If a population of skunks includes some individuals with stripes and others with spots, would you describe the variation as quantitative or qualitative?
Imagine you are trying to test whether a population of flowers is undergoing evolution. You suspect there is selection pressure on the color of the flower: bees seem to cluster around the red flowers more often than the blue flowers. In a separate experiment, you discover blue flower color is dominant to red flower color. In a field, you count 600 blue flowers and 200 red flowers. What would you expect the genetic structure of the flowers to be?
Which description is an example of a phenotype? A certain duck has a blue beak A mutation occurred to a flower Most cheetahs live solitary lives both a and c
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
1. Describe what you think would happen if a male mouse acquired a mutation that gave it tan or a sandy colored belly AND female mice wanted to mate with this more about 1 % more than a male mouse with a white belly? 2. Now, suppose that the females were really wild about the sandy colored belly of this male mouse. The females wanted to mate with this lucky mouse about 10% more than males with a white belly? What would happen to the frequency of sandy colored bellies in this population over time? 3. What is the selective pressure at work in questions 1 & 3? 4. Describe what this statement means: "The division of humans into races by using skin color is an arbitrary social construct." 5. What are melanosomes? Name the cell type that produces melanosomes. 6.

1. A new species of animal called the rekamriliob has been found in the wild. The lab you work in has been tasked with studying its genetics. So far, there have been 2 main phenotypes found in the wild. Through selective breeding, your lab has determined that the gene for purple color (P) is dominant to the gene for golden color (p). Another lab has determined that the thick limb trait is dominant to the thin limb variety. If you breed a purebred purple thick limbed rekamreliob male with a golden thin limbed female, you get 100% thick limed offspring that are purple in color. If you take two of these organisms and breed them together, please predict the following. Assume that rekameliobs lay an average of 32 eggs. The gametes produced if the genes are unlinked b. genes The expected numbers of the possible phenotype in the offspring with unlinked The gametes produced if the genes are linked (list all possibilities, and show which ones are the result of crossing over) d. List the…
1. Given that there's a science to back you up and you actually have the capability of producing an offspring with your desired traits, would you do it? What should the limitations be if you have to put a limit on this? 2. On the other hand, give some reasons why you will not choose to do it even if there's a science to back you up and you actually have the capability of producing an offspring with your desired traits.
5) Because of extensive inbreeding, pure-bred dogs are afflicted with many genetic disorders. Most of these disorders are recessive. For example, deafness is a recessive genetic disorder affecting many breeds of dogs, especially Dalmations. Two hearing Dalmations when bred together produced 12 hearting puppies and 4 deaf puppies. What are the genotypes of all the dogs? Parents’ genotype(s)? Hearing puppies’ genotypes (multiple answers)? Deaf puppies genotype(s)? Of the hearing puppies only, how many are expected to be homozygous for this trait (use a Punnett Square to solve).
6. Consider that people with blue eyes must have two alleles for blue eyes since blue eye color is a recessive trait. A blue-eyed person and a brown-eyed person have an offspring with blue eyes. The brown-eyed person must A. have two alleles for blue eyes. B. have two alleles for brown eyes. C. not have the dominant brown eye allele. D, have one allele for blue eyes and one allele for brown eyes.
2.In dogs, there is a hereditary deafness caused by a recessive allele, d. A kennel owner has a male dog that she wants to use for breeding purposes if possible. The dog can hear, but the owner is unsure of the genotype. She does a testcross (crosses it to a homozygous recessive dog), and two of the five offspring are deaf. This means that the male dog A.has the genotype DD B.has the genotype Dd C.is still of unknown genotype since there were offspring of both deaf and hearing phenotypes. D.has the genotype dd
9) Which of the following is NOT an example of sexual selection? a.Female lesser snow geese with white feathers are more likely to mate with white-feathered males than blue-feathered males; whereas females with blue feathers are more likely to mate with blue-feathered males b.Male marine iguanas with the largest territories attract more mates than males with smaller territories c.A drab-coloured female bird prefers to mate with a male who is brightly coloured d.The largest male elephant seals, who are able to fight off smaller males, have the highest mating success
2) The more impressive the tail of a male peacock, the higher its chances of finding a mate. Female peacocks choose mates based on the color of the feathers and the overall physical prowess of the animal. However, a genetic mutation called leucism can produce a peacock with only white feathers. This mutation causes the inability of pigment to be deposited into their feathers which results in a white appearance. What would you infer to be the fitness of the white peacock? Choose ALL that apply. A) The females will equally choose the brightly colored and white peacocks as mates. Eliminate B) White peacocks are highly prized, thought to symbolize purity, eternity, and unconditional love, making them desirable mates. C) If females choose the brightest males as partners, the ones without the impressive tails will be less likely to mate and reproduce. D) White peacocks are highly prized, thought to symbolize purity, eternity, and unconditional love, causing them to…
