What is it called when two parents give rise to offspring that have a unique set of genes?
sexual reproduction
Why is an egg a cell?
An egg cell is haploid because the offspring gets one set of chromosomes from its mother and one set from its father, making it diploid. Haploid means that the egg contains one set of chromosomes. When the egg joins with the sperm (which is also haploid) the two cells unite and create a diploid zygote. If your egg and sperm cells weren't haploid than the offspring would have to many sets of chromosomes and would not be able to develop correctly.
How germline mutation occur?
Everyone acquires some changes to their DNA during the course of their lives. These changes occur in a number of ways. Sometimes there are simple copying errors that are introduced when DNA replicates itself. (Every time a cell divides, all of its DNA is duplicated so that the each of the two resulting cells have a full set of DNA.) Other changes are introduced as a result of DNA damage through environmental agents including sunlight, cigarette smoke, and radiation. Our cells have built in mechanisms that catch and repair most of the changes that occur during DNA replication or from environmental damage. As we age, however, our DNA repair does not work as effectively and we accumulate changes in our DNA. Some of these changes occur in cells of the body - such as in skin cells as a result of sun exposure - but are not passed on to children. But other errors can occur in the DNA of cells that produce the eggs and sperm. These are called germline mutations and can be passed from parent to child. If a child inherits a germline mutation from their parents, every cell in their body will have this error in their DNA. Germline mutations are what cause diseases to run in families, and are responsible for the kind of hereditary diseases covered by Genetic Health.
What are the main principles of animal evolution?
Animal evolution is not a linear set of rules or stages, but rather a branching process. Main principles include that mutations occur in a species and are tested by the environment, and the successful mutations live long enough to be passed down to offspring and continue through the gene pool. This is Darwin's theory of natural selection.
Are mutations predictable?
No, they are random, This means that they occur in no set numerical order. So, though they can not be predicted it is certain, with the mistakes made in replication and other factors, that they will occur.
What determines the outcome of a mutation?
There are plenty of factors that can induce mutations. There are several harmful rays, such as X-rays and gamma rays, that can affect the DNA structure within gametes and that can cause mutations to occur. There are certain types of food that can also have the same affect. There are also genetic factors that can cause mutations. During Anaphase two where the DNA materials are splitting apart to form gametes, a process known as non-disjunction can occur where one of the gametes has an extra set of chromosome and the other has one or more less set of chromosomes.
Who is seth and nephthys children?
In Egyptian mythology, Set and Nephthys did not have children together. Set's consort was usually considered to be the goddess Nephthys, but they did not have any offspring together.

Why cross pollination produces more genetic variation in the offspring than self pollination produces?
Cross-pollination produces more genetic variation in offspring because it is a different set of DNA that is breeding with the parents DNA to produce the offspring (known as sexual reproduction). In asexual reproduction, the parent plant uses a clone DNA to self pollinate thus creating an exact copy of the parent. Asexual reproduction inhibits genetic variation because the offspring will never develop mutations that could help natural selection.

What is a rapid evolution of species that comes about by the mutation of a few genes?
An example of very rapid speciation could be the process of polyploidy, which is often observed in plants, but also known to occur in animals. This is the uncharacteristic (at least in that particular species) duplication of all chromosomes in offspring. Occasionally, such a whole-genome duplication can cause an inability to interbreed with organisms from the parental stock, meaning that speciation has occurred. This form of speciation would be almost impossible to occur in species of sexually reproducing animals, unless the same whole-genome duplication occurred more frequently, or the organism in question were able to self-fertilize (some hermaphrodite organisms may be able to do so).Of course any set of mutations that significantly alters the physiology of offspring without inhibiting its ability to reproduce could be categorized in the same way.
