Answer:
Founders Effect
Explanation:
Occurs when a few individuals start, or found a new population. by chance, allele frequencies of the founders maybe different from allele frequencies of the population they left.
Answer:
alleles of a gene separate from each other during meiosis.
Explanation:
Mendel observed that the F1 expressed only one of the alternative variants (in this case, only rounded seeds appeared), while the other variant (wrinkle) disappeared. Mendel named "dominant" the expressed variant. Mendel allowed auto pollination and observed that in the second generation, F2, the other disappeared variant reappeared. Both alternative variants were present in the F2. Mendel named "recessive" the second alternative variant.
Mendel thought that hereditary traits determined by discrete factors were the possible explication for these phenotypes. These factors should have been present in the F1 in pairs. One of them came from one parental plant, and the other factor came from the other plant. These factors then separated again when sex cells were produced, giving two types of gametes, each with only one factor.
Mendel concluded that each individual (plant) has a pair of factors (alleles), one for each trait (R and r) and that the pair separates (<u>segregates</u>) during the formation of the gametes. This conclusion is known as the segregation principle (First Mendels´ Low).
Answer:
The preamble sets the stage for the Constitution, It clearly communicates the intentions of the framers and the purpose of the document. The preamble is an introduction to the highest law of the land; it is not the law. It does not define government powers or individual rights.
Establish Justice is the first of five objectives outlined in the 52-word paragraph that the Framers drafted in six weeks during the hot Philadelphia summer of 1787. They found a way to agree on the following basic principles:
"We the People of the United States, in Order to form a more perfect Union, establish Justice, insure domestic Tranquility, provide for the common defense, promote the general Welfare, and secure the Blessings of Liberty to ourselves and our Posterity, do ordain and establish this Constitution for the United States of America."
