Rose comb (R) in chickens is dominant over single comb (r). Cross a white heterozygous rose comb chicken to a black single comb chicken.

What is the genotype of the white heterozygous rose comb chicken?

What is the genotype of the black, single combed chicken?

What fraction of the offspring will be blue rose comb?

What fraction of the offspring will be blue?

What fraction of the offspring will be single comb?

What fraction of the offspring will be white rose comb?​

brown

explanation:

both anaerobic and aerobic respiration use glucose (or other carbohydrates), proteins and lipids to produce atp and nadh. cell uses those energy molecules, obtained from food and   breaks them down during the chemical reactions of respiration. in anaerobic respiration, nadh is regenerated to nad+ by enzymes lactate dehydrogenase (lactate is produced, e.g. in muscle cells) or by alcohol dehydrogenase where ethanol is produced (alcohol fermentation), while in aerobic respiration, electrons from nadh are deposited in the mitochondria to regenerate nad+ (electron transport chain. anaerobic respiration produces 2 atp per molecule of glucose compared to aerobic respiration where about 38 atp molecules are produced.

•there must be variation for the particular trait within a population.

•the variation must be inheritable (that is, it must be capable of being passed on from the parents to their offspring).

•individuals with one version of the trait must produce more offspring than those with a different version of the trait.good
