The number of phenotypes produced for a given trait depends on how many genes control the trait. Anyhow, The distribution of phenotypes for a typical polygenic trait can often be expressed as a bell-shaped curve.
Many traits are controlled by two or more genes and are, therefore, called polygenic traits<span>. Each gene of a polygenic trait often has two or more alleles. As a result, one polygenic trait can have many possible genotypes and phenotypes.</span>
Acceleration (a) is the change in velocity (Δv) over the change in time (Δt), represented by the equation a = Δv/Δt. This allows you to measure how fast velocity changes in meters per second squared (m/s^2). Acceleration is also a vector quantity, so it includes both magnitude and direction.

The best way to do a observation can be a microscope or by taking notes ,and by , taking pictures or, asking questions about the subject that you and the teacher or you, your teacher and the class is talking about .! Hope this helps ..
Answer:A man with pku marries a woman without any alleles for pku.There is little possibility that a child will inherit PKU
<u>Explanation: </u>
PKU Is Phenylketonuria results in less metabolism of amino acid. It might lead to a mental disorder or behavior problems. It is mostly Genetic.
If only one parent is suffering from it then there is little possibility that it will pass on to a child but if both the parents are having the problem of PKU then there are more chances that the child will also develop such a problem. It can be treated if we catch it at an early stage.
