The allele for brown eyes is dominant and the allele for blue eyes is recessive. If two people who are heterozygous for the trait have a child,
what is the genotypic ratio for the offsprings?

. ph changes the ability of them he enzyme to dissolve in water.

the law of original horizontality explains:   why rocks appear in layers. correct answer: b the law suggests that all rock layers are originally laid down (deposited) horizontally and can later be deformed.   the principle is used by geologists to make assumptions about the relative ages of sedimentary rocks.

i believe it's c. the trait for large beaks will be passed on to future generations through natural selection.

since eventually smaller beaks would have to find another source of food or even eventually just die out from the lack of food.
