Answer:
1. 50% of the genome comes from each parent because it is crucial otherwise if the ratio changes, the zygote may not form and if formed the fetus may have some other kind of chromosome number related syndromes etc.
2. Sexual reproduction produces greater genetic variability than asexual methods. This is because of the process of crossing over during meiosis that exchange the segments of chromosome that is necessary for producing mutations and genetic variability.
3. 50% of chromosomes match with each parent because both of the parents contributed 23 chromosomes and exactly 50% of their genome.
4. The gametes must be produced by two different individuals cause that is the main purpose of sexual reproduction and give better survival like this to the forming next generation. Not to mention produces greater genetic variability among species.
5. Plants always produces both eggs because they are hermaphroditic in nature.
Hydrophonic plants are plants that is living in the lands,
and obviously the aquatic plants that are typically used to style aquariums.
However, the bubbles you can perceive in an aquatic plant can perhaps be a source
of oxygen which is recognized as one of the products of plants as well as human respiration. The bubbles
are oxygen and are created from the thylakoid membrane in the chloroplast over photosynthesis.
