Answer:

There is an error in the fourth option, The correct option is:

High accuracy and good validity

Explanation:

The accuracy of a measurement refers to the closeness of the measurements to the true value of what is being measured while the validity of a measurement is the degree at which the measured value correlates with the true value. In other words, validity portrays how accurate a measurement is and vice versa.

If a series of measurements are very close to the true value i.e. HIGHLY ACCURATE, then the measurements is said to have a GOOD VALIDITY i.e. it measures what it claims to measure (true value). Therefore, a HIGH ACCURACY AND GOOD VALIDITY OCCUR TOGETHER IN A MEASUREMENT because how accurate a measurement is tells you how valid it is.

Answer:

The options

a. New combinations of genes yielding genotypes of greater fitness

b. Few heterozygotes because of underdominance

c. Frequency-dependent selection, leading to fluctuations in fitness

d. Heterozygotes with greater fitness, owing to overdominance

e. A random assortment of genotypes because of genetic drift

The CORRECT ANSWER IS b.

b. Few heterozygotes because of under dominance

Explanation:

In genetics, underdominance (at times called "negative overdominance") is the opposite of overdominance.

It is the selection against the heterozygote, that leads to disruptive selection and divergent genotypes. It occurs in cases of inferior and reduced fitness (As in our case study, it is the different chromosomal fusions and inversions)

of the heterozygotic genotype to the dominant or recessive homozygotic genotype. It is unstable as it causes fixation of either allele.

Another example is the African butterfly species Pseudacraea eurytus, which makes use of Batesian mimicry to avoid predation. This species carries two alleles that gives a coloration that is alike to a different local butterfly species that is harmful to its predator. The butterflies who are heterozygous for this trait are observed to be intermediate in coloration and thus encounter an higher risk of predation and a decrease in the total fitness.

Lyrx [107]

A non random influence affecting who survives or reproduces is selective pressure. A selective pressure is considered to be a phenomenon in which behaviors of the living organisms are being driven to evolution and the natural selection in which they are also divided in to two types.
