4.In dancing bears, short fur is dominant to long fur, and curlyhair is dominant to straight. The genes for these traits arelocated on separate autosomes.
You have a large population of dancing bears with the followingallele frequencies
Short fur (S) p = 0.5, Long fur (s) q = 0.5
Curly hair (C) p = 0.3, Straight hair (c) q = 0.7
You allow the population to randomly breed for severalgenerations. You have a population of 1000 dancing bears and count510 with curly hair.
Is this population in Hardy-Weinberg equilibrium for this traitbased on the starting allele frequencies?
Multiple Choice
a.No, that is not enough with curly hair.
b.No, that is too many with curly hair.
c.Yes.

6.A species of plant that grows on rock outcrops produces achemical on its stigmas that prevents pollen germination. Aftercollecting pollen over the course of a day, the chemical wears offand all the pollen grains germinate at once with the fastestgrowing male fertilizing all or most of the eggs in the ovary.
You conduct an experiment where you mix equal amounts of pollenfrom three different plants and place it on the stigmas of threeseparate flowers on six different plants. You count the number ofseeds produced by each flower and use genetic tests to determinepaternity of the seeds.
You think that the same male plant will fertilize the most seedson all of the female plants. If so, this is an example ofdisruptive selection.
Multiple Choice
a.True.
b.False.
