Question

List and briefly describe the three processes that lead to variation in offspring from the same parents.

a) Mutation, genetic drift, natural selection
b) Recombination, independent assortment, fertilization
c) Adaptation, meiosis, migration
d) Cloning, gene flow, speciation

Answer 1

The three processes that lead to variation in offspring from the same parents are genetic recombination, fertilization, and meiosis.

Step-by-step explanation:

The three processes that lead to variation in offspring from the same parents are genetic recombination, fertilization, and meiosis. Genetic recombination occurs during meiosis and leads to the shuffling and recombination of genetic material from the parents, creating new combinations of genes in the offspring. Fertilization is the fusion of the egg and sperm, which brings together the genetic material from both parents. Meiosis is the process by which the cells that give rise to the egg and sperm undergo division, resulting in the production of haploid cells with unique combinations of genes.
