The appropriate response is Zero degrees. The beam will leave the two mirrors along a way parallel to the one it came in on. This is the guideline of the corner reflector, which is frequently utilized as a radar target. Take note of that the corner reflector utilizes three reflecting surfaces (that are set up at 90o from each other) rather than the two like are being utilized here. Wikipedia has a truly awesome drawing that shows this two-dimentional issue pleasantly. A moment connection is given to the article on the corner reflector and the 3-D angles.
The parents genotypes can be described as incomplete dominance since each parent provides a different allele of the given gene and none is dominating.
Heterozygous genotype is a process where by an offspring inherits different forms of a particular gene from each parent. .
Looking at the Punnett square, it is oblivious that the offspring inherited different version of the parents genes. This is shown by the presence of the two different letters indicated as Tt for all the four boxes in the Punnett square.
Thus, we can conclude that each parent provides a different allele of the given gene and none of the parents gene is dominating.
