Consider a cross to investigate the pea pod texture trait, involving constricted or inflated pods. mendel found that the traits behave according to a dominant/ recessive pattern in which inflated pods were dominant. if you performed this cross and obtained 650 inflated-pod plants in the f2 generation, approximately how many constricted-pod plants would you expect to have?

a. 600
b.165
c. 217
d. 468

C. 217

Explanation:

Mendel obtained the phenotypic ratio of 3 dominant: 1 recessive in the F2 generation of a monohybrid cross. According to the given information, inflated pods are dominant over the constricted one.

Let's assume that the allele C is responsible for inflated pods while the recessive allele "c" gives constricted pods. A cross between two pure breeding plants with inflated (CC) and constricted pods (cc) would give all the plants with inflated pods (Cc) in the F1 generation. A cross between two F1 plants would obtain F2 generation in following ratio=3 Inflated: 1 constricted.

Therefore, if 650 plants with inflated pods were obtained in the F2 generation, 217 plants must have constricted pods since 650:217 is almost equal to 3:1.

explanation:

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."
