The following pedigree shows the pattern of inheritance of red-green color blindness in a family. Females are shown as circles and males as squares; the squares or circles of individuals affected by the trait are filled in black. What is the chance that a son of the third-generation female indicated by the arrow will be color blind if the father is not color blind? If he is color blind?
A pedigree analysis was performed on the family of a man with schizophrenia. Based on the known concordance statistics, would his MZ twin be at high risk for the disease? Would the twins risk decrease if he were raised in an environment different from that of his schizophrenic brother?
Gregor Mendel discovered the basis of heredity with his sweet pea plant experiments. In his studies, he determined that certain traits, such as pod color and pea shape, express complete dominance. A cross occurs between a plant with heterozygous yellow pods and wrinkled peas and a plant with green pods and heterozygous round peas. What is the probability that the offspring will exhibit recessive genes for both traits? A - 1/2B - 1/4C - 1/8D - 1/16
If body-color B is dominant to green body color b what would the genotype be for a heterozygous individual be? Using the blue B and a green b body color from above create a Punit square that represents the offspring of two heterozygous parents? what is the probability that they will have a child with a green body-color If the child is green what is its genotype? Cross a green parent with a homozygous blue parent. What color will their kids be?
In a certain animal, black coat (B) are dominant to white coat (b). In a genetic cross of two animals that are heterozygous for coat color, what is the probability of having white coat? Write in fraction form
Among dogs, short hair is dominant to long hair and dark coat color is dominant to white (albino) coat color. Assume that these two coat traits are caused by independently segregating gene pairs. For each of the crosses given below, write the most probable genotype (or genotypes if more than one answer is possible) for the parents. It is important that you select a realistic symbol set and define each symbol below. Assume that for cross (d), you were interested in determining whether fur color follows a 3:1 ratio. Set up (but do not complete the calculations) a Chi-square test for these data [fur color in cross (d)].
Mendel crossed two Pea plants for plant height and flower color Tall plant (T) is dominant to Short Plant (t). Purple Flower (P) is dominant to white flower (p). Using the following information perform the dihybrid cross using punnett squares that will predict all possible genotypes of the offspring and list the number and description of the phenotypes of the offspring. A. One plant homozygous dominant for plant height and flower color crossed with another plant homozygous recessive for plant height and heterozygous for flower color.
In corn plants, a dominant allele Z inhibits kernel color, while the recessive allele z permits color when homozygous. At a different locus, the dominant allele X causes purple kernel color, while the homozygous recessive genotype causes red kernel color. If corn plants heterozygous for both the Z and X genes are crossed, what are the chances that the offspring will have purple kernels? Enter your answer as a decimal fraction in the box (e.g. 0.25).
a. A variety of fruit bearing plants with the dominant allele A produces cream-coloured fruit while aa plants produce pink or red fruit. Red fruit is produced if allele B is present, and pink fruit is produced when the genotype is bb. What are the expected F2 phenotypes and proportions from intercrossing the F1 offspring of a cross between two plants with the genotype AAbb and aaBB? b. A certain animal can have brown, red, black or gray fur. Assume that fur colour is controlled by a single gene with multiple alleles in a dominance series where black (B1) > brown (B2) > red (B3) > gray (B4). Give the genotypes of two phenotypically different heterozygotes that when crossed produce offspring with the phenotypic ratio of 1 red : 2 black : 1 brown.
a)1 The allele for tall pea plants is dominant over the allele for short pea plants. If two heterozygous plants are crossed, what will the genotypic and phenotypic ratios be? b)2 Purple flowers are dominant over white flowers, and green pods are dominant over yellow pods in pea plants. What would the probability be of producing a pea plant with white flowers and yellow pods from parent plants that are heterozygous for each trait? c)3 Red eyes are dominant on fruit flies but an x-linked recessive allele will produce white-eyed flies. If a pure breeding red-eyed female mates with a white-eyed male, what is the probability of white eyes in the F1 generation?
In cultivated flowers called “stocks,” the recessive genotype of one locus (aa) prevents the development of pigment in the flower thus producing a white color. In the presence of the dominant allele A, alleles at another locus may be expressed as follows: B_ = red. bb = cream. a) When cream stocks of the genotype Aabb are crossed to red stocks of the genotype AaBb, what genotypic and phenotypic proportions are expected in the progeny? b) When dihybrid red stocks are crossed together, what phenotypic ratio is expected among the progeny? c) If red stocks crossed to white stocks produced progeny with red, cream and white flowers, what are the genotypes of the parents? Show the results of the cross based on your answer.
In snapdragons, red flower color (R) is incompletely dominant over white flower color (r), so that the heterozygote has pink flowers. A red snapdragon is crossed with a white snapdragon, and the F1 are intercrossed to produce F2. What is the genotype and phenotypes of the F1 and F2, along with their expected proportions? If the F1 are backcrossed to the white parent, what will be the expected genotype and phenotype of the offspring? If the F1 are backcrossed to the red parent and the resulting progeny are intercrossed, what is the expected proportions of genotypes and phenotypes in the progeny?
