Dominant genes: the characteristic it controls will be displayed. Recessive genes: the characteristic it controls will not be displayed, unless the partner gene received from the other parent is recessive as well. Polygenic transmission: when a number of gene pairs combine their influences to create a single phenotype trait.

This type of research is looking very important for the future: zygote: formed from an egg cell and sperm cell, alleles: alternate forms of a gene that produce different characteristics. Genetic engineering the edge of creation: recombinant dna procedures: using certain enzymes to cut the long threadlike molecules of genetic.
