Answer: probability that both twins are affected is 0.0625 while the probability that both twins are unaffected is 0.5625
Explanation:
If both parents are heterozygous for albinism, it means they both have one recessive allele (Aa) each.
The possible genotype outcome of one child will be
AA Aa Aa aa
Therefore the possiblility one child will inherit both recessive allele (aa) is 1/4 and the probability that one child is unaffected is 3/4
If the had a dizygoyic twins this means the two children have different DNA.
So also the possibility of the second child to inherit both recessive allele (aa) is 1/4
The probability that both the twins are affected is
1/4 * 1/4 =1/16 = 0.0625
The probability that both are unaffected is
3/4 * 3/4 = 9/16 = 0.5625

The largest organ in an earthworm is its skin
Answer: the absorption of water by the roots
Explanation:
Evaporation of water through the leaves is known as transpiration, and it occurs readily only when environmental conditions such as humidity is high.
On the other hand, the absorption of water by root hairs which is then conducted by the xylem vessels up the stem to various parts of the plant is a important process that determines how water move through a plant to ensure cellular processes such as photosynthesis, respiration etc takes place.
Thus, the absorption of water by the roots plays a much more important role in the movement of water in a plant
