Kinesis because he is moving away from an external stimulus.

light dependant reactions
Explanation:

False.
In a dihybrid cross, the expected ratio of genotypes is 1:2:1:2:4:2:1:2:1.
In this example the ratio is 1:2:2:4:1:2:1:1:1. So, this ratio is false. It is expected 1<span>YYRR : 2YYRr : 1Yyrr : 2YyRr : 4YYrr : 2YyRR : 1yyRR : 2yyRr : 1yyrr.</span>
Answer:
The involvement of more than two genes.
Explanation:
The polygenic characteristics have many phenotypes because more than two genes governs the phenotype of individual organism. The single gene contains a pair of alleles that codes for two phenotype and two genes will code for 4 phenotype. Thus, more than two genes for example, three genes will have six phenotypes.
The skin color and height are polygenic characterstics in humans.
