Gymnosperm, any vascular plant that reproduces by means of an exposed seed, or ovule—unlike angiosperms, or flowering plants, whose seeds are enclosed by mature ovaries, or fruits. The seeds of many gymnosperms (literally “naked seeds”) are borne in cones and are not visible until maturity.

Answer:
The water molecule has a slight negative charge near its oxygen atom and a slight positive charge near its hydrogen atoms, but when a neutral molecule has a positive area at one end, and a negative area at the other, it's called a polar molecule.

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)
