Question

Gregor Mendel raised and observed pea plants. In his observations he noticed that some pea plants were tall and some were short. Some plants produced round peas and some produces wrinkled peas. Mendel noticed that different combinations of these traits occurred in each generation. What is the BEST explanation for this variation in pea plants?

Answer 1

when Mendel testing on pea plants in his lab he saw that some plants are tall, some are green, some are dwarf, some are yellow, some peas are round &so on, then he says that when dominant characters cross with dominant characters then dominant character will formed, when dominant characters cross with recessive characters then dominant character will formed &when recessive characters cross with recessive characters then recessive characters will formed then he gave these four laws
a) law of Dominancy
b) law of paired factor
c) law of sagrigation
d) law of inheritance
these laws says that gametes are found in paired form, when parent's gametes were crossing with each other then in f1 generation all progenies are hybrid dominant &in second generation their phenotype ratios are 1:2:2:4:1:2:1:2:1 &genotype ratios are9:1:2:1 means both dominant and recessive characters are found in f2 generation
