One of the concerns regarding genetic selection is that some traits for pest resistance may affect the texture of lettuce, it is known as pleiotropic effects.
<h3>What is a pleiotropic effect?</h3>
In genetics, a pleiotropic effect occurs when one gene influences the phenotypic expression of several traits.
Pleitropic effects represent a problem in breeding programs because positive selection for a trait can also produce negative selection for another trait.
In conclusion, one of the concerns regarding genetic selection is the presence of pleiotropic effects.

Answer:
Mutations influence evolution by changing the DNA that produces a variation within the gene.
Explanation:
- Mutation is the alteration or change in genetics of an organism.
- An alteration of singe base unit in DNA might also cause mutation.
- It is very important fact that only herediatary mutation is responsible for the evolution, no all mutation influences the evolution.
- The change in eggs or sperm cell is sequentially transferred to the further generation, ultimately resulting in the evolution.
A they remove it from the air
Answer:
Explanation:
Based on this information it can be said that this formation between the islands and the mainlands will most likely cause an increase in gene flow between the bird populations. Since the islands and the mainland are now connected birds from both these two different habitats will begin mating and producing progeny, thus causing gene flow to increase between these species.
