1.The trait is recessive. This means both your parents were carries, but did not show the trait. For example, B represents the allele, you're parents would have to both be Bb. This means that they are carriers, and you could have inherited either BB/Bb/bb - you actually inherited bb, which means because its a recessive trait you will show the trait.
2. For your children, it depends on who you have them with. Because you're bb, you will definitely pass on the b allele, so any child you have would be a carrier and could potentially have the trait. If you have a child with someone BB, all your offspring will be Bb (carriers- as the kid gets one allele form each parent). If you have a child with someone who is bb, all your kids would definitely have the trait. However, if you have a child with someone who as Bb, then the four outcomes are Bb Bb bb bb, so there would be a 50% chance of your kid having the trait.
d. A purine base forms hydrogen bonds to pair with a pyrimidine base located on the opposite DNA strand. Specifically, A pairs with T, and C pairs with G.
The vertical migration of <em>Daphnia sp.</em> is their characteristic behaviour.
These organisms migrate to the surface of the water body during night and remain at the bottom during the day.
Behaviorists believe that <em>Daphnia sp. </em>does this to avoid predation.
During the day, it remains at the bottom that lacks light and avoids being noticed by the fishes. But at night when the day light is absent it swims up to feed upon the algae present in the clear surface water.
Thus we can conclude <em>Daphnia</em> population is responding to the clarity of water.
