Plants such as epiphytes or orchids have aerial roots. Epiphyte plants grow on other plants without harming them. Aerial roots of orchids are needed for physical support: to climb other plants and compete for sunlight.

Orchids are epiphytic plants which means they grow on other plants and trees. To grow on other plants, they exhibit small tentacles like structures called aerial roots.

Aerial roots grow above the soil towards the sky. In orchid plants, these aerial roosts help them to grow and attach to other plants. It is a normal behavior seen in orchids.

Moreover, their ability to grow on other plats does not harm the host plants as orchids get their food from the surrounding environment which contains necessary nutrients.

Assuming that both parents are heterozygous for the gene that causes the disease, what is the probability that the second child
LiRa [457]
The independent assortment of genes is a principle of Mendel and of genetics. Since humans are diploid organisms (they have 2 copies of their genetic information), we have that each gamete carries one of the two available alleles for each feature. These gametes are created in equal proportions.

We have that both parents are heterozygous for a feature, lets say H. Thus, their genotype is Hh. Hence, the child will get with probability 50%=1/2 H from the father and 50%=1/2 h from the father; same from the mother. By doing a Punnett square, we get that there is 1/4 chance that the child is HH, 1/2 chance that it is Hh and 1/4 that is hh. Since the disease is recessive (so both alleles are needed), we have that the chance that the kid has the disease is 1/4.
