F1 hybrid (round) x pure wrinkled (do it yourself: ss x ss 50% wrinkled, 50% round. Genotype: the genes themselves (smooth vs. wrinkly) Phenotype: the outward expression of those genes. Allele: variant of a gene, for example: wrinkled allele and round allele of the seed-shape gene; alternative versions of the same gene. Homozygous: two matching alleles (ss and ss) Two parents are homozygous for different versions of a trait (aa and aa). Assuming the trait exhibits complete dominance, their offspring: Have a mix of phenotypes 3 dominant for every 1 recessive. Have a mix of genotypes: approximately 3 recessive for every 1 dominant. Will be half homozygotes and half heterozygotes. Chromosome: linear aggregation of genes (mostly in nucleus)
