Answer:
If slim shelled snails have dainty shelled posterity and thick shelled snails have thick-shelled posterity then this is a decent proof that shell thickness is heritable.
In the genuine investigation they have watched however at first the number of inhabitants in snails had an arbitrary conveyance of shell thickness in the long run the nearness of a crab the predator lead to the determination of thick-shelled snails with the end goal that they are not consumed.Thickness of the shell is certain a heritable factor by qualities yet the choice or development of thick-shelled snails over the time is an unadulterated choice.
As the flower takes water that it needs to survive, the dye in it has no more density so it goes up with the water dying everything in its path blue.
Answer:
b. Craig is right and doesn't have to pay child support.
Explanation:
ABO blood group is controlled by three alleles. IA and IB are codominant to each other and both are dominant over i allele. IAIA and IAi produce A blood group. IBIB and IBi produce B blood group. ii produces O blood group.
Susan's son has O blood group so his genotype must be ii. He got one "i" allele from Susan and one "i" allele from his father. Craig's genotype is IAIA so there is no chance that he could have passed on "i" allele to Susan's son. Hence Craig is not his father and does not need to pay child support.
