Paper 1, Paper 2
The combination of alleles an organism has, either for a particular gene or more generally.
Revise: Alleles and inheritance patternsThe combination is its genotype; the resulting observable characteristic is its phenotype. Different genotypes can sometimes produce the same phenotype.
The combination of alleles an organism has.
Label ratios clearly: a genotype ratio and a phenotype ratio can be different.
A dominant phenotype does not uniquely identify a genotype: the individual could be homozygous dominant or heterozygous.
Put one allele from each parent into each Punnett-square cell: gametes carry one allele, not the parent's complete genotype.
