Which of the following phenomena is a consequence of Independent Assortment? 1. Pure breeding plants, when mated with each other
, produce completely homozygous offspring. 2. For any gene displaying complete dominance, heterozygous individuals exhibit the dominant phenotype. 2. Smooth seed trait is dominant to wrinkled seed trait in peas. 4. The phenotypic ratio among phenotypes produced from an F1 X F1 dihybrid cross is 9:3:3:1.
Answer: The outcome of the phenotypic distribution resulting from an F1 X F1 dihybrid cross is 9:3:3:1.
Explanation:
The independent assortment of genes clarifies how alleles situated on various chromosomes segregate independently of one another during the formation of gametes.
Therefore, a dihybrid cross involving TWO traits (e.g. seed color and seed shape) will have its associated alleles DISPERSING, regardless of being dominant or recessive, leading to a varied proportion of offspring in the classic ratio of 9:3:3:1; which is a direct result of the independent assortment principle.
If this were indeed accurate, it would threaten the internal balance of our cells; akin to how not all keys fit in locks, not every molecule possesses the "key" needed to transport across the phospholipid bilayer into and out of the intracellular and extracellular fluids. Typically, small hydrophobic ("water-repelling") molecules can traverse this bilayer.
The potato does not increase in size because it is only a segment of the plant. Water absorbed from the soil is taken up by the roots and transported to other parts like leaves, but the potato itself does not directly absorb water from the soil.
