genetics and alleles and chromosomes

TermDefinition

alleles one of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome.
Heterozygous having two different alleles of a particular gene or genes.
homozygous Homozygous is a word that refers to a particular gene that has identical alleles on both homologous chromosomes
hybrid the offspring of two plants or animals of different species or varieties,
punnet squares The Punnett square is a square diagram that is used to predict the genotypes of a particular cross or breeding experiment.
phenotype The phenotype of an organism is the composite of the organism's observable characteristics or traits
genotype The genotype is the part of the genetic makeup of a cell, and therefore of any individual,
recessive allele A recessive allele is a variety of genetic code that does not create a phenotype if a dominant allele is present.
dominant allele Dominance in genetics is a relationship between alleles of one gene, in which the effect on phenotype of one allele masks the contribution of a second allele at the same locus.
