Answer:
9/16
Explanation:
This is a typical dihybrid cross involving two genes; one coding for anridia (form of blindness) and the other for Migraine headache, both in humans. The allele for possessing anridia (A) is dominant over the allele for not possessing it (a) in the first gene, while the allele for having Migraine headache (M) is dominant over the allele for not having it (m) in the second gene.
A cross between a man that is heterozygous for both genes (AaMm) and a woman also heterozygous for the two genes (AaMm), this means that both parents are dominant for the two traits i.e. they both possess anridia and migraine headache.
Both parent cells will undergo meiosis to produce four possible combination of gametes in which the alleles are independent of one another in the gametes, according to Mendel's law of independent assortment. The gametes are: AM, Am, aM, am
These gametes are crossed using a punnet square (see attached image) to produce 16 possible offsprings in a phenotypic ratio of 9:3:3:1.
9- Offsprings with both anridia and migraine
3- Offsprings with only anridia but without migraine
3- Offsprings with only migraine but without anridia
1- Offsprings without both anridia and migraine
According to the question, the chance of an offspring expressing both traits i.e. having both anridia and migraine headache is 9/16
Answer:
C
Explanation:
The anaerobic breakdown happens in absence of oxygen and produce 2 ATP, and aerobic respiration happens in presence of oxygen and produce 38 ATP.
The breakdown of molecules in the presence of oxygen is called aerobic breakdown, which produce 38 ATP of energy.
The breakdown of glucose produce two molecules of pyruvic acid.
The anaerobic breakdown of glucose is happened in absence of oxygen which convert glucose into lactate and produce 2 ATP of energy.
Thus, The anaerobic breakdown happens in absence of oxygen and produce 2 ATP, and aerobic respiration happens in presence of oxygen and produce 38 ATP.

Glucose can be broken down in two ways: aerobically (with oxygen), which is more energy-efficient and results in up to 36 ATP molecules, or anaerobically (without oxygen), which is less efficient and yields only 2 ATP molecules.
The breakdown of glucose can happen in two ways: anaerobically (without oxygen) and aerobically (with oxygen). Aerobic glucose breakdown occurs in the mitochondria of a cell and requires oxygen. This process is also known as 'cellular respiration,' and it results in a significant amount of energy (up to 36 ATP molecules from a single glucose molecule). Anaerobic glucose breakdown, also known as 'fermentation,' occurs in the cytoplasm and does not require oxygen. However, this breakdown pathway is less efficient, producing only 2 ATP molecules from a single glucose molecule.
O Mitochondrial DNA is inherited through the father.
Mitochondrial DNA can be traced for generations.
O Mitochondrial DNA requires large amounts for testing.
