Incomplete dominance is when hybrids of the F1 generation have an intermediate phenotype (between the two phenotypes). That is, in the case of familial hypercholesterolemia, if the subject is heterozygous it will have 50% functional receptors compared to a healthy homozygous subject.

Lawn and farming fertilizer is harmful to the enviroment due to the abundance of chemicals. When it rain or seeped underground, the fertilizer leaked into the nearby lake and thus, all the fish died to the chemicals in the fertilizer.
It is true that the gametophytes grow directly from the sporophyte
Answer: Option C
<u>Explanation:</u>
Conifers are distinct by the presence of evergreen needle shaped leaves and seeds that are generally attached to the cone. The conifers are generally pines which grow into tall trees and bonsai varieties are the smallest. They do not produce seeds in the fruits like other trees rather store it in a thick woody cone where it can be protected during forest fires.
In conifers the process from pollination to fertilization takes about a year. The plant in which the gametophyte grows is called as the sporophyte. This sporophyte is where the male and female gametes fuse together to form the first cells the zygote. Then this zygote develops into a seed. This seed is then disbursed through wind and end up forming a new baby plant called the sporophyte.
