If genes are on different chromosomes, the law of independent assortment states that -
GaryK [48]

Answer:

Gene pairs segregate randomly and independently of each other.

Explanation:

Genes are the basic units of hereditary and are located on chromosomes. According to Gregor Mendel's law of independent assortment  which states that the alleles of two (or more) different genes are sorted into gametes independently of one another. This means that the allele a gamete receives for one gene does not influence the allele the same gamete receives for another gene.

For example, in a the pea plants used by Mendel in his studies, the genes for seed shape and flower color were inherited independent of each other by the offspring of the parent pea plants. Therefore, Mendel concluded that the inheritance of each trait was independent of the other.

At the start of a 100-yard dash (race), your body relies on which reserve as its energy source?.
Rama09 [41]

The human body reserves creatinine phosphate as the energy source at the start of 100 yard dash (race).

The creatinine phosphate is converted into ATP, which is the energy package of our body. ATP is body's usable form of energy. Energy is stored in various forms in our body such as fats, carbohydrates and proteins. At a microscopic level, it is stored in molecules like creatinine phosphate. Carbohydrate and fats are the primary source of our body followed by proteins.

Our body uses three different forms of metabolism to convert these molecules in ATPs. These three processes are Phosphagen System, Aerobic Respiration and Glycolic/Anaerobic respiration.
