Complete the graphic organizer to summarize exceptions to Mendels principles
Butoxors [25]

Answer:

<em>Exceptions to Mendel's principles: </em>

Does exceptions mean that Mendel was "wrong"? The answer is "NO". It means that we know more today about diseases, genes, and heredity than compared to what he expalined 150 years ago. Here I have summerized the exceptions with examples:

<em>Incomplete dominance</em>: When an organism is heterozygous for a trait and both genes are expressed but not completely.

<em>Example</em><em>:</em> SnapDragon Flowers

<em>Codominance</em>: When 2 different alleles are present and both alleles are expressed.

<em>Example</em>: Black Feathers + Whites feathers --> Black and white speckled feathers

<em>Multiple alleles</em>: Three or more alternative forms of a gene (alleles) that can occupy the same locus.

Example: Bloodtype

<em>Polygenic traits</em>: more than one gene controls a particular phenotype

Example: human height, Hair color, weight, and eye, hair and skin color.

What do high and low air pressure systems mean in terms of density?
Arada [10]

<span>There are two physical differences between Low pressure systems and </span>High pressure systems.

First, is the circulation surrounding them.

Secondly, is the atmospheric motion that they cause.

Low pressure systems circulate counter-clockwise. High pressure systems circulate clockwise. These "motions" are the building blocks in our atmosphere. They give us our weather.

A Low’s counter-clockwise circulation forces air upward (ultimately resulting in condensation, cloud formation and ultimately precipitation). A High’s clockwise circulation causes a sinking motion in the atmosphere, resulting in fair/clearer and often sunnier skies.
