A woman and her husband both show the normal phenotype for pigmentation, but both had one parent who was albino. Albinism is an autosomal recessive trait. Their first two children have normal pigmentation. What is the probability that their third child will be an albino

it depends on how much it could carry.

the last one: artificial selection/genetic engineering

plant breeding is modifying the genetic composition of the plant - but this isn't cloning (which is specifically introducing a gene into a genome). but you are artificially selecting for the phenotype that you want.

the second one is literally genetic engineering - the gene would have been cloned first and then inserted or genetically engineered into the new plant cell (the cotton).

its b. greenhouse gasses trap uv rays for heat so that the plants stay alive.
