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.
Answer:
well in my view science is a technology without it we hadn't be sucess
Plasticity is most adaptive when the environment change <u>Slowly and predictably </u>throughout an organism's life.
The ability of individual genotypes to create various phenotypes when exposed to various environmental situations is known as phenotypic plasticity. Here, the emphasis is on the role of plasticity in evolution rather than the evolution of plasticity itself, i.e., the evolution of phenotypic traits and organismal variety through plasticity. Phenotypic plasticity is a crucial characteristic of developmental systems that enables the organism to deal with environmental variability and/or unpredictability, although its significance for adaptive evolution is still debated.
