The dwarf male father with normal height is homozygous recessive for achondroplasia. The male of heterozygous for the character because this is autosomal dominant. He is also normal vision reason he is X-NY.
The women is color blind and normal height. The cross is X-NYAa x XnX naa. The father will produced gametes x-NA,X-Na , YA and Ya and the mother only gamete X-na. So the son of this type of couple is X-nYAa which can be color blind and dwarf and normal height.

Answer: The correct answer is rRNA and protein.
Explanation:
Ribosome is a cell organelle present in the cytoplasm of all living cells. It is a site of protein synthesis in all type of cells. It is made up of two sub-units namely, small sub-unit and large sub-unit.
Both the sub-units are formed by rRNA (ribosomal RNA) and associated proteins. rRNA is ribozyme, that is, it is a ribonucleic acid with catalytic ability. The protein component helps in providing the structure to the ribosome.
