Back to the Game Board 10 Point Question genes Factors that control traits are called Back to the Game Board 20 Point Question purebred Mendel called a plant that had two identical alleles this ________ Back to the Game Board 30 Point Question ¾ or 75% What did Mendel predict was the probability of producing a tall plant from a cross of two hybrid tall pea plants? Back to the Game Board 40 Point Question Alleles The different forms of a gene are called ___________ Back to the Game Board 10 Point Question different A heterozygous organism has two ____________ alleles for a trait. Back to the Game Board 20 Point Question Tall If purebred short pea plants are crossed with purebred tall pea plants, all of the offspring will be ______________ Back to the Game Board 30 Point Question Two dominant alleles What does the notation of two capital letters together mean to geneticists? An example is DD. Back to the Game Board 40 Point Question Probability The likelihood that that a particular event will occur is known as ______________ Back to the Game Board 10 Point Question True True or False: A pea plant that is heterozygous for tall stems has the alleles Tt. Back to the Game Board 20 Point Question ¼ or 25% In Mendel’s experiments, what portion of the plants in the F2 generation had a trait that had been absent in the F1 generation? A. None B. ¼ or 25% C. Half or 50% D. ¾ or 75% Back to the Game Board 30 Point Question 100% will have black fur (Bb) If a homozygous black guinea pig (BB) is crossed with a homozygous white guinea pig (bb), what is the probability that the offspring will have black fur? Back to the Game Board 40 Point Question False, (offspring) True or False: A Punnett square shows all the possible combinations of alleles in parents Back to the Game Board 10 Point Question Punnett Square A __________ shows all of the possible allele combinations of a genetic cross Back to the Game Board 20 Point Question D. One dominant/one recessive A. B. C. D. What does the notation Tt mean to geneticists? Two dominant alleles Two recessive alleles At least one recessive allele Back to the Game Board One dominant allele and one recessive allele 30 Point Question C neither dominant nor recessive What does codominance mean in genetics? Both alleles are dominant B. Both alleles are dominant and recessive C. The alleles are neither dominant nor recessive A. Back to the Game Board 40 Point Question B. Phenotype A. B. C. An organism’s physical appearance is its Genotype Phenotype Codominance 10 Point Question Back to the Game Board A. Genetic Makeup An organism’s genotype is its A. B. C. D. Genetic makeup Feather color Physical appearance Stem height Back to the Game Board 20 Point Question False- only probability True or False Punnett squares predict the exact outcome of the offspring of a genetic cross Back to the Game Board 30 Point Question Photosynthesis The process where plants take in water and carbon dioxide to make glucose and oxygen is known as? Back to the Game Board 40 Point Question Draw a Punnett square for a cross between a homozygous short pea plant and a heterozygous tall pea plant Predict the possibility of getting a tall pea plant. Punnett square should contain tt and Tt and the possibility of getting a tall pea plant is 50%
