Once again weâre looking at flying out to see friends over a weekend this spring. And once again it looks like the lowest cost option is Spirit Airlines.

A recessive trait is the phenotype that is seen only when a homozygous recessive genotype for the trait of interest is present. This means that an individual must have two recessive alleles for the gene that determines this trait of interest.

(In genetic terms, a dominant trait is one that is phenotypically expressed in heterozygotes). A dominant trait is opposed to a recessive trait which is expressed only when two copies of the gene are present. (In genetic terms, a recessive trait is one that is phenotypically expressed only in homozygotes). Polycystic kidney disease (of adult onset).
