Sometimes there are more dominant genes than other genes so you will notice them earlier, but generally not more common. Genetic mutations are passed on by the parents so that the child can continue it. It more common that the parent can obtain the mutation and it is very common that the mutation will be passed on to the

The terms recessive and dominant have nothing to do with frequency of occurrence. Many people think that "dominant genes" equates to being the normal, or most common gene for a particular trait.

Instead, the terms refer to what trait shows up from a particular allele (gene pair). A dominant gene is "dominant" because it shows up if it's present, no matter what. Recessive genes only show up if both genes in the pair are the recessive type.

Traits that are considered "normal", but are recessive include things such as normal growth. The gene for dwarfism is dominant. That just means that this particular gene mutation works in a way that it shows up if it's present at all, and has no correlation with it's rate of occurrence.

Some mutations are inherited because they are in gamete cells. Mutations that are not inherited are formed during the lifetime of the parent organism.

What is the difference between dominant and recessive gene?

There are no such things as dominant and recessive genes. There are only dominant and recessive alleles. Dominant alleles are parts of a gene that present its features over the recessive allele, which is the one that is always masked by the dominant allele. The recessive allele's trait only shows if both of the alleles in a trait are recessive.

Which genes are dominant and which are recessive?

Dominant genes are always expressed in preference to recessive genes in cased where both genes are present.

Recessive allele is more common or dominant allele?

Not necessarily. I think the dominant genes are more common, but there are lot of exceptions out there. For example, having six fingers in humans is a dominant gene, but it isn't all that common.

Yes. Autosomes CAN have lethal recessive genes, but that does not mean they always contain recessive mutations.

Genes that are only seen when paired with a recessive gene?

If an animal with 2 dominant genes for a trait has offspring with an animal with 2 recessive genes for same trait their offspring can only have what?

Their offspring will have dominant genes. However, if these offspring have offspring with an amimal with recessive genes, the recessive genes will show up.

Is it true that all genes show simple patterns of dominant and recessive allleles?

No, it is not true that all genes show simple patterns of dominant and recessive alleles. When Mendel did his studies on peas, he was lucky in that the genes he worked with showed those patterns. Many genes are much more complex and often involve more than one gene. Many genes show intermediate expressions between dominant and recessive.

Some traits are determined by recessive genes on the X chromosomes. Many times these are genetic disorders and are called recessive genes.
