When 50% of all offspring are recombinants, geneticists say there is a 50% frequency of recombination.
A 50% frequency of recombination is observed for any two genes that are located on different chromosomes and are therefore unlinked.
This is a result of independent assortment. When two genes are close together on the same chromosome, they do not assort independently and are said to be linked.
Answer:
At about 50 kilometres (30 miles) below the Earth's surface, density measurements reach 200,000 pounds per square inch (13,790 bars). Due to the pressure from the above crust and mantle, lithosphere density generally increases as both age of the surrounding rock and depth increase.
Explanation:
The pressure values range from one to two times the lithostatic values (1ρgz to 2ρgz).
Civilization is most commonly defined along the lines of an advanced state of human society containing highly developed forms of government, culture, industry, and common social norms.
Federalism often refers to the beliefs of the Federalist party. This political party believed that the United States needed a strong federal (aka central) government in order for society to run well. This was based of several different factors including the lack of success of the Articles of Confederation (which had created a weak central government) and Shay's Rebellion.
On the other hand, people against the idea of federalism were worried that the federal government would gain too much power. Instead, they preferred for state governments to have a majority of the power. They used the American Revolution as their reasoning as to why a strong central government would not work well in America.
