Answer:
Monohybrid cross:
Monohybrid cross may be defined as the cross done by taking single trait at a time. The ratio of the monohybrid cross by the pure parent breed result in the formation of 3:1 phenotype in the second generation.The genotype ratio is 1:2:1.
Test cross:
Test cross may be defined as the cross between the unknown genotype and the recessive parents. This cross is done to determine whether the genotype is heterozygous or the homozygous dominant trait. The ration of the cross may vary depending on the genotype of the organism.
The correct answer is D - the father must be colorblind.
Colorblindness is a recessive trait, so in order for it to appear, you would need either one heterozygous and one homozygous recessive parent, two heterozygous parents, or two homozygous recessive parents.
Males only have one X chromosome to give to make a female. Their other chromosome is a Y. These sex-linked traits only appear on the X chromosome.
Since colorblindness is recessive, this X chromosome the father gives must be recessive, meaning <em>he must be colorblind.
</em>The mother can either be homozygous recessive (colorblind) or a carrier.

Explanation:
Photosynthesis involves carbon dioxide and water as the reactants, combining to form glucose and oxygen ( the products ).
Now there is dark photosynthesis and light photosynthesis, where light photosynthesis takes place first considering it converts carbon dioxide (CO2) and water (H2O) into carbohydrates. The ATP energy from the light photosynthesis helps the dark photosynthesis produce the sugars.
______________________________________________________
Cellular Respiration is simply the opposite. Taking the reactants and products into account, you could simply switch the two and the reactants of photosynthesis = products of cellular respiration, and vice versa. However, ATP energy is made in both. In fact Photosynthesis actually uses some ATP energy in it's chemical reaction...
Thus, we can conclude that Photosynthesis is quite the opposite of Cellular Respiration ( in terms of their chemical formula )
