Identify the causes of genetic variation as associated either with Mendel's principles or with mutation Genetic variation in successive generations can be caused either by natural occurrences , which can be explained by Mendelian genetics , or by mutation Inheritance Mutation Co- dominance Amplification VirusDeletion Incomplete Dominance
The causes of genetic variation associated with Mendel's principles are:
1. Segregation: During gamete formation, the two alleles for a gene segregate from each other, leading to different combinations in offspring.
2. Independent assortment: Genes on different chromosomes assort independently during gamete formation, leading to new combinations of alleles in offspring.
3. Crossing over: During meiosis, homologous chromosomes exchange genetic material through crossing over, leading to recombination and new gene combinations.
The causes of genetic variation associated with mutation are:
1. Spontaneous mutations: Random errors can occur during DNA replication or repair, leading to changes in the DNA sequence.
2. Mutagens: Environmental factors such as radiation or certain chemicals can induce mutations in the DNA.
3. Gene duplication: Occasionally, segments of the genome can be duplicated, leading to additional copies of genes. These duplicated genes can further mutate and diverge in sequence over time.
It is important to note that the terms "Mutation Inheritance," "Mutation Co-dominance," "Amplification Virus," "Deletion," and "Incomplete Dominance" mentioned in the question do not accurately represent the causes of genetic variation.
