Question

Fill-in the Blanks with the corresponding terms among the following: differential, fitness, reproduction, survival, variation

Once of the most common ways to define natural selection is the phrase "Blank 1 of the fittest." This description emphasizes the importance of Blank 2 to survival and Blank 3. However, the missing element in this definition is that the Blank 4 success of individuals in a population is based on Blank 5 in their traits.

Recall:

p2 + 2pq + q2 = 1

p + q = 1

If the frequency of the r allele in a population is 0.45, what percentage of the population is likely to be homozygous recessive?

	a.	55%
	b.	45%
	c.	20%
	d.	30%

Answer 1

a)

Once of the most common ways to define natural selection is the Survival of the fittest." This description emphasizes the importance of differential to survival and fittest. However, the missing element in this definition is that the reproduction success of individuals in a population is based on variation in their traits.

b)

If the frequency of r allele is 0.45, then percent of homozygous recessive population = 0.45 x 0.45 = 0.20 or 20%. Hence, option c is correct.
