1) name mendel’s two laws that explain why brothers and sisters are not identical even though they come from the same parents? law of law of * * * * * * * * * * * * * when 2 alleles blend to show an intermediate phenotype (like crossing red and white flowered plants and producing pink flowered offspring) the gene is said to be incompletely dominant. 2) if a trait shows incomplete dominance which genotype must an organism have to show the intermediate blended phenotype? a. pure dominant b. pure recessive c. heterozygous d. homozygous recessive 3) which trait in reebops appears to blend and show incomplete dominance? 4) if pea plants showed incomplete dominance for height, what would a plant look like that had both a tall allele and a short allele? * * * * * * * * * * * * * when neither of two alleles is dominant over the other, they don’t blend but both appear together at the same time (like a and b blood type alleles). the gene is said to be codominant. 5) which trait in reebops appears to be codominant? 6) why do you think so? 7) if pea plants showed codominance for flower color, what would a plant look like that had both a red flowered allele and a white flowered allele? circle the correct answer in each pair. 8) a reebop with the genotype tt is (homozygous or heterozygous) for tail genes. 9) a reebop with the genotype ll is (homozygous or heterozygous) for leg genes. 10) a reebop with the genotype ee is (pure or hybrid) for eye genes. 11) a reebop with the genotype aa is (pure or hybrid) for antenna genes. 12) what has to be true about the reebop parents that show a dominant allele for a trait, but have a baby that shows the recessive trait? a. both parents are homozygous for the trait b. both parents are heterozygous for the trait c. both parents are pure for the trait d. impossible; dominant looking parents can’t have a recessive looking offspring
