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?
The two factors that introduce genetic variation during the process of meiosis are independent assortment and chromosomal crossover. These occur during prophase 1 and anaphase 1 of 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.
How is variation produced in each species?
Variation in species is primarily produced through genetic mutations, which are changes in the DNA sequence. These mutations can occur spontaneously or be induced by environmental factors. Additionally, sexual reproduction contributes to variation through the combination of genes from two parent organisms, leading to unique genetic combinations in offspring. Environmental influences and selective pressures also play a crucial role in shaping and maintaining variation within species.
What contributes to genetic variation?
The patterns of nitrogenous bases in DNA encoded on the genes creates genetic variation.

Does crossing over during meiosis contribute to genetic variation?
Yes, crossing over during meiosis contributes to genetic variation by exchanging genetic material between homologous chromosomes, leading to new combinations of genes in offspring.
What factors cause variation in the atmosheric elements?
genetic factors
How does crossing over during meiosis contribute to genetic variation?
Crossing over during meiosis is a process where genetic material is exchanged between homologous chromosomes. This contributes to genetic variation by creating new combinations of genes, leading to offspring with unique traits.
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?
The two factors that introduce genetic variation during the process of meiosis are independent assortment and chromosomal crossover. These occur during prophase 1 and anaphase 1 of meiosis.

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.
How does standing genetic variation contribute to the overall genetic diversity within a population?
Standing genetic variation refers to the existing genetic differences within a population. This variation contributes to genetic diversity by providing a pool of different genetic traits that can be passed on to future generations. This diversity helps populations adapt to changing environments and increases their chances of survival.
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.
