2.1 Glossary
Starting Term Defination Related Term Character < Genotype > < Genotype of an organism is the gene combination it possesses. Genotype of phenotypically yellow seeded F1 may be YY or Yy.> < Phenotype > < Phenotype refers to the observable attributes of an organism. Plants with either of the two genotypes Yy or Yy are phenotypically yellow seeded.> < Homozygote > < A plant with a pair of identical alleles is called as Homozygote (Y/Y or y/y).> < Heterozygote > < a plant in which the allele of the pair differ is called as heterozygote (Y/y).> < locus > < A locus (plural: loci) is the location of a gene on a chromosome. The gene for red flowers and the gene for white flowers are two different alleles at the same locus.>
