Part A: VocabularyMatch the definitions to the terms:Genotypes made of the same alleles - D. HomozygousDifferent forms of genes for a single trait - A. AllelesGene that is always expressed - B. DominantGene that is expressed only in the homozygous state - E. RecessiveGenotypes made of two different alleles - C. Heterozygous6. Homozygous dominant: These genotypes must have two dominant alleles. Examples are: AA, KK, TT7. Homozygous recessive: These genotypes must have two recessive alleles. Examples are: ee, qq, ww8. Genotypes in which dominant gene must show: These genotypes have at least one dominant allele. Examples are: AA, Dd, EE, Jj9. Genotypes in which recessive gene must show: These genotypes must be homozygous recessive. Examples are: aa, rrPart B: Punnett Squares10. You are asked to circle the correct Punnett squares. Here are the correct ones:Dd ddAA aaDd Dd11. The letters on the outside of the Punnett square stand for the alleles provided by each parent.12. The letters on the inside of the Punnett square represent the possible genotypes of the offspring.
