If a hypothesis is supported it becomes a theory if its not he or she has to make another hypothesis
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.
Which is one of the six fundamental elements that are found in living organisms?
Plants have a cell wall and chloroplasts; animal cells do not have either
Hope this helps : )
SELECTIVE BREEDING INVOLVES CHOOSING PARENTS WITH PATICULAR CHARACTERISTICS TO BREED TOGETHER AND PRODUCE OFFSPRING WITH MORE DESIRABLE CHARACTERS . ... CROSS BREEDING INVOLVES TWO DIFFERENT BREEDS FROM THE SAME SPECIES TO CREATE A NEW BREED
