What is a trait or genetic disorder caused by Polygenic inheritance?
A polygenic trait is a trait which multiple genes affect. An example would be skin color, the combined affects of several genes determine your base pigment shade. Polygenic traits are caused by a combination of genes.
Explain how stabilizing selection would affect a graph of the distribution of phenotypes for a trait?
I would make the graph narrower.
What are the homozygous letters of a tall parent?
Uhh.. theoretically, if you were to represent a tall parent's genotype they would be something like TT, but it's much more complicated than that. Height is a multifactorial polygenic trait that can't be expressed as a single genotype, practically.
What is the relationship between dominant and recessive alleles in a heterozygous organisms?
it means there is one of each. in a homozygous gene it means that there are two of the same. for example if "t" repressents a recessive trait and "T" represents a dominant trait, then an organism with a gene that is tT would be considered heterozygous, and a gene that is TT or tt would be considered homozygous or "pure bred"
What is continuously varying trait?
A discontinuous trait is the opposite of a continuous trait. They are "either/or" traits that do not have any range. An example would be the sex of an offspring, whereas an example of a continuous trait would be haircolor, where many options are available.

What is it called when more than one set of genes controls a trait?
yes it could......... when it happens its called polygenic inheritance

I would make the graph narrower.
What are ways in which natural selection operates on ploygenic traits?
Polygenic? Natural selection usually acts on the phenotype of polygenic traits as they are suites of genes acting in concert to form a trait. If you had a trait, such as height, in two variant brothers then the aggregate would need to be selected for as the genes working in concert, but not equally well, would render different heights in the brothers which would be then visible to natural selection.
The graph below represents the amount of change Jaxon would receive, y, if he bought a item with a cost of x?
there is no graph i dont see it
Which graph best represents the snowboarder from point 2 to 3?
It would help to have the graphs to choose from!
What feature of a distance ortime graph represents speed?
slope of the graph ... actually the absolute value of the slope, actual slope, positive or negative, would indicate direction, so the slope would be velocity.
What would be your clue that a character would have polygenic inheritance pattern?
Polygenic inheritance shows a continuous variation. An example of polygenic inheritance is human skin because it has a variety of colors. An example of something not having polygenic phenotype is earlobes because they are either free or attached; there is no in-between state.
What is a trait expressed when two different genes for the same trait present?
If the two different genes include one dominant allele and one recessive allele, which is the heterozygous genotype, the dominant phenotype is expressed. For example, if R represents the red flower allele and r represents the white flower allele, the flowers would be red. If the trait is governed by incomplete dominance, then the heterozygous genotype (Rr) will produce an intermediate phenotype, such as pink.
How would a graph of negative and positive acceleration differ?
This depends on what the graph represents. If it is a graph of velocity on the vertical and time on the horizontal, then if acceleration is at a constant rate, the graph will be a straight line with positive slope (pointing 'up'). If acceleration stops, then the graph will be a horizontal line (zero acceleration or deceleration). If it is deceleration (negative acceleration), then the graph will have negative slope (pointing down).

Does a pie graph have to have a title?
Certainly, you should choose a title which states what the information in the pie graph is all about. It would also be good to give some indication of what each piece of pie represents; easily done by using coloured pencils with a "table" telling what each coloured section represents.
