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?
Discuss Concepts Many human diseases are caused by recessive alleles that are not expressed in heterozygotes. Some people think that eugenicsthe selective breeding of humans to eliminate undesirable genetic traitsprovides a way for us to rid our populations of such harmful alleles. Explain why eugenics cannot eliminate such genetic traits from human populations.
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

Activity 9GENES SEGREGATION BY BEAN-O TYPE Materials: Colored beans to represent the gene for a certain trait of garden pea. (60 pieces of the same size and shape; 30 pieces of which are of different colors from rest) Procedures: 1. Place the 30 pieces beans (one color) to one container and the other 30 pieces to the other container. Assign which color of beans will represent dominant and recessive genes of a specific trait of garden pea 2. Label the paper container as First Parent P1, male and other P1 female 3. At random, segregate the beans on the Lab table. Assume fertilization occurs and First filial generations (F1) are formed 4. Categorize the formed First filial generations 5. Put all the beans in one container. Assume that all the first filial generations undergo self-fertilization 6. Pick up the beans by two from the container without looking at it and collect the second Filial generation (F2) 7. Categorize the formed Second filial generations into two (2) phenotype, and…
