Summary Introduction

To review:

The importance of pharyngotympanic tubes and sinuses being drained into nasal cavity and nasopharynx to be explained.

Introduction:

Pharyngotympanic tubes mainly open into the nasopharynx and they further drain into the middle ear. Sinuses, on the other hand, drain into the nasal cavity. Nasopharynx and nasal cavity help in removal of mucosal entrapments from the pharyngotympanic tubes and nasopharynx.

Question 1 In a population of Jackalopes (pictured below), horn length will vary between 0.5 and 2 feet, with the mean length somewhere around 1.05 feet. You pick Jackalopes that have horn lengths around 1.75 feet to breed as this appears to be the optimal length for battling other Jackalopes for food. After a round of breeding, you measure the offsprings' mean horn length is 1.67. What is the heritability of horns length (h2)? Is Jackalope horn length a heritable trait? (4 pts)? 12pt v Paragraph BIU A ✓
Frequency of allele A1 Question 2 The graph below shows results of two simulations, both depicting the rise in frequency of beneficial allele in a population of infinite size. The selection coefficient and the starting frequency are the same, but in one simulation the beneficial allele is dominant and in the other it is recessive. Neither allele is fixed by 500 generations. 1.0 1 0.8 0.6 0.4 2 0.2 0 0 100 200 300 400 500 Generation (a) Which simulation shows results for a dominant and which shows results for a recessive allele? How can you tell? (4 pts) (b) Neither of the alleles reaches fixation by 500 generations. If given enough time, will both of these alleles reach fixation in the population? Why or why not?

Question 14 The relative fitnesses of three genotypes are WA/A= 1.0, WA/a = 0.7, and Wa/a = 0.3. If the population starts at the allele frequency p = 0.5, what is the value of p in the next generation? (3 pts) 12pt v V Paragraph B I U D V T² v V V p O words <
