Which processes contributes directly to genetic variation?
Mutation is the primary process that directly contributes to genetic variation by introducing new alleles into a population. Recombination during meiosis, where genetic material is shuffled and exchanged between homologous chromosomes, also plays a role in generating genetic diversity. Independent assortment during meiosis further contributes to genetic variation by producing unique combinations of maternal and paternal chromosomes in gametes.
What two factors introduce genetic variation during the process of meiosis?
Crossing over (genetic material exchange between homologous chromosomes) during prophase I and independent assortment of chromosomes during metaphase I contribute to genetic variation during meiosis.
What also contributes to genetic variation?
The two main sources of genetic variation are gene shuffling and mutations. A mutation is a process wherein the structure of a gene is altered.
Is fertilization heredity genetic variation or both?
Fertilization contributes to genetic variation by combining the genetic material from two parents to create a unique genetic makeup in offspring. The inheritance of specific genes from each parent determines the traits and characteristics of the offspring.
What are the two main factors that cause individuals of the same species to appear different?
Genetic variation and environmental factors are the two main factors that cause individuals of the same species to appear different. Genetic variation results from differences in DNA sequences passed down through generations, while environmental factors such as diet, climate, and exposure to sunlight can also influence physical appearance.
What contributes to genetic variation?
The patterns of nitrogenous bases in DNA encoded on the genes creates genetic variation.

Independent assortment during meiosis further contributes to genetic variation by producing unique combinations of maternal and paternal chromosomes in gametes.
What factors cause variation in the atmosheric elements?
genetic factors
What can the variation become?
The variation can either increase or decrease depending with the genetic factors.
What two factors introduce genetic variation during the process of meiosis?
Crossing over (genetic material exchange between homologous chromosomes) during prophase I and independent assortment of chromosomes during metaphase I contribute to genetic variation during meiosis.
What also contributes to genetic variation?
The two main sources of genetic variation are gene shuffling and mutations. A mutation is a process wherein the structure of a gene is altered.
What are the factors that contributes to the similarities and differences of organism?
Factors contributing to similarities between organisms include shared evolutionary history, genetic relatedness, and environmental pressures shaping adaptations. Differences can arise from genetic mutations, environmental influences, and unique ecological niches that organisms occupy. Additionally, variation in gene expression and epigenetic modifications can also lead to differences between closely related species.
What will make population have more genetic variation?
mutation
Is fertilization heredity genetic variation or both?
Fertilization contributes to genetic variation by combining the genetic material from two parents to create a unique genetic makeup in offspring. The inheritance of specific genes from each parent determines the traits and characteristics of the offspring.
How genetic variation and environmental factors affect evolution by natural selection?

How do genetic variation and environmental factors influence evolution?
Genetic variation drives evolution by providing the raw material for natural selection to act upon, allowing organisms to adapt to changing environments. Environmental factors can influence which traits are favored, shaping the direction of evolution. Together, genetic variation and environmental factors contribute to the diversity of life on Earth through the process of evolution.
What process is responsible for genetic variation?
The process responsible for genetic variation is genetic recombination, which occurs during meiosis when genetic material is exchanged between homologous chromosomes. Mutations, which are changes in the DNA sequence, also contribute to genetic variation.
