Answer;
Heterozygote advantage occurs when heterozygotes have a higher fitness than do both homozygotes. In frequency-dependant selection, the fitness of a phenotype declines it it becomes too common in the population.
Explanation;
The heterozygotes have both alleles, which is needed for genetic variation. Heterozygotes are essential for there to be genetic variation in a population. In other words it is when When a single copy of a disease allele doesn't result in a disease but instead is good for the person or organism that carries it, we say that allele has a heterozygote advantage. For example a sickle cell trait, which protects against malaria in heterozygotes, but causes a deadly disease in homozygotes.
-Frequency-dependent selection occurs when the fitness of a genotype depends on its frequency. It is possible for the fitness of a genotype to increase (positively frequency-dependent) or decrease (negatively frequency-dependent) as the genotype frequency in the population increases.
A major problem for anthropologists when they were just studying objects in museum collections was that the objects were viewed as isolated from their cultural context.

What is Anthropology?</h3>
Anthropology is the scientific study of humans and includes the study of historical and contemporary human species as well as human behavior, biology, cultures, civilizations, and linguistics. While cultural anthropology examines cultural meaning, including norms and values, social anthropology explores patterns of behavior.
Today, the phrase sociocultural anthropology is frequently employed as a portmanteau. Language's impact on social life is the subject of linguistic anthropology. The biological evolution of people is studied in biological or physical anthropology.
Archaeological anthropology, sometimes known as "anthropology of the past," examines physical evidence to study human behavior. In North America and Asia, it is regarded as a subfield of anthropology, but in Europe it is viewed as a field unto itself or categorized under other related fields like paleontology and history.
