Two unlinked genes control flower color in snapdragons. You cross a true-breeding yellow flowered plant with a true-breeding white flowered plant. All of the offspring are white flowered. When you intercross these white flowers, the offspring occur in a ratio of 9 white: 3 red: and 4 yellow flowered. What genotypes make up the red flowered offspring? R_W_and rrW_ R_W_only rrW_only R_ww and rrww rrww only

Figure 8.9 In pea plants, round peas (R) are dominant to wrinkled peas (r). You do a test cross between a pea plant with wrinkled peas (genotype rr) and a plant of unknown genotype that has round peas. You end up with three plants, all which have round peas. From this data, can you tell if the parent plant is homozygous dominant or heterozygous?
Figure 8.10 In pea plants, purple flowers (P) are dominant to white (p), and yellow peas (Y) are dominant to green (y). What are the possible genotypes and phenotypes for a cross between PpYY and ppYy pea plants? How many squares would you need to complete a Punnett square analysis of this cross?
More Crosses with Pea Plants: The Principle of Independent Assortment Consider the following cross: P1: AABBCCDDEE aabbccddee F1: AaBbCcDdEe (self-cross to get F2) What is the chance of getting an AaBBccDdee individual in the F2 generation?
More Crosses with Pea Plants: The Principle of Independent Assortment Consider the following cross in pea plants, in which smooth pea shape is dominant to wrinkled, and yellow pea color is dominant to green. A plant with smooth yellow peas is crossed to a plant with wrinkled green peas. The offspring produced peas that were all smooth and yellow. What are the genotypes of the parents? What are the genotypes of the offspring?

In a particular plant, two genes control leaf shape and color. Round leaves (R) are dominant to jagged leaves (r). Yellow fruits (Y) are dominant to white fruits (y). If you crossed a homozygous round, heterozygous yellow plant with a heterozygous round, white plant, what are the genotypes of the plants involved in this cross? Answer RRYY X rryy?

In corn, a triple heterozygote was obtained carrying themutant alleles s (shrunken), w (white aleurone), andy (waxy endosperm), all paired with their normal wildtype alleles. This triple heterozygote was testcrossed, andthe progeny contained 116 shrunken, white; 4 fully wildtype; 2538 shrunken; 601 shrunken, waxy; 626 white;2708 white, waxy; 2 shrunken, white, waxy; and 113 waxy.a. Determine if any of these three loci are linked and,if so, show map distances.b. Show the allele arrangement on the chromosomesof the triple heterozygote used in the testcross.c. Calculate interference, if appropriate.

In corn plants, two pairs of genes control color in the ears of corn. The following genotypes result in various colors: W-C- [red]; wwC- [yellow]; W-cc [white]; wwcc [white]. What is the phenotypic ratio of the dihybrid cross between corn plants heterozygous for both genes? (Dashes mean the allele could be W or w, i.e., WWCC/WwCC/WWCc/WwCc geneotype gives red color)
