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.
Answer:
La célula es una estructura constituida por tres elementos básicos: membrana plasmática, citoplasma y material genético (ADN). Las células tienen la capacidad de realizar las tres funciones vitales: nutrición, relación y reproducción (ver t13). La forma de las células está determinada básicamente por su función.
Nitrogen, phosphorus and potassium, or NPK, are the “Big 3” primary nutrients in commercial fertilizer
Answer:
1. BB x bb
2. 100% black
Explanation:
Heterozygous offspring would have the genotype Bb. In order to produce offpsring that are 100% heterozygous, that means each parent must be homozygous. Therefore, the genotypes of the parents are BB (black rabbit) and bb (white rabbit). See punnet square attached.
The phenotype refers to the expression and display of the genotype. We will assume that because black is denoted by a capital B, and white by a small b, that black is the dominant allele. Therefore, if 100% of the offspring have the genotype Bb, then 100% of the offspring have the phenotype of black fur.
It is known as ISCHEMIA.
Ischemia occur when there is an hindrance in the flow of blood to a particular organ in the body. Because it is the blood that carry oxygen round the body, such an organ will not get adequate supply of oxygen. Ischemia is usually caused by blockage or narrowing of the arteries.
