Exempel på haploid

• As such it was done without chromosomal replication : two haploids recombined their genomes and then separated as haploids again.

• Inability of mature oocytes to create functional haploid genomes from somatic cell nuclei.

• A subset of clones was verified more thoroughly by measuring under r40 magnification the sizes of the haploid colonies obtained after tetrad dissection.

• The primary spermatocytes divide meiotically to generate the secondary spermatocytes and haploid spermatids in successive divisions.

• It is considered that the mitochondria are maternally inherited and are, therefore, haploid (clonal).

• A detailed linkage map of rainbow trout produced using doubled haploids.

• Experiment 2 compared cell number and incidence of apoptosis in diploid and haploid parthenotes.

• If selection occurs during the haploid phase, haploid selfing leads to the same population-level consequences as haploid apomixis.

• This is done below and it is found that the kind of epistasis also strongly influences the (haploid) error threshold.

• The same will be true if the ratchet has advanced sufficiently far that a substantial proportion of loci are fixed within haploid sets.

• This might be expected when haploids are compared with heterozygotes, but not necessarily expected when haploids are compared with homozygous mutant diploids.

• In this experiment, the aim was to measure growth rate of diploids in conditions as similar as possible to that used for haploids.

• Let us now consider an infinite population of haploids, or diploids without dominance, which experience mutation and selection, but no recombination.

• In our study, chromosome gain was only apparent in the haploid strains.

• In order to test for ' dominance ', crosses were made between haploids derived from a single heterozygous mutant strain.
