Answer:
genes, alleles, dominant, sexually reproducing, two copies, segregate, gametes, independently
Explanation:
The inheritance of biological characteristics is determined by individual units called *genes*, which are passed from parents to offspring. Where two or more *alleles* of the gene for a single trait exist, some alleles may be *dominant* and others may be recessive. In most *sexually reproducing* organisms, each adult has *two copies* of each gene. These genes *segregate* from each other when *gametes* are formed. Alleles for different genes usually segregate *independently* of each other.
Answer:
These reactions are also called the light-independent reactions because they are not directly driven by light. ... Unlike the light reactions, which take place in the thylakoid membrane, the reactions of the Calvin cycle take place in the stroma (the inner space of chloroplasts).
