Answer:
Yes.
Probability of such child = 1/2 or 50%
Explanation:
According to the question, below are the genotypes and phenotypes possibilities:
aa = normal vision & no headache
Aa = normal vision & no headache
AA = blindness & headache
Male Female
Aa aa
Possible genotypes of progeny: Aa Aa aa aa
So it is clear that out of the 4 probable children, 2 with 'genotype aa' will have normal vision & no headache.
Mathematical expression is as under:
2/4 = 1/2 that means 50% progeny.
It is a cold Artic air mass over Siberia. Air masses are altered because it doesn't stay in one place and changes as it moves due to the temperature of environment that can be caused by moisture. The cold Artic Mass from Siberia will go to the North Pole, Canada then moves further to the South area.
An enormous rift in one of Antarctica’s largest ice shelves grew
dramatically over the past month, and a chunk nearly the size of
Delaware could break away as soon as later this winter, British
scientists reported this week.
If
this happens, it could accelerate a further breakup of the ice shelf,
essentially removing a massive cork of ice that keeps some of
Antarctica’s glaciers from flowing into the ocean.
Answer:Cleft chins were believed to be a dominant trait: if two parents had cleft chins, their kids could have a cleft or might not But it turns out a cleft chin is too complicated to be simply dominant. Two parents without a cleft have kids with cleft chins way more often than predicted with this simple model.
