CAIE IGCSE Biology 17.4.6 Heterozygous as having two different
Practise identifying heterozygous genotypes from inheritance diagrams and writing allele symbols for organisms with two different alleles.
How this is tested
- identify heterozygous plants or offspring from a genetic diagram
- state the genotype of an organism with two different alleles for a gene
