What would the phenotype be for an individual who is heterozygous
B = brown eyes b = blue eyes

The phenotype would be brown eyes.

Explanation:

Dominant alleles always show up above recessive alleles. since brown is dominant brown will show.

it would be B = brown eyes

the way i look at this is when the symbol is capitalized it's dominant! and when it's lowercase, it's recessive. :)

hope this helps!

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.

i would say it is
