Answer:
The most appropriate answer would be b. gene flow at work.
Transfer of pollen grain forms the example of vertical gene transfer that is, transfer of a gene from parent to the offspring.
A pollen grain is the male gamete of the parent plant. It contains the genetic material or information of the plant.
It is pollinated or transferred to the stigma of the plant of same species with the help of air, water, bees et cetera. Successful pollination results in the formation of the zygote.
Thus, gene or genetic material is transferred from parent plant to the offspring. Hence, the student can use "gene flow at work" as the caption of the picture.
The last one is C..............
Answer:
gametes
Explanation:
In the human reproductive process, two kinds of sex cells, or gametes (GAH-meetz), are involved. The male gamete, or sperm, and the female gamete, the egg or ovum, meet in the female's reproductive system. When sperm fertilizes (meets) an egg, this fertilized egg is called a zygote (ZYE-goat).
Answer:
The answer isn't on there, but humans have estimated 20,000-30,000 genes.
<em>The</em><em> </em><em>closest</em><em> </em><em>answer</em><em> </em><em>in</em><em> </em><em>the</em><em> </em><em>selection</em><em> </em><em>is</em><em> </em><em>"</em><em>Twice</em><em> </em><em>as</em><em> </em><em>many</em><em> </em><em>as</em><em> </em><em>A</em><em>"</em>
Explanation:
The HGP has revealed that there are <em>probably about </em>20,500 human genes. This ultimate product of the HGP has given the world a resource of detailed information about the structure, organization and function of the complete set of human genes.
Each chromosome contains hundreds to thousands of genes, which carry the instructions for making proteins. Each of the <em>estimated </em>30,000 genes in the human genome makes an average of three proteins.
