WebIn maternal haploids, the genomes originate exclusively from the seed parent plant. Haploid induction in this case is caused by the pollinator parent. The opposite applies to the induction of paternal haploids, where the pollinator serves as genome donor and the female as the inducer (Kermicle, 1969). Paternal haploids Web26 apr. 2024 · Haploid cells contain half the number of chromosomes as diploid cells. A human diploid cell contains a total of 46 chromosomes ( 2n = 46 ), so a haploid cell will contain 23 chromosomes ( n = 23 ).
