An individual is heterozygous, Bb, for a gene. According to the law of segregation, each gamete formed by this individual will have either the B allele or the b allele. Which step in the process of meiosis is the physical basis for this segregation of alleles

How this helps

Question: Which step in the process of meiosis is the physical basis for this segregation of alleles?

Explanation:

The physical basis of Mendel's law of segregation is the first division of meiosis in which the homologous chromosomes with their different versions of each gene are segregated into daughter nuclei.

the answer is tropical areas. the tropical areas obtain more

radiant energy from the sun than they lose to space through terrestrial

radiation, and vice versa for polar areas. earth has an energy remaining in the

tropics and an energy scarcity for the polar areas.

explanation:

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
