ANTH 1200 Lecture Notes - Lecture 3: Gregor Mendel, Zygosity, Meiosis
Document Summary
A sequence of dna on a chromosome that codes for a specific protein. Allel: one or more alternative forms of a gene. The combination of alleles for a given name. Two alleles are inherited for any given gene one from each parent. During menosis only one of the two will be present in each oven/sperm. The inheritance of one trait does not affect the inheritance of other fruits. All combinations of fruits are possible because of homologous pair separation and recombination during meiosis. Full number of chromosomes restored after fertilization esexist. When alleles are heterozygos, the dominant one will be expressed in the phenotype, but the recessive will not. Zygote: cell that results from sperm fertilizing orn. Heterozygous: refers to the condition in which a pair of alleles at a single locks on a homologous chromozome are different. Refers to the condition in which a pair of alleles at a single locks on a homologous chromozome are the same.
