WebMar 26, 2024 · If you are crossing two parents that are 'true breeding' - meaning they each have homozygous traits (one has dominant traits, the other has recessive traits) - the F1 generation will typically be heterozygous (having a genotype that is heterozygous and a phenotype that is dominant). By definition the tester parent will have the genotype of aabb. WebAug 21, 2024 · Diploid organisms typically have two alleles for a trait. When allele pairs are the same, they are homozygous. When the alleles of a pair are heterozygous, the phenotype of one trait may be dominant and the other recessive. The dominant allele is expressed and the recessive allele is masked. This is known as complete genetic dominance. green team chittenango ny
