3. Environment
The simplest definition of an ecosystem is that it is a community or group of living organisms that live in and interact with each other in a specific environment.
Answer:
The correct answer is - segregation.
Explanation:
The law of segregation states that out of two factors or alleles of a gene located in an organism, only one allele or factor is distributed to each sperm cell or egg cell (gamete) randomly, So, the segregation of the alleles are random and only one allele is distributed to each gamete according to this law.
The law of segregation helps in making a different combination of alleles in a particular species or population and leads to variation in genetics. It makes sure that traits distribute to each generation randomly.
PCR allows for the analysis of DNA fragments through the comparison of the base pairs each molecule contains, which can then be used for genetic screening and the identification of individuals and DNA fragments
