Dominant' traits will actually disappear faster if they are disadvantageous.
Think about it: if everyone who has even a single copy of a particular allele is at a disadvantage (manifests the phenotype, in this case six fingers), then even single copies are selected against.
In the case of recessive traits, selection occurs only against homozygous carriers, who may be very rare if the allele itself is rare.
A concrete example would be something like Tay-Sachs disease. If the allele that causes this were dominant, every carrier would die before adulthood, and it would occur only as a very rare de novo mutation. But because it is recessive, it persists for now; heterozygous carriers have no disadvantage.
Answer:
Release of large numbers of eggs/sperm into the water during reproduction cycles.
Explanation:
Adaptation may be defined as the change in the physical, physiological and chemical changes in the organisms that helps them to survive in their environment.
The organisms living in the rocky intertidal zone shows adaptations as they are more darker in color and has simple body organisation. The algae,crabs and snails live in the intertidal zone. They have small number of offspring that protect them from the predators.
Thus, the answer is release of large numbers of eggs/sperm into the water during reproduction cycles.
You have no answers down for me to help but here is the answer Synapse
jot down the answers next time lol
Answer:
They used artificial selection
Explanation:
Breeding animals who had desirable or good traits. For example, they bred cows who produced the most milk and plants that produced the most vegetables. :))

There is no physical way to explain how to do this on this website.
Sorry Though!
