In Garden Pea, yellow colour of cotyledons is dominant over green and round shape of seed is dominant over wrinkled. When a plant with yellow and round seeds is crossed with a plant having yellow and wrinkled seeds, the progeny showed segregation for all the four characters. The probability of obatining green round seeds in the progeny of this case is

Out of the seven characters of pea studied by Mandel, genes for three were situated on the chromosome number four (flower position, pod shape and plant height). Suppose if they were closely situated and were linked, then which of the following rule would not have been discovered or explained by Mendel?

Mohini, a resident of Chandigarh went to Shimla with her parents. There she same plant that they have in their backyard, at home. However, she observed that while the plants in their backyard bore white flowers, those in Shimla had pink flowers. She brought home some seeds of the plant from Shimla and planted them in Chandigarh. Upon performing self breeding for several generation she found that the plant from Shimla produced only white flowers. (a) According to you what might be the reason for his observation-genetic or eavironmental factors ? (b) Suggest a simple experiment to determine whether this variation is genetic in nature (c) Suggest another experiment to check whether this variation in flower color is due to environmental factors
