Astudent analyzed ears of corn that demonstrated two traits in the f2 kernels, purple or white colors and smooth or wrinkled shapes. a tabulation of 135 individual kernels gave the following results:
purple and smooth = 75
white and smooth = 28
purple and wrinkled = 24
white and wrinkled = 8
how many phenotypes are present?
a-2 ; b-3 ; c-4 ; d-6

C is correct, it was a lucky guess for me XD

Answer : The correct answer is C) 4

Phenotype is defined as the physical appearance or morphological form of the organism. It is determined by genotype ( genetic makeup) as well as the environmental factors.

As per the question, two traits of corn are analyzed that is color and the shape of the kernels.

In the given data of 135 individual kernels, there are four different phenotypes, which are purple and smooth, white and smooth, purple and wrinkled, white and wrinkled.

Thus, the correct answer is C) 4.

creative diagnostics provides a protocol for total protein extraction based on ripa which is widely used.

in 1859, charles darwin set out his theory of evolution by natural selection as an explanation for adaptation and speciation. he defined natural selection as the "principle by which each slight variation [of a trait], if useful, is preserved".
