svetlana [45]

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.

Harlamova29_29 [7]

The use of minutiae in forensic science is to identify the major points in a finger prints.

<h3>What is forensic science?</h3>

Forensic science is the field of science that deals with the extraction of information especially from scene of criminal cases while making use of their physical evidence, such as fingerprints and DNA.

Minutiae points are the major features of a fingerprint image and are used in the matching of fingerprints.

Therefore, the use of minutiae in forensic science is to identify the major points in a finger prints.

Mrac [35]

The small, almond-shaped organs of the female reproductive system, suspended by ligaments in the upper lateral portion of the pelvic cavity are known as ovaries.

Ovaries are oval-shaped so are also termed almond-shaped organs and are present on the sides of the uterus in females. In females, the processes of pregnancy and ovulation which is also termed menstruation are controlled by the hormones that are made by ovaries. These hormones include estrogen and progesterone. Another major function of the ovary is that it releases the female gametes known as eggs during the menstrual cycle.

The ovaries are attached to two types of ligaments which are the ovarian ligament and suspensory ligament. Ovaries are connected to the womb by the ovarian ligament while the suspensory ligaments of the ovary contain the ovarian vessels and nerves.
