In a population of rabbits, fur color ranges from white to black, with various shades of gray in between. Over several generations, it is observed that the population increasingly consists of white and black rabbits, with fewer gray rabbits. Which pattern of natural selection is most likely responsible for this change in fur color distribution?Question 9Answera.Directional Selectionb.Balancing Selectionc.Stabilizing Selectiond.Disruptive Selection

Suppose a white-furred rabbit breeds with a black-furred rabbit and all of their offspring have a phenotype of gray fur. What does the gene for fur color in rabbits appear to be an example of?*1 pointMosaicismCodominanceIncomplete dominanceComplete dominance

13. The coat colour in rabbits is controlled by one gene with four alleles. The gene is found on an autosome. The symbols for the alleles are shown below.F — black or brown colourFch — chinchilla colouration (greyish colour)Fh — Himalayan colouration (white body and dark ears, face, feet and tail)f — albino (white colour)The number of possible different genotypes in rabbits would be1 point46810

Consider a population of a hypothetical animal, whose fur color is determined by a single gene, called Col. From the list below choose all conditions that must be met in order for this population to be in Hardy-Weinberg equilibrium for the Col gene.Multiple select question.Animals in the population mate randomly, regardless of their genotype for the Col geneThere is no natural selection.No new mutations in any gene.There is low to moderate levels of genetic drift.No new mutations in the Col gene.

Read each of the scenarios below. Then, select the option that best represents a scenario illustrating natural selection.A In a population of birds, those with larger beak sizes are better able to crack open tough seeds, providing them with a food source during periods of scarcity. Consequently, the average beak size in the population decreases.B In a population of flowers, those with a particular color variation attract more pollinators and produce more offspring. As a result, the proportion of flowers with that color variation decreases over generations.C In a population of rabbits, those with longer legs are more successful at outrunning predators and are more likely to survive and reproduce. Over time, the average leg length in the population increases.D In a population of fish, those with brighter colors are more easily spotted by predators, leading to higher mortality rates. As a result, the proportion of fish with bright colors increases over time.

In a cross between a black guinea pig and a brown guinea pig, all of the offspring are black and none of the offspring are brown. Which of the following is most likely true?ABlack fur color is dominant in guinea pigs.BBrown fur color is dominant in guinea pigs.CNeither fur color is dominant nor recessive in guinea pigs.DBlack fur color is recessive in guinea pigs.
