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%

So the answer is point A
The following given statements are true of trans-fatty acids:
A. Often created by treating plant oils with hydrogen
D. Occur naturally in in food
<u>Explanation:</u>
The unsaturated fatty acids that are produced by a method called hydrogenation through the addition of a hydrogen molecule to vegetable oils is understood as "Trans-fatty acids". According to the hydrogenation process the composition of the fatty acids varies. The unsaturated fatty acids trans structure receives one double conjugated bond and obtains a straight shape and rectifies the twisted shape created by cis bonds.
Increasing the concentrations of trans-fatty acids particularly in the red blood cell membranes can lead to blockage of the blood vessel as a whole and enhance the risk of heart disease. Meat and dairy products kind natural food materials include trans fatty acids.
