A pharmaceutical company wanted to test a new drug developed to lessen the effects of the common cold. To test this drug, scientists tested 50 volunteers, each of whom was suffering the effects of a cold. Twenty five of the people were given the drug, while the other 25 were given a placebo, a sugar pill. None of the participants knew who was taking which pill. All participants received a pill at 8:00 am daily for the first three days of the study. All participants lived in the same environment, with the same climate, eating the same diet, and having the same level of activity. The severity of the cold, hence the effectiveness of the pill, was determined by the number of tissues each person used within 24 hours. At the end of a seven day period, it was concluded that those with the sugar pill had their symptoms disappear as well as those who had taken the new wonder drug. The executive committee decided to produce the drug anyway thinking that the public would do anything to relieve the symptoms of a cold.

Independent Variable that is intentionally changed by the researcher.

How is it possible to find thenumber of heterozygotes in a
sample population, given the
allele frequencies?

Answers

To find the number of heterozygotes in a sample population, we need to know the allele frequencies and the total number of individuals in the population. The formula used to calculate the expected number of heterozygotes in a population is based on the Hardy-Weinberg equilibrium principle.

The Hardy-Weinberg equation is given as:

p² + 2pq + q² = 1

Where:

p = frequency of one (dominant) allele

q = frequency of the other allele (recessive) allele

p² = expected frequency of homozygous dominant individuals

2pq = expected frequency of heterozygous individuals

q² = expected frequency of homozygous recessive individuals

To find the number of heterozygotes, we can multiply the expected frequency of heterozygotes (2pq) by the total population size. This will give us an estimate of the number of individuals in the population who are heterozygous for the specific gene of interest.

Explanation:

The frequency of heterozygous individuals. Answer: The frequency of heterozygous individuals is equal to 2pq. In this case, 2pq equals 0.32, which means that the frequency of individuals heterozygous for this gene is equal to 32% (i.e. 2 (0.8)(0.2) = 0.32

What phenotypic ratio would you expect as a result of a test cross between two individuals where 9) one that is homozygous recessive for alleles at two independent loci?

Answers

What phenotypic ratio would you expect as a result of a test cross between a dihybrid organism and one that is homozygous recessive for alleles at two independent loci?

a. 3:1

b. 9:3:3:1

c. 1:1:1:1

d. 1:2:1

e. 9:4:2:1

Answer:

c. 1:1:1:1

Explanation:

When a heterozygous individual for two genes is test crossed with a double homozygous recessive individual, the progeny is obtained in 1:1:1:1 phenotypic ratio. This occurs as the heterozygous dominant individual forms four types of gametes in 1:1:1:1 ratio while the homozygous recessive individual would form only one type of gamete having one recessive allele for each gene.

For example, a test cross between TtRr (tall and red) and ttrr (short and white) would produce a progeny in following ratio=

1 tall, red: 1 tall, white: 1 short, red: 1 short, white

Here, T= tall, t= short, R= red, r= white

A change in genotype, but not in phenotype, is most likely due to _________.

Answers

A change in genotype, but not in phenotype, is most likely due to neutral mutation.

A mutation consists of a spontaneous and unpredictable change in the sequence of genes that make up the DNA of a living being.

A neutral mutation is one that has no consequences on the phenotype, that is, it has no effect on the observable characteristics of an organism.

Neutral mutations has effects on the genotype because it generates a change in the order of nucleotides that creates triplets that code for equivalent amino acids as basic amino acids.

Therefore, we can conclude that a neutral mutation does not affect the viability of the living being.
