Answer and Explanation:

Internal fertilization is characterized by sperm fertilizing the egg within the female. More protection against outside environments and predators, and therefore a higher chance of surviving until birth . The young develop within the female, receiving nourishment from the mother’s blood through a placenta. Less chance of desiccation of gametes. Internal fertilization also enhances the fertilization of eggs by a specific male since the females are more selective of their mates thus increasing chances of gametes meeting . Even though fewer offspring are produced through this method, their survival rate is higher.

A population has 1000 individuals. A PCR analysis of the genotypes of a gene associated with Lactase persistence are: LL = 450 L

ss7ja [257]

Answer:

L allele: 0.575 (or 57.5%)

l allele: 0.425 (or 42.5 %)

Explanation:

Homo-zygous individuals have two copies of the same allele (i.e., either L alelle or l allele), while heterozygous individuals carry both alleles at a time (i.e., one L allele and one l allele). In consequence:

- Frequency of the L allele: [(450 x 2) + 250] / 2000 = 0.575

- Frequency of the l allele: [(300 x 2) + 250] / 2000 = 0.425

podryga [215]

Even when asymptomatic, the virus can still be actively multiplying and killing cells in the immune system that help fight pathogens. This is further explained below.

<h3>What is a virus?</h3>

Generally, the virus is simply defined as a virus consisting of a core of genetic information, either DNA or RNA, wrapped by a capsid, which is a protective covering formed of protein.

In conclusion, It is possible for the virus to be actively reproducing and destroying immune cells even in the absence of any outward symptoms.
