His results were 126 red flowering plants and 122 white flowered plants a. which Punnett Square applies? He crossed a red flowered plant with a white flowered plant. His results were 307 red flowering plants and O white flowered plants. Which Punnett Square applies? b. He crossed a red flowered plant with a red flowered plant. His results were 306 red flowering plants and 110 white flowered plants. Which Punnett Square applies? c. He crossed a red flowered plant with a red flowered plant. His results were 300 red flowering plants and O white flowered plants. Which Punnett Square applies? d. Suppose in a strain of soybeans, high oil (H) content in the seeds is dominant to low oil content and four seeds (E) in a pod is dominant to two seeds in a pod. A farmer crosses two soybean plants, both with high oil content and four seeds per pod. The resulting F1 offspring have a phenotypic ratio of 9:3:3:1 (High oil / four seeds: High oil/ two seeds: Low oil/ four seeds : Low oil / two seeds). No need to draw a punnet square here, but you DO need to SHOW YOUR THOUGHT PROCESS through your work 8. What genotype were the parent plants? Suppose the farmer chooses two of the high oil/ four seed plants and crosses them. The F2 generation has all high oil/ four seed phenotypes. What were the possible genotypes of the plants chosen by the farmer to cross? Which known genotypes might the farmer cross her high oil/ four seed plants with to determine their genotype? a. b. c.Explanation / Answer
7. A. 4 - Rr and rr are equal ratio 1:1 126 Red : 122 White
B. 1 All have dominat R in the offspring. All looks red color and no white
C. 3. This is 3 : 1 ratio
4. 2 The parents are RR and Rr both are dominant. The offspring also got all dominant R.
8. HH - high oil content hh - low oil content / EE - 4 seeds ee - 2 seeds
A. The genotype is heterozygous HhEe X HhEe
B. HHEE X HhEE , HHEE X HhEe
C. We have to do the test cross.
HHEE X hhee - It give all are High oil 4 seed. we concluded the alleles all are dominant.
HhEe X hhee - It gives 4 phenotypes . we concluded the parents all in heterozygote.
