Dominant genes are shown for example as T recessive genes are shown as t if there is a dominant and recessive gene (Tt) then your child will get the dominant one this is called heterozygous. Meaning that they have two different genes for a trait such as curly hair and straight hair. There is also being homozygous (TT or tt) the only way your child could recieve a recessive gene such as left handednes, is if the two parents were carrying a recessive gene along with their dominant one or if they both were carrying two reccesive genes. the childs probable genotype can be explaind a lot better with a Punnet Square. I hope this wasn't too confusing.:-)
Homozygous dominant for two dominant genes or homozygous recessive for two recessive genes.
Recessive genes do not become dominant. Dominant genes mask the expression of recessive genes in the presence of both alleles. However, if a recessive gene is selected for over time through breeding, it can become more prevalent in a population.
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.
In genetic inheritance, dominant genes are versions of genes that are expressed over recessive genes. Dominant genes mask the effects of recessive genes when they are present together in an individual's genetic makeup.
Hair color is determined by genes inherited from parents. Dominant genes for hair color will be expressed over recessive genes, resulting in the dominant color being displayed. If both parents pass on recessive genes, the recessive color will be seen.
The dominant genes take over, and then the recessive genes hide away
Dominant genes are always expressed in preference to recessive genes in cased where both genes are present.
Homozygous dominant for two dominant genes or homozygous recessive for two recessive genes.

Their offspring will have dominant genes. However, if these offspring have offspring with an amimal with recessive genes, the recessive genes will show up.
The weaker of two genes is called the recessive gene. In the presence of a dominant gene, the recessive gene is not expressed in the organism's phenotype.

Hair color is determined by genes inherited from parents. Dominant genes for hair color will be expressed over recessive genes, resulting in the dominant color being displayed. If both parents pass on recessive genes, the recessive color will be seen.
Examples of dominant genes include brown eyes and attached earlobes, where the dominant allele will be expressed over its recessive counterpart. Recessive genes include blue eyes and detached earlobes, which will only be expressed when an individual has two copies of the recessive allele.
Two recessive alleles can not take over a dominant allele because there are only two alleles in a pair. This can only happen if there is a mutation because the dominant always takes over the recessive.
