- More Crosses with Pea Plants: The Principle of Independent Assortment Think about this one carefully. Albinism and hair color are governed by different genes. A recessively inherited form of albinism causes affected individuals to lack pigment in their skin, hair, and eyes. In hair color, red hair is inherited as a recessive trait and brown hair is inherited as a dominant trait relative to red hair. An albino woman whose parents both have red hair has two children with a man who is normally pigmented and has brown hair. The brown-haired partner has one parent who has red hair. The first child is normally pigmented and has brown hair. The second child is albino. a. What is the hair color (phenotype) of the albino parent? b. What is the genotype of the albino parent for hair color? c. What is the genotype of the brown-haired parent with respect to hair color? Skin pigmentation? d. What is the genotype of the first child with respect to hair color and skin pigmentation? e. What are the possible genotypes of the second child for hair color? What is the phenotype of the second child for hair color? Can you explain this?Traits are are controlled by a single gene, such as corn color, can be used fo predictability of trait in inheritance in humans also. This is especially import for parents who may carry alleles that code for diseases. Parents can predic probabilities that their child might inherit a disease if they know their own genotype. Parents that are carriers (heterozygous) may not show disease, bu can still pass on a disease allele. Read the scenario below (in bold). Using a separate piece of paper and draw out a Punnett square, with required information (questions 1-5). The letter D will be used to represent the domina (healthy) allele. Tom and his wife Julie are both carriers for cystic fibrosis, an autosomal recessive disease. Draw a Punnett square and be sure to include the following information for full credit: 1. Place the parents alleles at the top and on the left side. 2. Write in the allele crosses inside the Punnett squares. 3. Write out the genotypes probabilities for an offspring. 4.…A researcher studied 6 independently assorting genes in a plant. Each gene has a dominant and a recessive allele: R black stem, r red stem; D tall plant, d dwarf plant; C full pods, c constricted pods; O round fruit, o oval fruit; H hairless leaves, h hairy leaves; W purple flower, w white flower. From the cross Rr Dd Cc Oo Hh Ww (male) x Rr dd Cc oo Hh ww (female): How many different kinds of gametes can be formed from both parents? What is the frequency of obtaining a sperm cell with at 3 dominant and 3 recessive alleles? How many phenotypes are possible among the progeny? How many genotypes? What is probability of obtaining a black, dwarf, constricted, oval, hairy, purple phenotype in the progeny? What is probability of obtaining progeny with exactly same genotype as the female parent? As the male parent? If both parents were heterozygous for all genes, what is the probability of obtaining progeny with at least 2 recessive traits? From the cross in (f), will there be…
- Several alleles affect traits of roses, such as plant form and bud shape. Alleles of one gene govern whether a plant will be a climber (dominant) or shrubby (recessive). All F1 offspring from a cross between a true-breeding climber and a shrubby plant are climbers. If an F1 plant is crossed with a shrubby plant, about 50 percent of the offspring will be shrubby; 50 percent will be climbers. Using symbols A and a for the dominant and recessive alleles, make a Punnett- square diagram of the expected genotypes and phenotypes the cross between the F1 offspring and the shrubby plant.Clubfoot is a common congenital birth defect. This defect is caused by a number of genes but appears to be phenotypically distributed in a noncontinuous fashion. Geneticists use the threshold model to explain the occurrence of this defect. Explain this model. Explain predisposition to the defect in an individual who has a genotypic liability above the threshold versus an individual who has a liability below the threshold.Figure 19.2 In plants, violet flower color (V) is dominant over white (v). If p = .8 and q = 0.2 in a population of 500 plants, how many individuals would you expect to be homozygous dominant (VV), heterozygous (Vv), and homozygous recessive (vv)? How many plants would you expect to have violet flowers, and how many would have white flowers?
- Figure 8.9 In pea plants, round peas (R) are dominant to wrinkled peas (r). You do a test cross between a pea plant with wrinkled peas (genotype rr) and a plant of unknown genotype that has round peas. You end up with three plants, all which have round peas. From this data, can you tell if the parent plant is homozygous dominant or heterozygous?More Crosses with Pea Plants: The Principle of Independent Assortment Determine the possible genotypes of the following parents by analyzing the phenotypes of their children. In this case, we will assume that brown eyes (B) is dominant to blue (b) and that right-handedness (R) is dominant to left-handedness (r). a. Parents: brown eyes, right-handed brown eyes, right-handed Offspring: 3/4 brown eyes, right-handed 1/4 blue eyes, right-handed b.

- n pea plants, the appearance of flowers along the main stem is a dominant phenotype called axial and is controlled by the T allele. The recessive phenotype, produced by the E t allele, has flowers only at the end of the stem and is called terminal. Seedpod form iS determined by a second gene. The dominant phenotype inflated is controlled by allele C, and a recessive constricted form, produced by allele c. A pure breeding axial, constricted plant is crossed to one that is pure-breeding terminal, inflated. A. The F1 progeny of this cross are allowed to self-fertilize. What is the expected distribution of phenotypic classes among the F2 progeny? -> TTcc t난 CC x Et 1:2:1To understand this research, you must be familiar with some basic genetic terminology.
