" Consider the following pedigree of a rare, autosomal recessive trait called phenylketonuria (PKU). Shaded individuals have the disease which involves the inability of a person to break down the amino acid phenylalanine. Left untreated, it results in profound mental developmental delays. In the USA, the disease is observed in the population at a rate of 1 in 14,000. Apply the inbreeding convention where required. If individual B chooses to marry someone from the general population, what is the probability that the couple has an affected child

i think that the best answer would be c.

tell me if im wrong : )

the answer is; comparing the frequency of collisions with and without the device

this makes the anti-collision system an independent variable and the collisions a dependent variable. if there are fewer collisions with an anti-collision system that without, then it can be stated that the system is a success. essentially, collisions under an anti-collision system are compared with the frequency of collisions by cars with the human drivers.

1. loamy sand is about 80% sand with 10% clay and defined mostly by sand particles with some clay to provide structure and fertility. the sand particles are easily visible and the soil holds structure but breaks apart easily.

2. scott sand can improve his soil quality by incorporating more silt and organic matter into the soil. peat moss and organic matter can also be incorporated.

any abiotic or biotic factor in an ecosystem that causes a population's size to slow or decrease is a limiting factor.
