Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following are true about population genetics?
A
Describes the frequency of alleles and genotypes for the entire population
B
Artificial breeding is by selective crossing
C
Frequency for allele and genotype is dependent on dominance and recessiveness of alleles?
Explanation: 

Detailed explanation-1: -The relative genotype frequencies show the distribution of genetic variation in a population. Relative allele frequency is the percentage of all copies of a certain gene in a population that carry a specific allele. This is an accurate measurement of the amount of genetic variation in a population.

Detailed explanation-2: -Genotype frequency in a population is the number of individuals with a given genotype divided by the total number of individuals in the population. In population genetics, the genotype frequency is the frequency or proportion (i.e., 0 < f < 1) of genotypes in a population.

Detailed explanation-3: -Allele frequency refers to how common an allele is in a population. It is determined by counting how many times the allele appears in the population then dividing by the total number of copies of the gene.

Detailed explanation-4: -The fact that genes exist in alternate forms, called alleles, forms the basis for the study of population genetics. Populations are made up of members of the same species that interbreed.
