Design a Bird (VCE SSCE Biology): Flashcards

Genetic makeup - specific combination of alleles

Physical characteristic resulting from genotype

Neither allele dominant; heterozygous shows blended phenotype

Males are ZZ; females are ZW

Cross tracking single trait using 2×2 Punnett square

Cross tracking two traits using 4×4 Punnett square (16 combos)

Genes on different chromosomes inherited independently

Genes on Z chromosome; males have 2 copies, females have 1
