What is genetic equilibrium? what conditions are required to maintain genetic equiibrium?
Anna35 [415]

The genetic equilibrium represents the condition of a genotype or an allele in the genetic pool of a particular population, where there are no changes in the frequency in the successive generations. This basically means that the population has managed to reach the peak of its evolution for the environment in which it leaves, so there's no evolutionary pressure for changes.

In order for the genetic equilibrium to be maintained for prolonged period of time, the population should not face any evolutionary pressure that will cause changes in it. In essence, this means that the environment in which the population lives should remain exactly the same as it is for longer period of time, so the population will have no need to change its appearance or behavior.

vesna_86 [32]
 You need to create a table like the one below and show that, if crossed, these two dogs would create 100% wire-haired dogs, but with smooth genotype. They will be heterozygous wire-haired, because the wire hair dominates over the smooth hair.

The genotype is the genes you can't see, and phenotype is what you can see. So some traits can just be in your genotype, so you don't have them but your children can get them. If there are two different traits in your genes the dominant ones will win and will be the ones you see. There needs to be two recessive genes for that gene to win. I hope this was clear. It's a little complicated!
