How did adults slaves prepare children for the challenges of a life of slavery
Semenov [28]

Answer:

From the 16th to the 18th centuries, an estimated 12 million Africans crossed the Atlantic to the Americas in the trans-Atlantic slave trade. Used on plantations throughout the United States, Latin America and the Caribbean, enslaved Africans were shipped largely from West Africa. With an average life span of five to seven years, demand for slaves from Africa increasingly grew in the 18th century leading traders to take their supply from deep within the interior of the continent

Explanation:

Slave parents, in turn, sought to instill in their children a sense of loyalty to the slave community as a whole. They taught children to refer to other girls and boys as sister and brother

You discover a population of mustard plants and find it to be at Hardy–Weinberg equilibrium with respect to the R locus. Suppose
natulia [17]

Answer:

The fraction of heterozygous individuals in the population is 32/100 that equals 0.32 which is the genotipic proportion for these endividuals.

Explanation:

According to Hardy-Weinberg, the allelic frequencies in a locus are represented as p and q, referring to the alleles. The genotypic frequencies after one generation are p² (Homozygous for allele p), 2pq (Heterozygous), q² (Homozygous for the allele q). Populations in H-W equilibrium will get the same allelic frequencies generation after generation. The sum of these allelic frequencies equals 1, this is p + q = 1.

In the exposed example, the r-6 allelic frequency is 0,2. This means that if r-6=0.2, then the other allele frequency (R) is=0.8, and the sum of both the allelic frequencies equals one. This is:

p + q = 1

r-6 + R = 1  

0.2 + 0.8 = 1

Then, the genotypic proportion for the homozygous individuals RR is 0.8 ² = 0.64

The genotypic proportion for the homozygous individuals r-6r-6 is 0.2² = 0.04

And the genotypic proportion for heterozygous individuals Rr-6 is 2xRxr-6 = 2 x 0.8 x 0.2 = 0.32
