Answer:
2 (tall) :2 (short) or 1:1.
Explanation:
Mendel is known as the father of genetics. He explains the laws of segregation and the laws of independent assortment by working on the pea plant <em>Pisum sativum.</em>
The height of tall pea plant be T and the short pea plant be t. The cross between heterozygous dominant tall pea plant (Tt ) and short pea plant (tt) is as follows:
Parents Tt × tt
The progeny obtained from the cross are Tt, tt, Tt and tt.
Two tall pea plants and two short pea plants.
Thus, the phenotype ratio is 1:1.
Answer:
crossing the plant to one you know has the recessive trait
Explanation:
<u>The correct procedure would be to cross the identified plant with the same plant that has the recessive trait.</u>
<em>The phenotypes of the progeny from the cross will give an indication of the dominance or recessive of the phenotype. If all the progeny from the cross produce the same flower color as that of the identified plant, it means the phenotype is dominant. Otherwise, it is recessive. </em>
The procedure is called test-crossing in genetics.
Dopamine is a neurotransmitter that is related to the positive feedback/reward system of mammal brains. Higher amounts of dopamine released in response to any stimulation will result in a stronger desire to recreate that stimulus. One could say that the extra dopamine released during drug use causes the brain to desire using the drug again to receive that same pleasurable reward sensation. <span />
