Dominant and Recessive Dominance Table 3

Alleles sequence of DNA any of several forms of a gene determine the genotype (genetic constitution of an organism or a group of organisms) of their host organism

Dominant Alleles expressed over the recessive allele represented by capital letters determines the phenotype (any observable characteristic of an organism) of an organism

Recessive Alleles hidden by it's dominant partner but still present in heterozygous individuals (an organism that has two copies of the same allele) only expressed when there are two recessive alleles represented by lower case letters

Genes a unit of heredity in a living organism a region of DNA that controls a hereditary characteristic carries biological information in a form that must be copied and transmitted from each cell to all its progeny

Dominant Genes causes a person to have a particular physical characteristic when written in a genotype is always written before the recessive gene in a heterozygous pair (two different forms of a particular gene) a person only needs to inherit one copy of the gene for the trait to be expressed

Recessive Genes can only be expressed in homozygous (aa) individuals (an organism that has two copies of the same allele) has its expression masked in the presence of a dominant gene a person needs to inherit two copies of the gene for the trait to be expressed

Traits a distinguishing characteristic or quality come from our genes, which are unique to each person

Dominant Traits will manifest when only one copy of the gene is present will be possessed as long as you inherit it from either of your parents

Recessive Traits can be carried in a person's genes without appearing in that person will be possessed only if you inherit it from both parents
