Assuming a typical monohybrid cross in which one allele is completely dominant to the other, what phenotypic ratio is expected i

f the F1's are crossed?
Biology
1 answer:
IgorC [24]4 years ago
8 0

Answer:

Assuming the dominant allele is represented as A, and the genotype as AA and the recessive as a, and genotype as aa; then the F1 will produce the offispring. Aa, Aa, Aa,Aa in ratio: 1:1:1:1:1

This shows the dominance of allele A.

However if two of  the F1 generation are crossed then:

The  F2 is AA,Aa,Aa,aa the phenotypic ratio is

                        3   ;     1

W<u>hile the Genotypic ratio is ratio;</u>

<u>   1AA : 2Aa Aa; 1aa(1 ;2;1)</u>

Why does diversity increase as height above land increases​
wolverine [178]

Biodiversity rises with altitude initially before falling with height beyond that. Up until it reaches a diversity peak at about 1 300 to 1 800 m.

  • The biodiversity increases at higher geographical locations because There are more hiding locations. They are better for crop growth. They frequently include more than one kind of habitat.
  • As latitude or altitude change, so does biodiversity. As we descend from high to low elevations, the diversity increases (i.e., from poles to equator).
  • While the environment is harsh and plants have a brief growing season in the temperate region, tropical rain forests provide year-round growth-friendly circumstances.
  • This enables the emergence and expansion of several species. On a mountain, there is an initial increase in species diversity after which there is a decline in species variety as you go up in elevation.
  • At higher elevations, temperature drops and seasonal variations increase, which significantly diminishes.
