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>

How do organisms get their DNA?
Reil [10]
<h2>Answer </h2>

DNA are found in the cells of all living organisms

<u>Explanation</u>

DNA is a complex molecule consisting of many components which are passed from parent organisms to their offsprings during the process of reproduction. The DNA contains instruction needed for an organism to develop survive and reproduce. DNA is deoxyribonucleic acid and is contained in your body's cells. From microscopic view they are double, large cable of particles termed as nucleotides. This show the cell what proteins to produce in the living organism. Hence, all living things have DNA within their cells.

In the spotted tulip, white flowers are dominant to yellow (gene Y), and axial flowers are dominant terminal flowers (gene T). E
aleksklad [387]

Answer:

<em>9/16 A_B_ White colour, axial flower </em>

<em>3/16 A_bb White colour, terminal flower</em>

<em>3/16 aaB_ Yellow colour, axial flower</em>

<em>1/16 aabb Yellow colour, terminal flower</em>

Explanation:

Let the flower colour allele be represented by A and the flower position by B. The dominant white colour would be A while the alternate version (the yellow colour) would be a. Also, the dominant axial flower position would be B while the alternate terminal position would be b.

The Punnet's square result of crossing two plants that are heterozygous for both traits is as in the attached image.

AaBb   x   AaBb

Possible Offspring

<em>9/16 A_B_ White colour, axial flower </em>

<em>3/16 A_bb White colour, terminal flower</em>

<em>3/16 aaB_ Yellow colour, axial flower</em>

<em>1/16 aabb Yellow colour, terminal flower</em>
