Difficult to change - nutrients! crops won’t grow on soil that has had all of the nutrients used up. example: after growing corn in the same place for 50 years, corn will not grow anymore because all of the nutrients it needs to grow will no longer be in the soil

Yuri [45]

If there are 100 individuals in a population and 20 are homozygous for b, 60 are heterozygous, and 20 are homozygous for b, the allele frequency of b is 50%.  

Allele frequency, sometimes referred to as gene frequency, is the percentage or fractional frequency of an allele (gene variant) at a certain location in a population. What is being discussed is the proportion of chromosomes in the population that carry that allele in comparison to the entire population or sample size. The slow change in allele frequencies within a population is known as microevolution.

Taking into consideration:

1. A particular allele at a particular chromosomal region.

2. A collection of N individuals with ploidy n, which denotes that each individual's somatic cells have n copies of each chromosome (e.g. two chromosomes in the cells of diploid species).

If an allele is found in a population on I chromosomes, the allele frequency is the proportion of all I occurrences of that allele to the total number of copies of the chromosome in the population (nN). Despite being related, the genotype frequency and the allele frequency are separate and one can infer the other from the other.

Regarding cladistics
leonid [27]

Answer:

Option C, cladistics reveals relative evolutionary branching by utilizing genetic analysis

Explanation:

Cladistics classification is a way of classifying organisms biologically in a way that a relationship between their shared traits could be established which leads to identification of closely related organism and species. It further helps to identify ancestry history of closely related species to identify closely related common ancestors and the evolution of various characteristics.

Basically in  Cladistics  study, species are arranged on a phylogenetic tree based on the time of their emergence from any other group.

Hence, option C is correct.
