Trait - ✔️✔️Characteristic that is inherited; can be either dominant or recessive.
P Generation - ✔️✔️The true-breeding (homozygous) parent individuals from which F1 hybrid
offspring are derived in studies of inheritance; P stands for "parental."
F1 generation - ✔️✔️The first filial, hybrid (heterozygous) offspring arising from a parental (P
generation) cross.
F2 generation - ✔️✔️The offspring resulting from interbreeding (or self-pollination) of the hybrid
FF1 generation.
Allele - ✔️✔️Any of the alternative versions of a gene that may produce distinguishable
phenotypic effects.
Dominant Allele - ✔️✔️An allele that is fully expressed in the phenotype of a heterozygote. Only
need 1 copy of dominant allele to show dominant trait.
Recessive Allele - ✔️✔️An allele whose phenotypic effect is not observed in a heterozygote - it is
"masked" or hidden. Need 2 copies of recessive allele to show recessive trait.
Genotype - ✔️✔️The genetic makeup, or set of alleles, of an organism. (Ex: PP, Pp or pp)
Phenotype - ✔️✔️The EXPRESSED/observable physical and physiological traits of an organism,
which are determined by its genetic makeup.
Punnett Square - ✔️✔️A diagram used in the study of inheritance to show the predicted genotypic
results of random fertilization in genetic crosses between individuals of known genotype.
Homozygous - ✔️✔️Having two identical alleles for a given gene; dominant (RR) or recessive (rr)
Heterozygous - ✔️✔️Having two different alleles for a given gene (Rr)
Dihybrid Cross - ✔️✔️A Punnett Square that is used to cross 2 different traits, contains 16 square.
Hybrid - ✔️✔️see heterozygous, An organism that has two different alleles for a trait
Purebred (aka: true-breeding) - ✔️✔️see homozygous, An organism that always produces
offspring with the same form of a trait as the parent
genetics - ✔️✔️Scientific study of heredity
heredity - ✔️✔️Passing of traits from parents to offspring
