i belive that the definition of recessive and dominant laws is from a genes with a type of Rr R:is for the type of ao it is the law of dominant ang the r: is unless type of oo and theres no type unless thee oo it is from the laws of the recessiveness

Definition of dominance in genetics?
On any given locus, there are different possible forms of a gene, called "alleles." There is a dominant allele for each gene, often expressed by a capital letter. Recessive genes are frequently denoted with a minuscule letter. For example, "R" would represent a dominant allele and "r" a recessive one. Every individual has two alleles each gene (for example, Rr, RR, or rr); in this pair, a dominant allele is expressed if it is present, regardless of what other allele is carried. Recessive alleles, conversely, will only be expressed if there are two of them -- rr, in this case. There may be more than two alleles in each set, but they all follow the rule of dominance. For example, ra might be dominant to rb, which might be dominant to r. In some cases, dominance is incomplete. This means that individuals heterozygous for a certain gene -- meaning both the alleles are different, i.e. Rr, as opposed to the same (homozygous) -- will express a different trait than those homozygous recessive (rr) or dominant (RR).
How do you spell recesive?
The correct spelling is recessive (refers to non-dominant gene).
Another word for a heterozygous genotype?
A Heterozygous genotype means an organism that has both the dominant and the recessive gene.
What is the opposite of codominance?
The opposite of codominance would be ordinary dominance (the expression of a dominant gene over a recessive one).
What are the opposites of dominant?
in biology, the opposite is recessive in sexual behavior, the opposite is submissive in some terms, the opposite is rare
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.
How do dominant and recessive genes work?
explain how dominant genes work
What is the difference between homzyguos and heterozyous?
Homozygous recessive: is when the genes are both recessive Homozygous dominant: is when the genes are both dominant (traits show) Heterozygous dominant: is when one gene is dominant and one is recessive (traits show) Heterozygous recessive: is the same as heterozygous dominant but the dominant genes are inactive
The most powerful genes are said to be?
Dominant, as in dominant and recessive (weaker) genes.
The weaker of two genes is called what?
dominant
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.
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.
Are freckles dominant recessive or dominant dominant?
dominant genes for freckles
Can recessive genes become dominant?
Yes
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.
Genes that are only seen when paired with a recessive gene?
if u have a recessive gene with a recessive gene then u can see the recessive gene but if you have a dominant gene with a recessive gene you can only see the dominant gene hope that helps:)
