The passage of traits from parents to offspring.
Different forms of a gene, wich produce variations in a genetically inherited trait.
The study of how traits are inherited through the actions of alleles.
An offspring that was given different genetic information for a trait from each parent. Ex. Tt, Dd,Ff [also called HETEROZYGOUS]
Describes trait thai is covered over, or dominates, another form of that triat[ and shows it's specific trait even if only one parent passes the gene to it's offspring].
Describes a trait that is covered over, or dominated , by another form of that trait and seems to disappear [except when both parents pass that gene to their offspring].
A tool to predict the probabillity of certain traits in offspring that shows the different ways alleles can combine.
An organism genetic makeup, expressed in uppercase and lowercase letters for dominant and recessive alleles. Ex. TT, tt, Tt, DD,dd Dd.
An outward physical appearence or behavior of an organism, expressed in words. Ex. Brown hair, green eyes, red flower, tall horse.
Describes an organism with two alleles that are the same for a trait- one from mom and the other dad are the same. Ex, TT, tt.
Describes an organism with two different alleles for a trait- one from mom and a different one from dad. Ex. tt.
Genes that are altered or copied incorrectly.
