What is the expected phenotypic ratio for a one-factor cross of two hybrid organisms?

1 answer:

6 0

You would expect a 3:1 ratio of dominant to recessive.
Two heterozygous, or hybrid, organisms with the genotypes, say, Aa, could yield these 4 offspring: AA, Aa, Aa, and aa. The first 3 have dominant phenotypes, and the last has recessive.

dangina [55]

Answer: Lysosomes

Explanation:

Lysosomes is the type of organelles which contain enzymes that breaks down the various fatty acids. As, these enzymes basically work in the less oxygen areas and the low PH region. The peroxisomes absorbed all the nutrient from the cell and they are degraded from the sub-cellular structure.

The lysosomes is the single membrane that contain the digestive enzymes for breaking all the toxic material such as fatty acids, ethanol and hydrogen peroxide in cells.
