- Perform two consecutive crosses similar to those of Mendel for the following individual plants. Plants with round seeds (RR) are crossing with plants with wrinkled seeds (rr). After the first cross, cross the offspring together to generate F2 offspring. What are the genotypic and phenotypic ration of F2?Mendelian ratios are modified in crosses involving autotetraploids.Assume that one plant expresses the dominant trait greenseeds and is homozygous (WWWW). This plant is crossed to onewith white seeds that is also homozygous (wwww). If only onedominant allele is sufficient to produce green seeds, predict theF1 and F2 results of such a cross. Assume that synapsis betweenchromosome pairs is random during meiosis.Assume that smooth seed coats are dominant over rough seed coat. If two pea plants that are both Heterozygous for seed coats are crossed, what do you expect in the offspring (the f1 generation)? Specifically, what genotypes, what phenotypes, and in what ratios? (Use S for the smooth seed coat and s for the rough seed coat.) (Again, it is helpful to write out all the possible genotypes and give the phenotype for each genotype before answering the specific question.) Be careful in writing capital S and lower case.
- Gregor Mendel examined the inheritance of two traits in pea plants: seed coat texture and colour. Seed coat texture can be represented as S-smooth and s-wrinkled, and seed coat colour can be represented as Y-yellow and y-green. SSYY plants were crossed with ssyy plants to yield F1 pea seeds that were all smooth and all yellow. By crossing plants grown from these F1 seeds, Mendel obtained four different phenotypes of F2 seeds: • smooth and green seeds wrinkled and green seeds smooth and yellow seeds wrinkled and yellow seeds ● Use the following information to answer the next question. ● The F2 phenotypic ratio that Mendel obtained upon crossing two heterozygous smooth and yellow F1 individuals would have been: smooth and green wrinkled and green : smooth and yellow: wrinkled and yellow Record only the numeric values associated with the phenotypes. (Do not include the colons, spaces, commas, etc.)The allele G for yellow stigma is completely dominant to green (g). Supposing two strains of autotetraploid plants are available and their genotypes are as follows: GGgg – in this plant the gene is close to the centromere Gggg – in this plant the gene is far from the centromere If these two plants are crossed: a) provide the gametes that can be obtained from the two plants; b) provide the genotypic and phenotypic ratios of the offspring.Assume that the trihybrid cross AABBrr x aabbRR is made in a plant species. Assume that A and B are dominant alleles, but there is no dominance effect of alleles at the R locus. a) How many different gametes are possible in the F1generation? What are the genotypes of these gametes? b) What is the probability of the parental aabbRR genotype in the F2 progeny? c) What proportion of the F2 progeny would be expected to be homozygous for all three genes?
- What is the genotype of the F1 generation of the corn dihybrid cross described above? What is the phenotype of the F1 generation of the corn dihybrid cross described above? What are the possible maternal and paternal genotypes of the F1 gametes of the corn dihybrid cross described above?In the snail Limnaea peregra, coiling of the shell is determined by the genes D for right-hand coiled shells, and d for left-hand coiled shells. The gene for the right-hand coiled shell is dominant. The direction of coiling is determined by the genotype of the maternal parent producing the egg, regardless of the progeny's genotype. Which of the following crosses could give a left-hand coiled shell heterozygote? A. right-hand coiled dd female X left-hand coiled DD male B. left-hand coiled DD female X right-hand coiled dd male C. left-hand coiled DD female X left-hand coiled DD male D. right-hand coiled dd female X left-hand coiled dd maleIn snapdragons, red flower color (R) is incompletely dominant over white flower color (r). The hybrids or heterozygous plants (Rr) are pink in color. a) Show the genotype for a white flower and for a red flower. b) If a red-flowered plant is crossed with a white-flowered plant, what are the genotypes and phenotypes of the F1 generation plants? c) What genotypes and phenotypes will be produced in the F2 generation? d) How did the genotypic and phenotypic ratio compare to each other in this incomplete dominance cross? e) What would the phenotypic ratio have been if this had been complete dominance? f) What kind of offspring can be produced if a red-flowered plant is crossed with a pink-flowered plant? g) What kind of offspring is/are produced if a pink-flowered plant is crossed with a white-flowered plant?
- In goats, development of the beard is due to a recessive gene. The following cross involving true-breeding goats was made and car- ried to the F2 generation: P;: bearded female x beardless male F1: all bearded males and beardless females ´1/8 beardless males | 3/8 bearded males 3/8 beardless females 1/8 bearded females F; × F, Offer an explanation for the inheritance and expression of this trait, diagramming the cross. Propose one or more crosses to test your hypothesis.In guinea pigs, rough coat (R) is dominant to smooth coat (r). If a homozygous rough-coated animal is crossed with a smooth-coated one: What will be the phenotype(s) of the F1 generation? What will be the phenotype(s) of the F2 generation? What will be the phenotype(s) of the offspring resulting from a cross of an F1 individual back to its rough parent? What will be the phenotype(s) of the offspring of a cross of an F1 individual back to its smooth parent?In pea plants, yellow seeds (Y) are dominant to green seeds (y) and round seeds (R) are dominant to wrinkled seeds (). The genes for seed color and seed shape are on different chromosomes. Two true-breeding parents, one with yellow round peas and the other with green wrinkled peas, are crossed to produce a hybrid (heterozygous) F₁. Two F₁ individuals are crossed to give an F2; this is depicted in the Punnett square below. Place the correct genotypes in the Punnett square and the place the correct phenotypic ratios next to their appropriate phenotype on the right.
