As viruses cannot reproduce by themselves, they depend on the host cells that they infect to reproduce

<span>A. Acquired traits can be passed to offspring
Jean-Baptiste Lamarck first presented his Theory of Inheritance of Acquired Characteristics in 1801. According to his theory, if an organism changes in order to adapt to its environment, the changes are passed on the organism's offspring. Some of his proposed ideas in the theory, however, were dismissed by other scientists by experimenting and studying of genetics.</span>
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
Answer:
<h2>
Genotype is the set of genes( allele) of an organism.
</h2><h2>
Phenotype is the physical expression of the genetic composition of an organism.
</h2>
Explanation:
Genotype: 1. It is the genetic composition of an organism, means it is the set of genes( allels) of an organism's DNA, which is responsible for a particular trait of an organism.
2. Genotypically, an organism can be homozygous(dominant or recessive) or heterozygous. Some Alleles are dominant over other, means some can be dominant or other can be recessive.
3. Genes are responsible for all the traits in an organism, and these traits are inheritable. All the offsprings inherit all traits from their parents.
Phenotype: 1. Physical expression of the genetic composition of an organism resulted as phenotype.
2. It is the physical expression of genes (alleles) which are responsible for any trait.
