Genotype: Is the letters we use to represent the trait on the chromosome (Examples: TT, Tt, tt) Phenotype: Ist he trait or characteristic we 'see (Examples: Tall, Short) Homozygous Dominant: Genotype is dominant from both parent chromosomes/alleles (Example TT) Phenotype is the dominant allele = also known as purebred Homozygous Recessive: Genotype is recessive from both parent chromosomes/alleles (Example tt) Phenotype is the recessive allele = also known as purebred Heterozygous: Genotype is different--One is dominant allele and one is recessive allele (example (Tt)--Phenotype is always of dominant allele = also known as hybrid. R = round r= wrinkled T = tall + = short Y = yellow peas y = green peas P = purple flowers p = white flowers IN PEAS: %3D MAKING MONOHYBRID CROSSES: What is the genotype of a HOMOZYGOUS YELLOW SEED plant? = What is the genotype of A HOMÓZYGOUS GREEN SEED plant? = What is the genotype of a HETEROZYGOUS YELLOW plant? = Using the Punnet Square above, make a cross between a PURE YELLOW SEED parent and a PURE GREEN SEED parent.
