Recessive, as in recessive genes, refers to an inherited characteristic or trait that is expressed only when two copies of the gene responsible for it are present.

Do autosomes have lethal recessive genes?
Yes. Autosomes CAN have lethal recessive genes, but that does not mean they always contain recessive mutations.
What genes does a homozygous short pea plant always have?
Recessive genes
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.
Why aren't somatic mutations passed on to the next generation?
most genes mutations are recessive, and since most organisms have two of every genes, the normal genes will dominate the recessive genes.
Why do the recessive genes do not disappear from the population?
The reason for recessive genes not disappearing is because there is always a different gene that you can pass on through your offspring
Do autosomes have lethal recessive genes?
Yes. Autosomes CAN have lethal recessive genes, but that does not mean they always contain recessive mutations.
Do dominant genes affect recessive genes?
The dominant genes take over, and then the recessive genes hide away
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.
What genes does a homozygous short pea plant always have?
Recessive genes
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.
Traits determined by recessive genes located on the x chromosomes are said to be?
Some traits are determined by recessive genes on the X chromosomes. Many times these are genetic disorders and are called recessive genes.
The weaker of two genes is called what?
dominant
What does pure dominant mean?
Pure dominant = two dominant genes that make a "pure dominant" trait. Pure Recessive = two recessive genes that make a "pure recessive" trait.
How do combinations of genes occur?
through dominate and recessive genes
Why aren't somatic mutations passed on to the next generation?
most genes mutations are recessive, and since most organisms have two of every genes, the normal genes will dominate the recessive genes.
What does recessive albinism mean?
An Autosomal recessive pattern is one in which certain genes of the X sex chromosome are turned off, autosomal is in reference to the X chromosome and the fact that the genes are turned off is indicated by the recessive. So in the case of Albinism the pigmentation genes in the X chromosome are turned off causing the various side effects.
Are freckles recessive genes?
Freckles are not determined by a single recessive gene. They are the result of a combination of genetics, particularly the presence of certain variations in the MC1R gene, and exposure to sunlight. The inheritance of freckles can vary depending on the specific genetic traits passed down from parents.
