Web21 de fev. de 2013 · Genetics is the study of how heritable traits are transmitted from parents to offspring. The theory of natural selection states that variations occur, but Charles Darwin couldn't explain how. WebIf the assumptions are not met for a gene, the population may evolve for that gene (the gene's allele frequencies may change). Mechanisms of evolution correspond to violations of different Hardy-Weinberg assumptions. They are: mutation, non-random mating, gene flow, finite population size (genetic drift), and natural selection.

WebShruthi. a hybrid means that the offspring is heterozygous. in regular mendelian genetics, its genotype would be a dominant allele and a recessive allele (ex. Aa). in incomplete dominance and codominance (non-mendelian genetics), it would mean that it has two different alleles (ex. AB or A^1 B^1). Web10 de fev. de 2012 · New alleles arise through mutations (e.g., point mutations, like when the base or nucleotide A is changed to C, G, or T) and recombination of existing alleles.
