A true-breeding pea plant with round and green seeds was crossedto a true-breeding plant with wrinkled and yellow seeds. Roundand yellow seeds are the dominant traits. The F1 plants wereallowed to self-fertilize. What are the following probabilities forthe F2 generation?A. An F2 plant with wrinkled, yellow seeds.B. Three out of three F2 plants with round, yellow seeds.C. Five F2 plants in the following order: two have round, yellowseeds; one has round, green seeds; and two have wrinkled,green seeds.D. An F2 plant will not have round, yellow seeds

In corn plants, a dominant allele (I) inhibits kernel colour, but the recessive allele (i) permits colour when homozygous. At a different locus, the dominant gene P causes purple kernel colour, and the homozygous recessive genotype pp causes red kernels. If plants that are heterozygous at both loci are crossed, what will be the phenotypic ratio of the F1 generation?

States) B *In nature, individual plants of Plectritis congesta bear either winged or wingless fruits. Three individual plants were collected from nature (thus not necessarily pure breeding) before flow- ering and were either crossed or self-pollinated. The results are shown below. Number of progeny plants Wingless 0 30 80 0 31 Cross 1 2 3 4 TU Parental phenotypes Winged #1 (selfed) Winged #/2 (selfed) Wingless #1 (selfed) Winged #1 X Wingless #1 Winged #2 X Wingless #1 Winged #1 X Winged #2 The fruits of two different forms of Plectritis congesta, the sea blush: Wingless fruit and winged fruit. a) Give a concise genetic hypothesis for the inheritance of fruit shape as determined from these crosses (include the number of genes, number of alleles, and dominance relation- ship between alleles).² b) Give the most probable genotypes of: (define your alleles) 2 Winged #1 Winged #2 Wingless #1 1) 2) c) If you self-pollinate the winged #2 plant and planted six seed, what is the probability of…

In the tomato, three genes are linked on the same chromosome. Tallis dominant to dwarf, skin that is smooth is dominant to skin that ispeachy, and fruit with a normal rounded tomato shape is dominantto oblate (flattened) shape. A plant that is true-breeding for thedominant traits was crossed to a dwarf plant with peachy skin andoblate fruit. The F1 plants were then testcrossed to dwarf plants withpeachy skin and oblate fruit. The following results were obtained: 151 tall, smooth, normal33 tall, smooth, oblate11 tall, peach, oblate2 tall, peach, normal155 dwarf, peach, oblate29 dwarf, peach, normal12 dwarf, smooth, normal0 dwarf, smooth, oblate A) Determine the coefficient of coincidence and the interference for these three loci.
