in this punnett square, what is the ratio of homozygous to heterozygous offspring?

in the punnett square, what percentage of the offspring are homozygous recessive?

a) Ratio of homozygous to heterozygous offspring 1:1

b) Percentage of the offspring that are homozygous recessive 50%

Explanation:

When parents with genotype "Tt" and "tt" are crossed , the following offsprings are produced -

Tt

tTttt

tTttt

The hetrozygous offsprings produced in this cross is Tt

The homozygous offsprings produced in this cross is tt

So,  the total number of hetrozygous offsprings = 2

The total number of homozygous offsprings = 2

a)

Ratio of homozygous to heterozygous offspring

b)

Percentage of the offspring that are homozygous recessive

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.

the correct answer is c   with the systems
