Exempel på hur man kan använda HAPLOID i en mening

• It is a haploid multicellular organism that develops from a haploid spore that has one set of chromosomes.
• It involves two rounds of division that ultimately result in four cells, each with only one copy of each chromosome (haploid).
• A spermatozoon is a moving form of the haploid cell that is the male gamete that joins with an ovum to form a zygote.
• The sexual fusion of haploid cells is called karyogamy, the result of which is the formation of a diploid cell called the zygote or zygospore.
• In eukaryotes, there are two distinct types of cell division: a vegetative division (mitosis), producing daughter cells genetically identical to the parent cell, and a cell division that produces haploid gametes for sexual reproduction (meiosis), reducing the number of chromosomes from two of each type in the diploid parent cell to one of each type in the daughter cells.
• Sporangia can produce spores by mitosis, but in land plants and many fungi, sporangia produce genetically distinct haploid spores by meiosis.
• In plants both phases are multicellular: the haploid sexual phase – the gametophyte – alternates with a diploid asexual phase – the sporophyte.
• Like liverworts and hornworts, the haploid gametophyte generation of mosses is the dominant phase of the life cycle.
• These somatic cells are diploid, containing two copies of each chromosome, whereas germ cells are haploid, as they only contain one copy of each chromosome (in preparation for fertilisation).
• Gametogenesis is a biological process by which diploid or haploid precursor cells undergo cell division and differentiation to form mature haploid gametes.
• haplontic life cycle — the haploid stage is multicellular and the diploid stage is a single cell, meiosis is "zygotic".
• The sporophyte develops from the zygote produced when a haploid egg cell is fertilized by a haploid sperm and each sporophyte cell therefore has a double set of chromosomes, one set from each parent.
• In all bryophytes, the primary plants are the haploid gametophytes, with the only diploid portion being the attached sporophyte, consisting of a stalk and sporangium.
• The primary spermatocyte divides meiotically (Meiosis I) into two secondary spermatocytes; each secondary spermatocyte divides into two equal haploid spermatids by Meiosis II.
• It consists of three parts: the integument, forming its outer layer, the nucellus (or remnant of the megasporangium), and the female gametophyte (formed from a haploid megaspore) in its center.
• The gonialblast undergoes mitotic transit-amplifying divisions to produce spermatocytes which will eventually give rise to haploid spermatids.
• An antheridium is a haploid structure or organ producing and containing male gametes (called antherozoids or sperm).
• This diploid cell, called a zygote or zygospore can then enter meiosis (a process of chromosome duplication, recombination, and division, to produce four new haploid cells), or continue to divide by mitosis.
• When the microspores undergo meiosis in the spring, four haploid microspores are produced which eventually become pollen grains.
• A haplotype (haploid genotype) is a group of alleles in an organism that are inherited together from a single parent.
