you findthe following proportions of small-tailed males amongthe progeny: tank 1, 16%; tank 2, 25%; tank 3, 30%.a. In your original population (before the animals wereplaced in the three tanks), 25% of the males havesmall tails. Assuming that the allele frequencies inmales and females are the same, calculate the frequencies of B and b in your…
1. In humans, widow’s peak (W) is dominant over having a straight hairline (w). If a homozygous man with a widow’s peak has a child with a woman with a straight hairline, what are the odds the child will have a widow’s peak? Show work. 2. Ellis-van Creveld syndrome is a recessive inherited condition that results in 6-fingered dwarfism. Two parents without this condition have with Ellis-van Creveld syndrome. What are the genotypes of the parents and offspring? What are the odds that the son will have a 6-fingered child if his partner is a woman who is heterozygous for the condition? Show work. 3. The gene for dangling earlobes is dominant over the gene for attached earlobes. A woman with attached earlobes has a child with a man with dangling earlobes whose mother had attached earlobes. What is the probability that this child will have attached lobes? Show work. 4. In humans, normal pigmentation is due to a dominant gene, while albinism is recessive. A normally pigmented man has a…
The good genes hypothesis is a theory that explains what? why more fit individuals are more likely to have more offspring why alleles that confer beneficial traits or behaviors are selected for by natural selection why some deleterious mutations are maintained in the population why individuals of one sex develop impressive ornamental traits
