Genes come in multiple forms or versions. Which of the following statements does not help explain Mendel's law of segregation? natural selection. Explained in greater detail, each gene resides at a specific locus (location on a chromosome) in two copies, one copy of the gene inherited from each parent. Nearly every living human's phenotype for the ABO gene is some combination of just these six alleles. Which one of the following can create new alleles? In addition, new alleles can be introduced in a population by gene flow, which occurs during breeding between two populations that carry unique alleles. migration.

Mutation is the ultimate source of new alleles in plant pathogen populations. Genes produce chromosomes which transmit traits from one generation to another. This may occur when the mutant allele somehow interferes with the genetic message so that even a heterozygote with one wild-type allele copy expresses the mutant phenotype. Consider eye color as an example. Does Hermione die in Harry Potter and the cursed child? Does artificial selection increase genetic variation?
