Answer:
Individual #1 would be ff >>>>>> Individual 14 would also be ff
Explanation:
Since ff is the recessive trait, and the recessive trait is being represented on this pedigree, it has to be ff. In addition, the offspring are recessive and normal. This means that 2 would be Ff. > Because the small f from 2 and the small f from 1 combined to make ff for the 4 individual. 3 induvial is just Ff.
Hope this helps!
Answer:
The founder effect may result in a population with a diminished gene pool, so there is a need to choose organisms with diverse genetic material.
In order to reduce the loss of any allele, preferential mating must be made between the organisms possessing rare alleles.
Inbreeding leads to reduced fitness as inbreeding occurs because of mating between the associated individuals, thus, there is a need to permit the least associated individuals to mate.
The captive-bred animals may exhibit reduced adaptation in wild, thus, they must be discharged into the wild prior passing of the generation.
The loss of learned behavior is generally associated with the acquired trait and does not associate much with genetics.
The right ventricle pumps the oxygen-poor blood to the lungs through the pulmonary valve. The left atrium receives oxygen-rich blood from the lungs and pumps it to the left ventricle through the mitral valve. The left ventricle pumps the oxygen-rich blood through the aortic valve out to the rest of the body.
It does not produce glucose. Oxygen reacts with the glucose to produce carbon dioxide and water and ATP.
