cross pollination - pollen from one plant fertilizes the ovule of a flower on another plant., self pollinating plants - Plants have both male and female reproductive structures. So, pollen from one flower can fertilize the ovule of the same flower., true breeding - This plant has 2 dominant alleles. When a true-breeding plant self pollinates, all of the offspring will have the same trait as the parent., dominant - This is the trait that appeared over the recessive trait., recessive - The trait that seemed to fade into the background and gets masked by the dominant trait., hybrid trait - This trait is also known as a heterozygous trait, and is the pairing of a dominant and recessive allele., homozygous - The presence of two identical alleles for a particular gene. Ex. BB, bb, heterozygous - This trait is also known as a hybrid trait, and is the pairing of a dominant and recessive allele. Ex. Bb., Punnett Square - A tool used to organize all the possible genotype combinations of offspring from particular parents., genotype - The combination of inherited alleles together form an organism’s genotype. Think letters., phenotype - An organism’s physical appearance. , genes - The instructions for an inherited trait., alleles - The different forms (often dominant and recessive) of a gene., incomplete dominance - Researchers have found that sometimes one trait is not completely dominant over another., probability - The mathematical chance that something will happen., One Gene, Many Traits - Sometimes one gene influences more than one trait., Many Genes, One Trait - Some traits, such as the color of your skin, hair, and eyes, are the result of several genes acting together.,
