Answer:
Biological predispositions
Explanation:
A Biological Predisposition is an expanded possibility of building up an infection or example of conduct dependent on the qualities we acquired from our folks (and our's folks). Qualities impact our character attributes, our IQ, our probability of getting malignant growth, and even our odds of turning into a heavy drinker.
Being predisposed to a turmoil doesn't imply that we will create it, just that we are progressively powerless against it dependent on our hereditary cosmetics. Natural hazard variables join with ecological factors, for example, stress or diet to trigger a confusion.
Research studies utilizing twins have demonstrated that numerous attributes and disarranges are heritable. For instance, in indistinguishable twin sets, on the off chance that one twin is determined to have schizophrenia, there is a half shot that the other twin will likewise be analyzed. Be that as it may, in congenial twin matches, this rate is just 15%. Since indistinguishable twins share a larger number of qualities than brotherly twins, we can infer that schizophrenia has an acquired organic premise.
Answer:
Genetic drift (sampling error)
Explanation:
According to the given information, the population under study has a small size and is more likely to be affected by genetic drift. Genetic drift refers to any chance event that leads to random changes in the allele frequencies of a population over time.
It may occur by sampling error that either makes the allele frequency 100% in the population or completely removes it from the population. Sampling error occurs quickly in the small population. The initial frequency of "blood type A" was 3/85= 0.035. Over the time period of 45 years, sampling error during gamete formation and random fertilization removed all the individuals with "blood type A" from the population and reduced its frequency to 0.
<span>The two main sources that lead to increased genetic variation are:
</span>1. Gamete mutations
2. Recombination.
Gamete mutations:
Gametic mutations are the mutations that occur in germline cells (sperm and egg). Due to this, the mutations are able to be passed on from one generation to another. One of the most famous gametic mutations<span> is hemophilia.

Recombination:
Genetic recombination is the production of offspring with combinations of traits that differ from those found in either parent.
