Match the following:Column IColumn IIA. Locus1. Genetic makeup of an organism.B. Homozygous2. Both the alleles of a gene are non-identical.C. Heterozygous3. Both the alleles of a gene are identical.D. Phenotype4. Position of gene on chromosome.E. Genotype5. Physical expression of gene.
A-4, B-3, C-2, D-5, E-1
The position of a gene on the chromosome is called locus. An organism in which both the alleles of a gene are identical is called a homozygote (the condition being homozygous). If the alleles are non-identical, the organism is a heterozygote (heterozygous condition). The physical expression of a gene is called phenotype and the genetic makeup is called genotype.
