Answer:
Two heterozygous parents have a <u>50%</u> chance of contributing one of their alleles to each offspring.
Explanation:
Individuals who are heterozygous for a specific trait have two different alleles in the gene that determines that trait. This characteristic makes their chances of contributing each of their alleles to the offspring 50%.
The alleles of a gene are distributed in the gametes by the process of meiosis, which results in daughter cells with half the genetic charge, so each gamete can only have one copy of the allelic pair of a gene.
On the other hand, if an individual has two equal alleles for a characteristic in a gene, he has a 100% chance of passing that allele on to his descendants.

Explanation:
Climate change affects the growth of plants in many ways but as we know its 3. The first, as CO2 levels increase, plants don't need a lot of water to do photosynthesis. Scientist have now discovered a third effect: As CO2 levels go up higher, it amps up photosynthesis. Plants in more of this heat, CO2-rich environment grow bigger and better, with more plant like leaves and such.
The reason why the interdependence of the worms and plants are example of commensalism is because of the process they show in which when the plants die, the worms dig air holes to their roots in which the worms make this in a way of having a place to live. It is because commensalism is where two organisms are being paired up in means of the other to benefit and the other to be harmed or benefit.
