the fertilization of ovules from plant Q by pollen from plant R results in the productions of seeds. What percent of the genes i

Helga [31]

Answer:

The correct answer is - zero or 0%.

Explanation:

The fertilization in flowering plants takes place by fusing the pollen of one plant or flower with the ovum of another plant or flower of the same species normally and form a zygote. The zygote gets an equal amount of genetic material from both parent plants by the process f exchange of the genetic material.

The ovum or the egg cell of the plant is considered as the mother and the mother is responsible for the chloroplast And mitochondria of the progeny so in this case, the ovum and egg cell comes from the only plant Q thus, the percentage of chloroplast genes provided via Plant R is 0%.

Attached is the image respective of the question.

First, both the extracellular fluid and the cytoplasm are hydrophilic. The phosphate head of the phospholipid is hydrophilic hence it either faces the extracellular fluid and the cytoplasm. The lipid tail of the phospholipid is hydrophobic hence it is confined in the middle of the plasma membrane. Both cytoplasmic and the extracellular fluid ends of the transmembrane protein are hydrophilic and the middle part of the transmembrane protein is hydrophobic.
