Mendelian Inheritance Latest 2023 Rated A+

Mendelian Inheritance Latest 2023 Rated A+ Allele One of the two *alternative forms of a gene* found in the same place on homologous chromosomes. Dominant Inheritance A pattern of inheritance in which the effect of *one allele is completely expressed* within a homozygous and heterozygous genotype. Genotype The* genetic composition of an organism* with reference to a single trait, a set of traits, or the entire complement of traits of an organism. Heredity The process in which *genetic material is passed from parents to their offspring.* Phenotype The *observable expression of a genotype.* Recessive Inheritance A pattern of inheritance in which the effect of *one allele is only expressed within a homozygous genotype*. In a *heterozygous* condition with a dominant allele, it is *not expressed* in the phenotype. Homozygous (pure) A *genotype* in which the individual has *two of the same type of allele* (either both dominant or both recessive). Heterozygous (hybrid) A *genotype* in which the individual has *two different forms of alleles* (one dominant and one recessive). Punnett square A *diagram* that is used to *predict an outcome* of a particular *cross or breeding experiment*. Homologous Chromsomes A *pair of chromosomes* that carry alleles for the *same traits*. One is inherited from each parent (maternal and paternal). Trait A specific *characteristic of an organism*, determined by genes, the environment, or both. Its genetic contribution is a *genotype*, and its outward expression is a *phenotype*. Monohybrid A cross representing the *inheritance pattern of a single trait* in an organism. Dihybrid A cross representing the *inheritance pattern of two traits that are linked* in an organism. Mendelian Inheritance A form of inheritance in which a trait is expressed in dominant and recessive forms. P1 Generation The *parent generation* in Mendel's experiments. The *parents were Homozygous (Pure) Dominant and Recessive*, respectively. F1 Generation The *first generation of offspring* in Mendel's experiments. All of the offspring were *Heterozygous* (Hybrid), resulting in *no recessive traits expressing*. F2 Generation The *second generation of offspring* in Mendel's experiments. *One out of four offspring expressed recessive traits* (Homozygous Recessive).
