It’s in the picture so They travel slower than p waves, they result in much ground motion, they are produced by p and s waves
The answer you are looking for is trade winds.
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.
Examining tumor tissue for driver mutations can help plan treatments that stop cancer cells from growing.
tumors was EGFR, followed by TP53 (18%), SETD2 (11%) and SMARCA4 (11%). More than 72% (81/112) of cases have mutations in at least one driver gene.
For example, the TP53 tumor suppressor gene is a driver gene, but it is only functional when both alleles of her TP53 gene are mutated. Furthermore, mutations can act as drivers only at certain stages of cancer.
