Answer:
100% Wavy hair
Explanation:
The gene involved here codes for hair texture in humans. The alleles of the gene (straight, S and curly, s) exhibits incomplete dominance. Incomplete dominance is a genetic scenario whereby one allele does not completely mask the expression of the other allele, instead an intermediate phenotype that is heterozygous is formed.
In this case, a man with curly hair (ss) marries a woman with straight hair (SS). The children from this cross will all possess a heterozygous genotype (Ss) and be phenotypically wavy-haired, since Incomplete dominance is exhibited by the gene. Therefore, 100% of the offsprings/children will have wavy hair phenotype.
The correct answer is: Disruptive selection
Disruptive selection is a type of natural selection that favors both extreme traits in a population (it is bimodal) over intermediate traits. In the example above, it favors dark and light-snails (both are extreme traits). As a consequence, the population of snails is divided into two distinct groups. This happens because snails with intermediate brightness wouldn’t have suitable environment for them, wouldn’t be adopted to either shady forest or brushy edge areas.
Answer:1) it protects the nucleic acid from digestion by enzymes, 2) contains special sites on its surface that allow the virion to attach to a host cell, and 3) provides proteins that enable the virion to penetrate the host cell membrane and, in some cases, to inject the infectious nucleic
