Answer:
generation 1
Explanation:
The allele frequency is a term that represents the frequency that an allele can appear in a given population. This term can help to develop conclusions about the genetic diversity that a region presents in relation to the individuals that compose it.
In relation to the question above, generation 1 had the highest frequency of having one of each allele. This is because this generation presents the maximum frequency of the dominant and recessive alleles in a coherent way, 0.60 and 0.40. However, the other generations showed a steady and progressive decrease in the recessive allele.
Answer:
after it happens
Explanation:
A reflex action or reflex pathway is the pathway that gets activated in the condition or reflex or immediate situations.
During reflex action, the sensory signals are not sent initially to the brain which helps in analyzing the situation but the analysis and interpretation of signals are performed by the spinal cord (a part of CNS) interneurons.
After the motor signals are sent to the effector's muscles, the sensory signals from the spinal cord are then sent to the brain. Therefore, the role of the brain comes later and the brain then analyses that what happened during the reflex action.
Thus, after it happens is the correct answer.

The answer is <span> b) chromosomes replicate
DNA replication occurs before mitosis. So, duplicated chromosomes are already present in mitosis. They are connected by centromeres. During different phases of mitosis, spindles are formed and pull chromosomes toward the opposite poles of the cell so centromeres must split.</span>
