Introduction: Gregor Johann Mendel who is known as the “Father of modern genetics” was the first person to conduct experiments on seven characters of pea plant. Based on these experiments, he framed three laws of inheritance, namely “Law of dominance, “Law of segregation”, and “Law of independent assortment.”

Answer to Problem 1IQ

Pictorial representation: Fig.1 represents a cross between round-seeded and wrinkled-seeded pea plants.

Study Guide for Campbell Biology, Chapter 14, Problem 1IQ

Fig.1: A cross between round seeded and wrinkled-seeded pea plants

Explanation of Solution

The description of cross between the round-seeded and wrinkled-seeded pea plants from parental generation till F2 generation is given below:

The parental generation includes the phenotypes that are round seeds and wrinkled seeds and their genetic makeup includes RR and rr, respectively.
The gametes of the round and wrinkled seeds are R and r, respectively.
These gametes fertilize to produce only round seeds in the F₁ generation. This is because their genetic makeup is Rr and the allele for round seeds R is dominant over the wrinkled seeds r.
The F₁ round-seeded plants whose genotype is Rr segregate into R and r at the time of gamete formation and fuse together to give rise to F₂ generation.
The F₂ generation gives rise to plants with different genotypes that are RR, Rr, and rr giving rise to both round and wrinkled seeds.
The plants with round and wrinkled seeds are produced in the ratio 3 rounded:1 wrinkled seed plants, whereas their genetic makeup are found in the ratio 1RR: 2Rr: 1rr.

Conclusion

The ratios of a cross between round versus wrinkled seeds are as follows:

Phenotypic ratio of round versus wrinkled seeds is 3:1

Genotypic ratio of RR: Rr: rr is 1:2:1.

Preoperative Diagnosis: Torn medial meniscus, left knee Postoperative Diagnosis: Combination horizontal cleavage tear/flap tear, posterior horn, medial meniscus, left knee. Operation: Arthroscopic subtotal medial meniscectomy, left knee Anesthetic: General endotracheal Description of Procedure: The patient was placed on the operating table in the supine position and general endotracheal anesthesia was administered. After an adequate level of anesthesia was achieved, the patient's left lower extremity was prepped with Betadine scrubbing solution, then draped in a sterile manner. Several sites were then infiltrated with 1% Xylocaine solution with Epinephrine to help control bleeding from stab wounds to be made at these sites. These stab wounds were made anterolaterally at the level of the superior pole of the patella for insertion of an irrigation catheter into the suprapatellar pouch area, anterolaterally at the level of the joint line for insertion of the scope and anteromedially at…
