When Mendel crossed a plant homozygous for round seeds to another plant homozygous for wrinkled seeds, he found that all the pro
deff fn [24]

Answer:

a. The allele for round seeds is dominant to the allele for wrinkled seeds.

Explanation:

Mendel found that when two pure breeding plants that differ from each other with respect to one genetic trait are crossed, all the progeny express the phenotype of one parent. The phenotype of the other parent is not expressed in the progeny. He concluded that the genetic trait that is expressed in the F1 generation is dominant over the other which is masked in this generation.

A cross between pure breeding plants for round seeds and the wrinkled seeds obtained all the round seeded progeny. This meant that the phenotype "round" was dominant over the phenotype "wrinkled". If the allele "R" gave round phenotype and the allele "r" imparted wrinkled phenotype, the allele "R" was dominant to the "r".

Define brain death, agonal phase, clinical death and mortality.
OleMash [197]
  • Brain death: is the legal definition of death. It is the complete and irreversible stop of all brain functions. This means that as a result of severe aggression or severe brain injury, the blood that comes from the body and supplies the brain is blocked and the brain dies.
  • Agonal phase: occurs with the realization of the preceding events when life is about to break free of the protoplasm, because the protoplasm cannot sustain it for long.
  • Clinical death: is defined by the cessation of electrical activity in the brain, resulting in irreversible and total loss of neurological activity in the brain and brainstem. When doctors officially declare a person's clinical death, it means there is no cure or return to recovery.
  • Mortality: It is the condition of being mortal, therefore, of being susceptible to death. However, the term mortality is in most cases related to the statistical studies applied on populations. So mortality appears as a number that seeks to establish the number of deaths over a given population.
