inherited traits - That two factors control each inherited trait from one parent, what is a dominant trait? - one that is expressed when only one copy of the responsible allele (a version of a gene) is present, effectively masking the effect of any other allele (recessive) for the same trait, How do dominant and recessive factors interact? - One dominant factor will block a recessive ractor, so the recessive factor will only appear if the offspring has two recessive factors, recessive trait - a characteristic that is only expressed when an individual has two copies of the recessive allele, gene - the basic unit of heredity, a segment of DNA that contains the instructions for making a specific protein or RNA molecule, passed down from parents to offspring., allele - a variant form of a gene, one of two or more versions of a DNA sequence at a specific location (locus) on a chromosome, inherited from each parent, that can determine traits or characteristics., phenotype - the observable characteristics or traits of an organism, resulting from the interaction of its genotype with the environment, Genotype - an organism's complete set of genes or genetic makeup, specifically the combination of alleles (versions of a gene) an individual carries for a particular trait., homozygous - having two identical alleles (versions) of a gene, inherited from each parent, for a specific trait, heterozygous - having two different versions (alleles) of a gene, one inherited from each parent, at a specific location (locus) on a chromosome., punnett square - a diagram that helps predict the possible genotypes of offspring from a cross between two parents, Pedigree - a family history diagram, an animal's genetic background, or the history of something.,
