Analyze the results of a cross between two organisms that are both heterozygous for two different genes (AaBb). Use a Punnett sq
strojnjashka [21]
(1) All the genotypes are as follows: AABB, AaBB, AABb, AaBb, aaBB, aaBb, AAbb, Aabb, aabb.

(2) Assuming that Aa is dominant and Bb is recessive, there will be 9 phenotypes with both A and B allele dominant (i.e. AaBb, AABb); there will be 3 phenotypes with just the A allele dominant (i.e. Aabb, AAbb); there will be 3 phenotypes with just the B allele dominant (i.e. aaBb, aaBB); and there will be 1 phenotype with both alleles recessive (i.e. aabb). The phenotypic ratio in this case is 9:3:3:1.

(3) The probability of producing an offspring with the aabb genotype is 1/16 or 6%.

lorasvet [3.4K]

The correct answer is - b. make their own food.

The plants are differing from most of the other organisms in that that they produce their own food. In order to produce their own food, the plants use the sunlight, carbon dioxide, water, and nutrients from the soil. They manage to perform a process called photosynthesis in which they manage to turn those things into sugars, thus create their own food. That makes the plants producers, which puts them on the bottom of the food chain, meaning they are the basis and most important part of the ecosystems in which they exist.
