The fertilization of ovules from Plant Q by pollen from Plant R results in the production of seeds. What percent of the genes in each offspring's chloroplasts will have been inherited from plant R? A: 0%

B: 25%

C: 50%

D: 100%

The correct answer is - option A. 0%

Explanation:

The zygote formation or fertilization in flowering plants occurs by the fusion of pollen of one plant with the ovum of another plant of the same species normally. This process includes the exchange of an equal amount of the genetic contribution from both plants.

The egg cell of the mother is responsible for the mitochondria and chloroplast of the progeny so the percentage of chloroplast genes provided via Plant R is 0% as ovum and egg cell comes from only plant Q.

percentage of chloroplast gene inherited from R plant is a)0%

correct answer is option a.

tropopause, stratopause and mesopause have all in common aspect that is point of maximum temperature in its layer of the atmosphere. all layers of atmosphere observe abrupt change in temperature. tropopause is the boundary between troposphere and stratosphere. stratopause is the boundary between stratosphere and mesosphere. mesopause is the boundary between mesosphere and thermosphere. these all boundaries are ranges between altitude of 0 to 80 km.

i believe it is "they are not used up by reactions" as the answer to your question, text me back if this is correct because i just learned this.
