1. A method used to predict probable offspring for a given problem 2. A different form of a gene (the DNA for a trait), variant 3. Someone that has two different forms of a specific gene, one from each parent
1.The Punnett square is a useful tool for predicting the genotypes and phenotypes of offspring in a genetic cross involving Mendelian traits.
2.An allele is a variant form of a gene. Some genes have a variety of different forms, which are located at the same position, or genetic locus, on a chromosome. ... Alleles can also refer to minor DNA sequence variations between alleles that do not necessarily influence the gene's phenotype.
3.An allele is one of two or more versions of a gene. An individual inherits two alleles for each gene, one from each parent. If the two alleles are the same, the individual is homozygous for that gene. If the alleles are different, the individual is heterozygous.
