1. Use the following information to answer the question: Parental cross is RrYy x RrYy Seed Shapes are R-round, r-wrinkled Seed colors are Y-yellow, y-green Based on the information given, what is the phenotype ratio of the offspring of this cross? 2. A pea plant heterozygous for height and seed color (TtYy) is crossed with a pea plant heterozygous for height but homozygous recessive for seed color (Ttyy). If 80 offspring are produced, how many are expected to be tall and have yellow seeds? 3. What is the chromosome theory of inheritance? How does this theory explain Mendel's results? 4. A cross between two organisms heterozygous for two different genes (AaBb) results in a 9:3:3:1 phenotype ratio among the offspring. Is the offspring's genotype ratio the same? Explain your answer.…

2. Show the cross and provide full justification in each case:a) An F1 x F1 self-fertilization gives a 9:7 phenotypic ratio in the F2. What phenotypic ratio would you expect if you test-crossed the F1? b) An F1 x F1 self-fertilization gives a 9:3:4 phenotypic ratio in the F2. What phenotypic ratio would you expect if you test-crossed the F1? c) An F1 x F1 self-fertilization gives a 15:1 phenotypic ratio in the F2. What phenotypic ratio would you expect if you test-crossed the F1?

1. Solve monohybrid and dihybrid cross genetic outcomes utilizing branch diagrams and/or Punnett squares. 2. Apply and demonstrate the law of segregation and law of independent assortment
Use a Punnett square to predict the offspring in a cross between a dwarf pea plant (homozygous recessive) and a tall pea plant (heterozygous). What is the phenotypic ratio of the offspring?
1-Show the results of a dihybrid cross for the F1 and F2 generation between P generation of a pea plant that is homozygous dominant for purple flower and yellow pea seed with another pea plant that is homozygous recessive for white flower and green pea seed. Clearly show the cross indicating BOTH genotype and phenotype for each generation. How many offspring in the F2 generation will have these phenotypes? 2-What is the probability of a woman who is a carrier for the blood disease hemophilia producing a son with hemophilia if she marries a man who does not have hemophilia? What is the probability of her daughters having hemophilia? Explain why the probability of getting this disease is different for sons versus daughters in this case. Your work should clearly indicated sex, genotype and phenotype (carrier or affected).
Could someone please help me with this grade 11 bio dihybrid cross problem in detail and how to solve this question, using a strategy? Assume that curly hair (C) is dominant to straight hair. Albinism (P ) is recessive to normal skin pigmentation. A woman who is heterozygous for curly hair and albinism has a child. The father is homozygous dominant for curly hair and has albinism. (a) Determine the possible phenotypes for their child. (double-crossing, Puneet square)(b) Calculate the four different probabilities of a child beingboth a male and of each phenotype.(c) What is the probability that the child will expressalbinism and have curly hair like his father?
3) A. How are the following proteins involved in cell division: condensing, cohesin, kinetochore complex, tubulin? B. Why does phenotype not always reveal genotype? C. How can Mendel's postulates of segregation and independent assortment be explained by meiosis? D. Explain the genotypic and phenotypic ratios predicted when performing a monohybrid and a dihybrid cross of heterozygotes? E. How can you use the product rule and sum rule to calculate the probability of a particular genotype resulting from crossing parents of specific genotypes?
Solve the following problem by listing the given genotypes, test crosses, and genotypic and phenotypic ratios. A plant with serrated leaf margins is crossed with a plant with smooth leaf margins, producing a plant with wavy leaf margins. What will be the phenotypic and genotypic ratios if a homozygous plant with serrated leaves is crossed with a plant with wavy leaves?

1. Construct a pedigree chart of the trait traced in the situation below.2. The pedigree chart must be constructed with the names and genotypes at the bottom of every individual in the chart.If it is autosomal: Always use the first letter of the dominant trait to represent the dominant allele. For example, if the dominant trait is red, so the allele R-red, while r-yellow. For example, if the person is homozygous dominant for curly hair, we write CC as his genotype. If sex-linked, do not forget to write the parents’ chromosomes (XX-female, XY-male), with their corresponding superscripts (dominant or recessive). The superscript must be based on the first letter of the disorder. For example, the mother is a carrier of hemophilia (which is x-linked recessive), so we write XHXh. If the father has hemophilia, we write XhY. Put the pedigree chart using code properly. The situation is given below: Trait: NeurofibromatosisThe dominant form is neurofibromatosis, caused by the production of…
