Not true breeding for a specific hereditary character Plants may be heterozygous for some characteristics and homozygous for others
Having such a mixture of heritable factors in a plant's chromosomes that they show great variation of type when grown from a seed One very good reason we do most of our plants from cuttings
The two genes in a pair are different For example, one mackerel tabby gene (dominant) and one classic tabby gene (recessive) The individual will display the characteristics of the dominant gene, but can pass on the characteristics of the recessive gene to offspring
having two different genes for a given trait Such a snake with one recessive, mutated gene looks normal, but it can pass the gene on through breeding A heterozygous snake with one (co)dominant, mutated gene looks different than a wild-type because of that gene
having different alleles at the same locus on a chromosome; a recessive and a dominant are paired (so the dominant trait is observed)
{s} containing a dissimilar pair of genes for any hereditary characteristic (Biology)
Having different, or contrasting, alleles on the two parental chromosomes at a given locus
in this genetic context, referring to individuals that have two different alleles for a particular gene
