Answer:
Two heterozygous parents have a <u>50%</u> chance of contributing one of their alleles to each offspring.
Explanation:
Individuals who are heterozygous for a specific trait have two different alleles in the gene that determines that trait. This characteristic makes their chances of contributing each of their alleles to the offspring 50%.
The alleles of a gene are distributed in the gametes by the process of meiosis, which results in daughter cells with half the genetic charge, so each gamete can only have one copy of the allelic pair of a gene.
On the other hand, if an individual has two equal alleles for a characteristic in a gene, he has a 100% chance of passing that allele on to his descendants.
Answer:
Photosynthesis-process by which green plants convert carbon dioxide, water, and energy from the Sun into sugars
Ammonification- process by which certain bacteria convert organic nitrogen into ammonia and ammonium salts during decomposition
Assimilation-process by which plants or animals convert nutrients into usable organic compounds, such as proteins
Denitrification-process by which certain bacteria convert nitrates into nitrogen gas
Nitrification-process by which certain bacteria convert ammonium into nitrates
Nitrogen Fixation-process by which certain bacteria in the soil convert nitrogen gas into ammonia and ammonium
Respiration-process by which living cells produce usable energy from food
