That would be 1/16 which is 6.25%. The offspring have to be rryy.
There are 2 ways of thinking about this and other dihybrid crosses
—> the ratio of different genotypes is (9:3:3:1) for a dihybrid cross so the probability of wrinkled and green offspring is 1/16 (9+3+3+1=16)
—-> we can think of them as 2 monohybrid crosses. One RrxRr and one YyxYy. The probability of getting wrinkled(rr) is 1/4. The probability of getting green(yy) is 1/4. So the probability of wrinkled AND green is 1/4*1/4=1/16
The process is decomposition.
Decomposition is a process by which organic substances, like leaves, are broken down into simpler matter. A lot of different types of organisms, called the decomposers, will consume the organic substances(like dead plants, dead animals) and continue an essential part of the nutrient cycle. This is important for recycling the organic matter that occupies space in the biosphere.
B. From microorganisms that live in the soil.
Answer:
Mutations in that organism, which can possibly lead to cancer (via mutations in the proto-oncogenes or tumor-suppressor genes)
