They came in several varieties.
They were capable of self-fertilization.
They were easy to cross.
Their anthers could be removed prior to pollination.
All of the above were advantages.

Expert Solution & Answer

Summary Introduction

Introduction:

Gregor Mendel has chosen pea plants for experiments because they are easily grown, have many offspring per mating, could fertilize themselves and have easily observable varieties of genotype and phenotype.

Answer to Problem 1TY

The correct answer is option (e) all of the above.

Explanation of Solution

Explanation/justification for the correct answer:

Option (e) all of the above. Peas are found in many varieties that vary in features such as seed size, seeds, flowers, and stems. A female gamete of the same plant is fertilized by a male gamete; this is called self-fertilization. The female and male sex organs are present in the single flower (same flower) of peas. Garden peas are ease of making crosses. The process is known as hybridization when two individuals of the same species are crossed or bred to each other with different characteristics and the offspring are refers to as hybrids. The anther can be removed so that the flower could not self-fertilize and the pollen can be transfer to another flower of a different plant. So, the correct answer is option (e).

Explanation for incorrect answer:

Option (a) They came in several varieties. Peas are present in several varieties that differ in features such as the appearance of seeds, flowers, pods, and stems. Thus, this is not only the correct option. So, this is an incorrect option.

Option (b) They were capable of self-fertilization. In a pea plant, a female gamete is fertilized by a male gamete which is said as self-fertilization. Thus, this is not only the correct option. So, this is an incorrect answer.

Option (c) They were easy to cross. When two pea plants with different features are crossed or bred to each other, the process is said to as hybridization and the offsprings are referred to as hybrids. Thus, this is not only the correct option. So, this is an incorrect answer.

Option (d) Their anthers could be removed before pollination. The anther can be removed so that the flower could not self-fertilize and the pollen can be transfer to another flower of a different plant. Thus, this is not only the correct option. So, this is an incorrect answer.

Conclusion

Experimental advantages of using pea plants included (d) all of the above were advantages.

Students have asked these similar questions

A sample of blood was taken from the above individual and prepared for haemoglobin analysis. However, when water was added the cells did not lyse and looked normal in size and shape. The technician suspected that they had may have made an error in the protocol – what is the most likely explanation? The cell membranes are more resistant than normal. An isotonic solution had been added instead of water. A solution of 0.1 M NaCl had been added instead of water. Not enough water had been added to the red blood cell pellet. The man had sickle-cell anaemia.

With reference to their absorption spectra of the oxy haemoglobin intact line) and deoxyhemoglobin (broken line) shown in Figure 2 below, how would you best explain the reason why there are differences in the major peaks of the spectra? Figure 2. SPECTRA OF OXYGENATED AND DEOXYGENATED HAEMOGLOBIN OBTAINED WITH THE RECORDING SPECTROPHOTOMETER 1.4 Abs < 0.8 06 0.4 400 420 440 460 480 500 520 540 560 580 600 nm 1. The difference in the spectra is due to a pH change in the deoxy-haemoglobin due to uptake of CO2- 2. There is more oxygen-carrying plasma in the oxy-haemoglobin sample. 3. The change in Mr due to oxygen binding causes the oxy haemoglobin to have a higher absorbance peak. 4. Oxy-haemoglobin is contaminated by carbaminohemoglobin, and therefore has a higher absorbance peak 5. Oxy-haemoglobin absorbs more light of blue wavelengths and less of red wavelengths than deoxy-haemoglobin
