Answer: B (Color blindness)
Explanation:
Typical red-green color blindness in human patients is caused by mutations on genes located in the X chromosome. These mutations act in a recessive manner. Since females have two X chromosomes, the presence of a mutation in a single one of them does not normally result in color blindness. Males, in contrast, have a single X chromosome and therefore the presence of a mutation is likely to cause the disease.
About the other options: Down‘s syndrome is a numerical chromosomal anomaly, not related to sex. Human blood type is a codominant trait. Finally, tail length in dogs is a polygenic trait not amenable to classic Mendelian analysis.
Globin 1 and globin 2 genes of insects are understood to have diverged approximately 170 million years ago, through duplication, from a common globin gene ancestor. The two genes that code for haemoglobin have conserved regions; oxygen-binding and heme- regions. Globin 2 gene has lost the intron region that is still present in the globin 1 gene. The percentage divergence is 7.2% with 20 varying nucleotides.
MRNA is responsible for carrying coded information from the nucleus.... i hope you it will help you.... :)
Answer: The main function of Cellular respiration is to convert glucose into energy source (ATP).
Explanation: Cellular respiration is process in which chemical energy of food is released and turn into ATP. This process incudes three steps: Glycolysis, Kreb Cycle and electron transport chain.
Glucose can not be directly used as energy. By the process of Cellular respiration 1 glucose molecule gives 38 ATP molecules.
