How are heterozygotes different from homozygotes?
| May 30, 2020 | Education
1) Heterozygosity – the content in the body cells of different genes (dominant and recessive) of a given allelic pair (Aa). The dominant gene manifests itself in the heterozygous phenotype.
2) Homozygosity – the content of identical genes of a given allelic pair by a cell (AA – homozygous for the dominant gene, aa – homozygous for the recessive gene). In a recessive homozygote, in the absence of a dominant gene, the recessive gene is phenotypically manifested.
