Answer:
The suitable statement will be - only one allele appears for that gene in that population.
Explanation:
- Gene Fixation is a topic of population genetics. It means that fixing the change in a gene from a gene pool and that leads to express only one allele for that gene which only remains after the fixation process, in that population. Normally a gene exists of at least two variants or alleles.
- An allele fixation means that only one variant or allele will be expressed in all the populations.
Answer: 3
Explanation:
All elements in group 3 have 3 levels of energy.
Na (sodium) has 3 valences the inner has 2 electrons, the middle has 8 electrons and the outer has 1 electron.
This will continue across the group 3 adding one more electron to the outer valence until Ar (argon).
Remember the Octet rule of 8..?
