C. The uneven heated of Earth's different surfaces. For e.g., land changes temperatures quicker as compared to the sea.
When the sun comes up, the land heats up quicker than the sea. As a result, air above the land will also heat up more than air above the sea. As hotter air rises from the land, the cooler air travels to the space which the hotter air rose from. This creates wind, or a cycle of air currents.
Hope this helps! :)
P.S. By the way, this seems to be more so of Geography as compared to Biology. :) No worries though!
Answer:
It is expected to observe individuals exhibiting green, yellow, blue, and white colors in a phenotypic ratio of 9:3:3:1, respectively.
Explanation:
This example is a classic case of a dihybrid cross involving two unlinked genes that differ in the same observed trait. In this case, the genotype double homozygous recessive is white, while the presence of one dominant allele in one of these genes results in individuals with either blue or yellow color. Finally, the presence of two dominant alleles results in individuals with blue color.
Phenotypic and genotypic ratios:
gene 1 two alleles U u
gene 2 two alleles N n
Cross:
UuNn x UuNn
uunn: white color (1/16)
U_nn: yellow color (3/16)
uuN_: blue color (3/16)
U_N_: green color (9/16)
