Answer:
The environmental factor that could lead to a decrease in genetic variation in a tuna population is an increase in pollution (second option).
Explanation:
There is a correlation between genetic variability and environmental pollution, the latter being a factor that impacts negatively on the variability of a specific population.
The concept of pollution stress not only implies a low rate of reproduction, but it is also a factor that prevents genetic exchange with other populations, which is a factor that makes the genetic variability decrease in a population.
For these reasons an increase in pollution implies a decrease in genetic variability in a tuna population.
- <em>Other options, such as </em><u><em>an increase in food availability</em></u><em>, a</em><u><em> decrease in tuna fishing
</em></u><em> or </em><u><em>a decrease in tuna predators</em></u><em>, are environmental factors that contribute to increased genetic variability.</em>
25 percent if you make a punnet square for this it would help a lot. Homo is same and if its dominant it would be big letter like FF and homo recessive would be ff you would get FF,Ff,Ff,ff in the punnet square.
1. Calcium carbonate minerals are the building blocks for the skeletons and shells of mini marine organisms. It is important to ocean creatures because they make their shells out of this material. Examples of animal products that are primarily of calcium carbonate include seashells, egg shells, pearls, and notably coral

</span>platyrrhines belongs or relates to the primate gathering or super family Platyrrhini, including the New World monkeys, having a wide, level nose and usually a long, prehensile tail.
Memory B cells are the type of B cells which are formed after the primary infection.
These are important as they help in producing the more intense and accelerated immune response during secondary infection or when the same antigen or infectious agent enters the body.
They do so by producing the polyclonal response, that is, the same epitope is attacked by multiple copies of B cells.
