In pea plants P represents purple flowers while p represents white, and T represents tall plants while t represents short. Biologists cross two pea plants, each with the genotype PpTt.

We would expect what phenotypic ratio from this dihybrid cross?
A) 1:1:1:1 ratio
B) 9:3:3:1 ratio
C) all dominant for both traits
D) all recessive for both traits

B) 9:3:3:1 ratio

Explanation: A dibybrid cross between two pea plants of genotype PpTt, will produce 16 offsprings, 9 of the offsprings will be purple and tall, 3 will be purple and short, 3 will be white and tall while 1 will be white and short.

as resources become scarce because of population growth, the growth decreases after few years due to lack of resources and food.

the cells uses some of the atoms of the glucose molecules to atp molecules. the atoms of the glucose molecules will then be converted into energy which will be eventually stored in atp. the energy produced which are stored in atp are coming from the glucose’s chemical bonds.
