normally, crossing over occurs between homologous regions of homologous chromosomes. sometimes mistakes happen, and crossing over occurs between non homologous regions of homologous chromosomes, resulting in duplications and deletions. what characteristic of a chromosome would make non homologous recombination more likely?

Respuesta :

The characteristic of a chromosome would make non homologous recombination more likely to be nonhomologous regions of homologous chromosomes.

Biology uses the term "single nucleotide polymorphism" (SNP) to describe a single base pair variation that is prevalent in the population. A mutation is defined as any change in the DNA sequence. In more detail, a polymorphism is any genomic region where at least two distinct sequences are discovered, with each sequence present in at least 1% of the population. The word "polymorphism" is frequently used to describe a normal variation or one that doesn't directly cause sickness. Additionally, the threshold of at least 1% prevalence for a variation to be categorized as a polymorphism is somewhat arbitrary; if the frequency is lower than this, the allele is often recognized as a mutation.
