1(Of a cell or nucleus) containing two complete sets of chromosomes, one from each parent. Compare with haploid.
- An obvious question is whether the mat bias is absent in azygotic meiosis after homologous chromosomes have coexisted in diploid cells for many mitotic divisions.
- Oocytes and sperm are haploid, with one set of chromosomes, whereas somatic cells are diploid, with two chromosomal sets.
- However, to a low extent, viable spores can also be recovered from a very small population of homozygous diploid nuclei in an otherwise haploid plasmodium.
1.1(Of an organism or part) composed of diploid cells.
- Currently, six major tetraploid races are recognized and their diploid progenitors have been identified.
- Note that copy numbers in tetraploids were slightly less than double those in respective diploid progenitors.
- The compactness of rice and sorghum genomes is evident compared to barley and diploid wheat genomes.
A diploid cell, organism, or species.
- We conclude that the haploids had a greater frequency of mutant phenotypes than the diploids.
- Previous work has calculated the covariance expected under autosomal inheritance in diploids and haploids.
- In diploids, sexual reproduction promotes both the segregation of alleles at the same locus and the recombination of alleles at different loci.
- Example sentences
- Furthermore, it can be shown to hold for PGE with male somatic diploidy and for polyploid apomixis as well.
- This article generalizes their approach to allow for arbitrary modes of inheritance, including diploidy, polyploidy, sex linkage, cytoplasmic inheritance, and genomic imprinting.
- Recessive deleterious mutations are a major cause for the phenomenon of inbreeding depression, and diploidy may have evolved to mask the effects of recessive deleterious mutations.
Late 19th century: from Greek diplous 'double' + -oid.
