Imagine you are performing a cross involving seed color in garden pea plants. What Fi offspring would you expect if you cross true-breeding parents with green seeds and yellow seeds? Yellow seed color is dominant over green. 100 percent yellow-green seeds 100 percent yellow seeds 50 percent yellow, 50 percent green seeds 25 percent green, 75 percent yellow seeds
In cats, the genotype AA produces tabby fur color; Aa is also a tabby, and aa is black. Another gene at a different locus is epistatic to the gene for fur color. When present in its dominant W form (WW or Ww), this gene blocks the formation of fur color and all the offspring are white; ww individuals develop normal fur color. What fur colors, and in what proportions, would you expect from the cross AaWw Aa Ww?
A testcross is a way to determine ________. a. phenotype b. genotype c. dominance
The dominant C allele of a gene that controls color in corn produces kernels with color; plants homozygous for a recessive c allele of this gene have colorless or white kernels. What kinds of gametes, and in what proportions, would be produced by the plants in the following crosses? What seed color, and in what proportions, would be expected in the offspring of the crosses? a. CCCc b. Cccc c. CcCc
1. In humans, hemophilia is a sex linked trait. Females can be normal, carriers, or have the disease. Males will have the disease or not (but they won't be ever carriers) XH XH = female, normal XH Xh = female, carrier Xh Xh = female, hemophilic XH Y = male, normal Xh Y = male, hemophilic a) Show the cross of a man who has hemophilia with a woman who is a carrier. b) What is the probability that their children have the disease
2. Cross a Brown and White Spotted Cow with a White Cow. What is the percentage of the genotype and phenotype of the offspring? What type of punnett square will you be using for this cross? Codomnent BB WW Parents: Genotypes: P1 x P2 Offspring: Genotype: Phenotype:
1. Do a punnett square for the cross shown below between a male and female, both with Hemophilia, an X- linked recessive disease. Females are represented by a circle and males by a square. Darkened shapes mean the individual has the disease.
3. In humans, hemophilia is a sex linked trait. Females can be normal, carriers, or have the disease. Males will either have the disease or not (but they won't ever be carriers). Show the cross of a man who has hemophilia with a woman who is a carrier. XH XH = female, normal XH Xh= female, carrier xh Xh= female, hemophiliac XH Y = male, normal Xh Y= male, hemophiliac 4. What is the probability that their children will have the disease? 5. A woman who is a carrier "marries" a normal man. Show the cross. What is the probability that their children will have hemophilia? What sex will a child in the family with hemophilia be? 6. In a certain cactus, prickly spines can be two pronged or one pronged. If a true breeding one- pronged cactus is crossed with a true breeding two-pronged cactus, the F1 generation has a mixture of spines, some are two-pronged, some are one-pronged. a. Is this an example of codominance or incomplete dominance? b. Show the F2 generation (a cross between the two…
6. Haemophilia is a relatively uncommon, sex-linked condition that is determined by a recessive allele on the X chromosome. It is a condition in humans in which the blood fails to clot normally. The following diagram shows a pedigree for haemophilia. Joe Sally Tom Tina 1 Jim Sheila 2 3 ? Mary Barry 4 5 6 7 Affected male Unaffected male Affected female Unaffected female a) Determine the possible genotypes for Jim, Sheila and their children (Sally, Tom and Mary). Use the symbols XH for the normal allele and Xh for the mutant allele and Y for the Y chromosome. Briefly state your logic in each case. b) Tom and Tina are expecting their first child and want to know the probability that the child had haemophilia i) if it is a boy or ii) if it is a girl. How would you advise them?
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.
9. In fruit flies, eye color is carried on the X chromosome. The allele for red eyes is dominant over its recessive allele, white eyes. Cross a homozygous, red-eyed female to white-eyed male. white cefes red eyes What is the genotype of the male? What is the genotype of the female? X xxx xx Y XY XY Genotypes x' x X Y How many genotypes are possible among the offspring? How many phenotypes are possible among the offspring? What is the probability of getting offspring that are red-eyed males? What is the probability of getting offspring that are white-eyed males? What is the probability of getting offspring that are red-eyed females? What is the probability of getting offspring that are white-eyed females? Phenotypes red eyes white eyes
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?
