Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Concept:
Gregor Johann Mendel performed systematic hybridization experiments between 1856 and 1863, establishing the basic principles of heredity.
His scientific success was largely due to his careful selection of the garden pea (Pisum sativum) as an experimental model organism.
This question tests the biological attributes that made the garden pea plant advantageous for genetic research.
Step 1: Analyzing Biological Characteristics of Pea Plants:
1. Cultivation (Statement A): Garden pea plants are annual herbs that are easy to cultivate and maintain in small experimental plots. Thus, (A) is correct.
2. Short Life Cycle (Statement C): Pea plants complete their life cycle within a single growing season (few months), enabling researchers to study multiple successive generations in a short time. Thus, (C) is correct.
3. Ease of Hybridization (Statement D): Pea flowers are naturally self-pollinated (cleistogamous), but they can easily be cross-pollinated artificially by removing anthers (emasculation) and dusting pollen from another plant. Thus, (D) is correct.
Step 2: Evaluating Non-Relevant Factors:
Pest Resistance (Statement B): Pea plants are not uniquely or inherently pest-resistant, and pest resistance was neither an attribute considered by Mendel nor a valid advantage cited in classical genetic literature.
Step 3: Final Answer:
The valid advantages are (A), (C), and (D).
Thus, Option (D) is the correct answer.

Like Paleolithic, Neolithic is also a Greek word. It means 'New Stone'. The period since the discovery of agriculture to the rise of urban civilization has been bracketed, as New Stone or Neolithic Age. This Age lasted approximately from 8000BC to 3000BC. The earlier anthropologists conceived everything on the basis of technological types, so they distinguished two grand divisions in Stone Age, which were different from each other by the technique of stone working. Palaeolithic tools and implements were made solely by chipping. They were very crude in nature. But the Neolithic stone objects were pecked, ground, rubbed and polished; they were far better in finishing as well as in effectiveness. Man was no longer a food-gatherer, he became a food-producer at the advent of Neolithic.
Twentieth Century anthropologists defined Neolithic Age in terms of domesticated plants and animals. They also counted the presence of pottery and absence of metal as indispensable criteria for a pure Neolithic site. V. Gordon Childe mentioned that the Neolithic had opened an entire new way of life and he termed it as 'Neolithic Revolution'. After the end of Pleistocene Ice Age, first acquisition of domestic plants and animals stood as the greatest achievement of man and therefore the period has been recognized as a great turning point or 'revolution', perhaps comparable in importance only with the 'Industrial Revolution' of recent period. But the origin and early spread of agriculture is still a matter of conjecture and only fragmentary evidences are found on this topic. There is no area in the world where the stages from pure hunting and gathering to farming can be traced step by step in adequate detail. However, the early development of agriculture was rooted in the environmental and cultural conditions at the end of Pleistocene epoch. By this time, the biological development of man was complete as evident in the skeletal remains of modern type of man corresponding to the particular period. It is therefore assumed that the people of this period had grown the capacities for cultural innovation. Discovery of agriculture belongs to: - Read the passage given below and answer the question.
Mendel’s experiment with tall and dwarf peas, therefore, showed both homozygous and heterozygous zygotes. In pure tall variety, two factors (alleles) remain identical forming TT combination. Similarly, the pure dwarf variety shows tt combination. The hybrid tall plants of the first filial generation (F1) carry two unlike factors, Tt. Mendel in his experiment clearly established the fact that the recessive characters are not expressed in heterozygous condition, but will be expressed in recessive homozygotes (dwarf pea). Ina cross between true-breed contrasting varieties, we can classify F2 progeny (grandchildren grogeny) in two ways, either according to their appearance (phenotype) or according to their genetic composition (genotype). The phenotype classifies thiee individuals as tall out of four, whereas genotype identifies two hybrids (Tt) among the talls. Genotypically the F2 generation is composed of 1 TT, 2 Tt and 1 tt. The terms phenotype and genotype therefore refer to the visible expression of the genes (or Mendelian factors) and the actual genetic constitution of an individual respectively. Mendel discovered the important fact, that in the F1 hybrids, the parental characteristics (or factors or alleles) were not lost or mixed to produce the intermediates, rather the factors or alleles remain segregated. This non-mixing of alleles in the hybrid and their subsequent segregation (equal proportion is maintained in the gamete) is principle of Segregation of Mendel's first law. - The science of genetics in an important discipline which deals with the:
- Scientists associated with rediscovery of Mendel's law were.
- The production of gametes by the parents, the formation of the Zygotes, the F1 and F2 plants can be understood from a diagram called as:
