A single gene could be inserted into a plant's genome, enabling specific traits to be expressed easily. Scientists have identified genes for two enzymes needed to make pro-vitamin A. One of these genes comes from corn.
In biology, a mutation is the permanent alteration of the nucleotide sequence of the genome of an organism, virus, or extrachromosomal DNA or other genetic elements. Mutations result from errors during DNA replication or other types of damage to DNA, which then may undergo error-prone repair, or cause an error during other forms of repair, or else may cause an error during replication. Mutations may also result from insertion or deletion of segments of DNA due to mobile genetic elements. Mutations may or may not produce discernible changes in the observable characteristics of an organism.
Answer:
Answer explained below
Explanation:
quantitative inheritance results in a continuous range of multiple phenotypes. The final phenotype results from both gene and environmental influences. For example, human height
WHILE
Qualitative inheritance results in distinct and separate phenotypic categories. The final phenotype results from gene action. For example, fruit fly eye color.
Jane Goodall was making observations on chimpanzees.
<u>Explanation: </u>
Jane Goodall spent years with the chimpanzees of Gombe. It all started when she found a chimp who was hungry and wonderfully used a twig of the branch to take the termites of the tree and feed on it. Goodall was fascinating to see a chimp think and behave like a human.
She observed the animal so closely and took note of each behavior. She was so passionate about the chimps that she overcame all the hurdles to find out the redefined mankind.
