What is double hapoid?

Double haploid refers to a type of organism or cell that contains two identical sets of chromosomes. This is achieved through a process called haploid induction, where the organism or cell is forced to undergo a doubling of its chromosomes. This results in a homozygous state, meaning that both sets of chromosomes are identical. Double haploids are commonly used in plant breeding and genetic research as they allow for the rapid development of purebred lines.
