Haploid in a sentence

During double fertilisation in angiosperms the haploid male gamete combines with two haploid polar nuclei to form a triploid primary endosperm nucleus by the process of vegetative fertilisation.

In many organisms, the haploid stage has been reduced to just gametes specialized to recombine and form a new diploid organism; in others, the gametes are capable of undergoing cell division to produce multicellular haploid organisms.

It is a haploid multicellular organism that develops from a haploid spore that has one set of chromosomes.

The cycle of haploid reproduction, with occasional fusion to a transient diploid state, followed by splitting to the haploid state, can be considered to be the sexual cycle in its most primitive form.

The diploid stage is relatively short compared with that of haploid stage, i.e. haploid dominance.

The haploid organism's gamete then combines with another haploid organism's gamete, creating the zygote.

The number of chromosomes in a single set is called the haploid number, given the symbol n. Gametes ( sperm and ova ) are haploid cells.

All plants and many fungi and algae switch between a haploid and a diploid state, with one of the stages emphasized over the other.

Although they do not use the haploid/diploid method of sexual reproduction, bacteria have many methods of acquiring new genetic information.

Animals hatnote Hoverflies mating Most sexually reproducing animals spend their lives as diploid organisms, with the haploid stage reduced to single cell gametes.

A protocell that was haploid (one copy of each RNA gene) would be vulnerable to damage, since a single lesion in any RNA segment would be potentially lethal to the protocell (e.g. by blocking replication or inhibiting the function of an essential gene).

As an example, the chromosomes of common wheat are believed to be derived from three different ancestral species, each of which had 7 chromosomes in its haploid gametes.

Asexual, non-motile haploid spore of a fungus, which is named after the Greek word for dust; conia and hence also known as conidiospores and mitospores.

Because the ploidy is reduced from diploid to haploid, meiosis I is referred to as a reductional division.

Bryophyte still maintains the sexual reproduction during its evolution despite the fact that the haploid stage does not benefit from heterosis at all.

Community interactions Coccolithophorids are predominantly found as single, free-floating haploid or diploid cells.

Cycling meiosis and fertilization events produces a series of transitions back and forth between alternating haploid and diploid states.

During gametogenesis —the production of new gametes by an adult—the normal complement of 46 chromosomes needs to be halved to 23 to ensure that the resulting haploid gamete can join with another gamete to produce a diploid organism.

During sexual reproduction there is a diploid phase, which commonly is very short, and meiosis restores the haploid state.

Each one of the four haploid nuclei migrates into its own basidiospore.
