9. Make a pedigree for each of the following situations. For each individual, write the individual's genotype (when possible) next to the individual's symbol (e.g. O xty, I Gg): a. Two parents do not have cystic fibrosis and they have a daughter with cystic fibrosis and a son who does not have cystic fibrosis. The daughter grows up and she mates with a male who does not have cystic fibrosis. Their only child is a boy and he has cystic fibrosis. b. A man with hemophilia mates with a female without hemophilia. They have one son and one daughter. The daughter has hemophilia and the son does not have hemophilia. The son grows up, and he marries and mates with a female. Their only child is a boy, and he has hemophilia.
Create monohybrid crosses from the following information: 33. Homozygous monkey toes with non-monkey toes. 34. What are the genotypes and phenotypes of number 33? 35. Both heterozygous brown eyes. 36. What are the genotypes and phenotypes of number 35? 37. Heterozygous large size with small size. 38. What are the genotypes and phenotypes of number 37?
3. Short-tailed pup distribution. In mice, the dominant T allele results in a short tail. Homozygous T/T genotype is lethal, which means mouse embryos with this genotype die before they are born. Homozygous t/t is normal, with normal tail. A cross between two short-tailed mice produces a litter of 5 pups. a). What are the genotype(s) of the two short-tailed mice used in the cross? b). What are the possible genotypes and phenotypes of the 5 pups? What are their perspective ratio?
1,Show the cross between two people with Type AB blood. What is the genotypic and phenotypic outcome of such a cross? 2. Incomplete dominance = If a Red (RR) and White flower (rr) were crossbred, resulting in 100% Rr, what phenotype(s) would been seen according to the rules of IN-complete dominance? 3. Two parents think their baby was switched at the hospital. Its 1968, so DNA fingerprinting technology does not exist yet. The mother has blood type “O,” the father has blood type “AB,” and the baby has blood type “B.” Mother’s genotype: _______ Father’s genotype: _______ Baby’s genotype: ______ or _______ Was the baby switched? ____________________________________________________
3. Determine the genotypes, phenotypes, genotypic ratio, and the phenotypic ratio of the following tri-hybrid cross. A male having genotype aaBBCC mates with a female having genotype AaBbCc. Wherein: (A) (B) (C) is Straight hair and (a) is curly hair is Tall and (b) is short is Long nose and (c) is flat nose
1. In pea plants, yellow color (Y) is dominant over green color (y). A yellow-colored pea plant is crossed with a green-colored pea plant. Half of their offspring is yellow-colored while the other half is green-colored.What is the genotype of the yellow-colored parent? YY O Yy yy The genotype cannot be determined. 2. A scientist discovered an unknown organism in a tropical rainforest. The organism has been identified to possess the following characteristics: (1) multicellular at some point of its life cycle; (2) feeds on decaying organic matter; and (3) has a cell wall made of chitin.Which Kingdom does the unknown organism likely belong to? Kingdom Animalia Kingdom Plantae Kingdom Fungi Kingdom Protista 3. Which statement about ferns is TRUE? Ferns are unicellular organisms. Ferns are nonvascular plants. O Ferns have spores as reproductive structures. Ferns are capable of secondary growth.
In guinea pigs, black hair is dominant over white hair. If a homozygous black guinea pig (father) were crossed with a homozygous white guinea pig (mother), the first generation of offspring would be all black.Match the mother's and father's genotypes and phenotypes to their correct description. 1. mother's phenotype 2. father's phenotype 3. father's genotype 4. mother's genotype a. black b. HH c. white d. hh
Hemophilia is caused by an x-linked recessive allele. Make a cross between a hemophilic Father and a non-hemophilic Mother whose Father had hemophilia. 1. P1: 2: Punnett Square: Interpretations Female: 3. GR: 4. G% 5. PR: 6. P%: Male: 7. GR (Genotype Ratio): 8. G% 9. PR (Phenotype Ratio): 10. P%:

1. A pure line Brown coat goat is crossed with pure line White coat goat. Consider the Brown coat is dominant over white coat. a. What is the result (F1) of this cross? b. What is the result when 2 F1 hybrid from (a) is crossed? Give the phenotype, genotype and their ratio. Make sure the phenotype and genotype were aligned with its ratio.
1. While hiking your find a wild growing pea plant with purple flowers. You know that purple pea flowers are dominant to white pea flowers, but from looking at the plant, you cannot be certain if it is homozygous dominant or heterozygous. Explain the cross you could set up to determine the genotype of the wild pea plant and which results would indicate it is heterozygous versus homozygous. 2. Using skin color as an example of a multifactorial trait, explain why skin color produces a wide range of possible phenotypes within the human population.
