Drosohpila Punnet Square of Crosses. I need results of F1 & F2 generation using Punnett Squares for: Make Punnet Squares of the following crosses •Drosophila Female wildtype cross Male White-eye •Drosophila Male wildtype cross Female White-eye •Drosophila Female Wild Type cross Male Scarlet Eye •Drosophila Male Wild Type cross Female Scarlet Eye Also, Which allele is heterozygous and which is homozygous, & which is dominant and which is recessive?
Red-flowering snapdragons are homozygous for allele RI. White-flowing snapdragons are homozygous for a different allele (R2). Heterozygous plants (R1 R2) bear pink flowers. What phenotypes should appear among first-generation offspring of the crosses listed? What are the expected proportions for each phenotype? a. R1R1 R1R2 b. R1R1 R2R2 c. R1R2 R1R2 d. R1R2 R2R2
Use Punnett squares in solving the following problems. 1. In garden peas, a plant that is homozygous for round seeds is crossed with a plant that is heterozygous. Interpret the result of the cross. What percentage of plants will have round seeds? What is the chance of the offspring being heterozygous? Give the phenotypic and genotypic ratios. Give the phenotypes and genotypes. Explain the results of the offspring.
Background Problem N° 5 Objective: To apply classical transmission genetics in a trihybrid cross. Flower position, stem length, and seed shape were three of the traits that Mendel studied. Each is controlled by an independently assorting BOTANIQUE. Légumineuses gene and has dominant and recessive expression: Solve it using the rules of probability instead Axial (flowers originate along the stems) is dominant over terminal (flowers on top of the stem). of Punnet squares, bifurcation forks, or mental visualization. Long ("tall") stem is dominant over short stem ("dwarf"). Let's use the symbols T, t for genes determining axial vs. terminal; Le, le for tall vs. dwarf; K, k for round vs. wrinkled (from Round seed is dominant over wrinkled. If a plant that is heterozygous for all three characters were allowed to self-fertilize, what proportion of the offspring would be expected to be as follows? the German noun knitter = wrinkle). One final note: the phenotype "tall plant" may be conferred…
Problem: A series of experiments shows that oil content in a diploid grain is influenced by five genes (a through e) with additive alleles.

000O Q31 A Mendelian experiment consisted of breeding tall pea plants bearing violet flowers with short pea plants bearing white flowers. The progeny all bore violet flowers, but almost half of them were short. This suggests that the genetic makeup of the tall parent can be depicted as: TTWW TtWw
Dihybrid Cross Problem 2: When does a phenotype ratio of 9:3:3:1 occur? A phenotype ratio of 9:3:3:1 in the offspring of a mating of two organisms heterozygous for two traits is expected when: A. the genes reside on the same chromosome B. each gene contains two mutations C. the gene pairs assort independently during meiosis D. only recessive traits are scored E. none of the above
Background Problem N° 7 Objective: To illustrate the use of test crosses to establish unknown genotypes. In dogs (Canis familiaris), there is a hereditary deafness caused by the recessive gene d. A kennel owner has a male dog (Fido, of course) that she wants to use for breeding purposes. She comes to you for genetlc advice. The dog can hear, so you know that his genotype is either DD or Dd. For this problem, you are allowed to use Punnett squares or pedigrees. If Fido's genotype were Dd, the owner would not use him for breeding so that the deafness gene will not be passed on. The dog's genotype can be ascertained via a test-cross with a deaf female (dd). Draw Punnett squares or pedigrees to illustrate these two possible crosses. A test cross uses an individual whose genotype we can be certain of, i.e., a homozygous recessive for a particular trait. Such organism is crossed with one whose genotype we do not know (remember the homozygous recessive always express the recessive phenotype).…
Dihybrid Cross Problem 10: Exceptions to the 9:3:3:1 ratio of offspring? If Mendel's crosses between tall, spherical-seeded plants and short, dented- seeded plants had produced many more than 1/16 short, dented-seeded plants in the F2 generation, he might have concluded that: A. the dented seed and short traits are unlinked. B. he would not have concluded any of the above. C. all traits in peas assort independently of each other. D. the spherical seed and tall traits are linked. E. all traits in peas are linked.
Topic: Modifications of Mendelian Genetics LEARNING ACTIVITY and ASSESSMENT 1. In addition to the ABO blood group, many others have been identified in humans.

What will be the probability of the genotypes and phenotypes that would be produced in crosses involving the following phenotypes: а. Туре М and type N b. Туре М and type MN c. Type N and type N d. Type MN and type MN 2. Could a child of type N result from the mating of M and MN? Justify your answer.
