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 nurse is teaching a new group of mental health aides. The

Point source outbreak is a condition in which people are exposed to the same source of infection from a pathogen. This may occur due to the consumption of a single meal which is being infected by the pathogen. This may lead to incidences of food poisoning, disease and even mass death.
The oldest fossils present at the bottom of rock layer whereas the youngest fossils are present in the top layer.
<h2>Rock layers from oldest to youngest</h2>
The rock layers that is located farthest from the ground surface are considered as the oldest rock layers and rock layers that are closest to the ground surface are considered as the youngest. A fossil is the remains or traces of plants and animals that lived long ago.
<h3>Presence of fossil</h3>
Those fossils which are present at the bottom of the rock layers are considered as the oldest fossil followed by the upper layer's fossil and so on. The fossils present at the top layer are the youngest fossils so we can conclude that oldest fossils present at the bottom of rock layer whereas the youngest fossils are present in the top layer.
