If you wanted to be certain that a trait would appear in the offspring of the plants or animals that you were breeding, what wou
katrin2010 [14]
What genes each parent had for that trait. 

Example: In peas, the trait for green peas is dominant (G) and the trait for yellow peas (g) is recessive. If you want the offspring to definitely be yellow, then both parents have to be yellow, with the allele frequency of gg. If both parents were carriers of the yellow gene, but were green (Gg), then there is a 25% chance of having yellow offspring, the rest being green. If one parent is a carrier (Gg) and the other is yellow (gg), then there is a 50% chance of having either yellow or green offspring. If one parent is homozygous (two alleles of the same gene) dominant, then no matter who that parent is paired with, then the offspring will definitely be green.

Explanation:

The plants can reproduce by the means of asexual reproduction and sexual reproduction. The pollen grains and egg cell fertilize with each other in the sexual reproduction.

The seedless vascular plants and non vascular plants required the means of dispersal for their fertilization. Their egg cell fuses with the pollen grains that are dispersed by animals or wind. Water is not required for the fertilization of the vascular plants.

What goes in and out of a cell respiration?
Scorpion4ik [409]

The chemical equation of cellular respiration is C6H12O6 + 6 O2 + 6 H20 -------> 6 C02 + 12 H20. Meaning glucose, oxygen, and water go into the process with carbon dioxide and water being produced by cellular respiration.
