Answer: Meiosis is the necessary process for the inherited traits of an organism to be passed along by sexual reproduction to bring about variation.
Explanation: Meiosis occurs in reproductive cells. It halves the chromosome number of parents to produce same (constant) number of chromosomes in the offsprings.
Meiosis leads to genetic variation among offsprings through recombination, crossing over, independent assortment and reduction and fusion of gametes.
Most abnormalities that are heritable are as a result of improper division during meiosis.
Answer:
Derived trait
Explanation:
An ancestral (or primitive) trait/character is a feature inherited from the common ancestor of the species/group of interest, while derived traits are those that were absent in the last common ancestor of the group of interest. For example, considering mammals as the target group, the presence of hair is a shared derived trait relative to other vertebrates, i.e., amphibians, reptiles, and birds. However, this trait (hair) is ancestral for humans since the genetically closest species to humans (e.g., chimpanzees) also have hair.
