Answer:
1. B.
2. B.
3. A.
Explanation:
1. So, the mother does not but the father does carry the gene for polydactyly. Which means that, the offspring was born Pp and, the dominant trait (P) was exposed.
2. A heterozygous trait is one that has both allele forms (in this case, d and D. If both of the parents are Dd, the offspring will also be Dd, and therefore, he has 1/2 chance of being born deaf.
3. Both you and your spouse will be heterozygous (Ee), therefore, since unattached earlobes are dominant
3.1 When two heterozygous traits are bred, you will get the following combinations: yy, Yy, Yy and YY. Which means that your offspring had a 1/4 chance of having attached earlobes, and that is what happened.
3.2 The third option is incorrect, because when you breed 2 homozygous recessive (ee) traits, all of your offspring will be homozygous recessive (ee), which means that the parents would have to be homozygous recessive, but, they cannot since the dominant trait has applied to them.
Answer:
The two forms interbreed and their offspring survive and reproduce well.
Explanation:
When talking about classification of species, one of the first features observed is the species fitness, which describes the reproductive success or their ability to leave to their successive generations the most copies of their genotype. When different species that were recently divided into 2, by geographic isolation, for instance, usually there is no genetic compatibility, and if its possible to produce offspring, there might be some development issues like infertility.
The limitations of population dynamics simulation in predicting the changes that may occur due to climate change is that arctic seals can adapt to these climatic conditions or migrate.
<h3>What is population dynamics?</h3>
Population dynamics is the part of ecology that studies the variations in the occurrence of individuals of the same species (population) and seeks to define the cause of these variations.
Example: with the hunting of alligators, there is an increase in the population of piranhas, thus resulting in a variation of occurrence.
With this information, we can conclude that the limitations of population dynamics simulation in predicting the changes that may occur due to climate change is that arctic seals can adapt to these climatic conditions or migrate.

Question 1
The farther apart <span>two genes are located on a chromosome, </span>less likely they are to be inherited together
Question 2
Codominant alleles assort independently.
<span>Ozone is simply a molecule consisting of 3 oxygen atoms, which reacts strongly with other molecules. Ozone is created in the stratosphere when high energy uv radiation causes on O2 molecule to split. The free oxygen atoms collide and react with other O2 molecules to form O3.</span>
Production is highest where the solar uv is the greatest eg near the tropics, but once created, the ozone is then circulated towards the poles by the atmosphere. The amount of ozone in the stratosphere can vary with location, season and even day to day climatic conditions.
<span>The process of ozone creation is what makes the O3 in the atmosphere very effective at shielding the Earth from harmful uv radiation, which can cause many biological problems, such as skin cancer. However, due to its high reactivity, the uv found in the tropospher at ground level can aslo be dangerous as a toxic pollutant which is harmful to plants and lung tissue, and is a major cause of smog.</span>
