What period are you in? 1 2 4 5 6 7 8 Matching Match the term with the correct definition Heterozygous two different alleles, a hybrid (Tt) Heredity The passing of characteristics from parent to offspring Genotype The type of genes or alleles present in an organism Dominant The type of gene that always shows even in the presence of a recessive allele Trait Different forms of the same gene (EX: Tall vs. Short) One parent is heterozygous for their brown eyes while the other is homozygous for blue. Complete the cross and find the offspring. Mother/ Father B b Bb bb Bb bb What are the chances that the parents will have a child with blue eyes? For each genotype, indicate whether it is heterozygous (HE) or homozygous (HO) Genotype HE AA HO Ee HE Hh HE LL HO bb HO Qq HE Round seeds are dominant to wrinkled. Genotype Phenotype RR round Rr round rr wrinkled Genotype practice - for each of the phenotypes, list the genotype Straight hair is dominant to curly. (use "R" and "r") phenotype genotype Straight (homozygous) RR Straight (heterozygous) Rr Curly rr Tail spikes are dominant to plain (us "T" and "t") Phenotype Gentotype Pointed (homozygous) TT Pointed (heterozygous) Tt Round tt
