Can someone please explain the concept of Inversions. Or at least the difference between a inversion on a homozygote vs heterozygote.

Thanks!

This is a chromosomal mutation. Chromosomal inversion is when large parts of DNA are switched so the sequences are switched. Chromosomal translocation is when parts of chromosomes are moved to other parts of the genome (to other parts of different chromosomes). Chromosomal inversion can be seen among the DNA of fruit flies. Some combinations (resulting from inversion) are better in different types of weather. Polyploidy is when whole sets of chromosomes are added to an individual’s genome.
