Gamete Ahaploid cellthat undergoes fusion to produce azygotein the context of sexual reproduction. Gametophyte The haploid multicellular stage of the land plant lifecycle. When the spores are not equivalent, with some spores giving rise tomale gametophytesand others, to female gametophytes. ...
Maternal gametes always contain an X chromosome, so the sex of the animals’ offspring depends on whether a sex chromosome is present in the male gamete. 有時字母0表示缺少第二個X.母性配子總是包含X染色體,因此動物後代的性別取決於雄性配子中是否存在性染色體。 LASER-wikipedia2 Structure and ...
To evaluate genome-wide signatures of natural selection on loci associated with gamete numbers, we first performed GWAS for pollen and ovule numbers using a genome-wide single-nucleotide polymorphism (SNP) data set for these lines, which was obtained by imputation based on genome-wide resequencing ...

While a seif-fertilising plant makes equal male and female gamete contributions to the next generation, so that male gamete contributions can be extrapolated from data on functional embryo sacs, this situation need not hold in outcrossing plants. Here the 1 1 ratio between male and female ...
Male definition: Of or denoting the gamete that is smaller and more motile than the other corresponding gamete. Used of anisogamous organisms.
To solve the question regarding where the largest ovules, male and female gametes, and plants are found, we can break it down into the following steps:Step 1: Identify the largest ovules - The largest ovules are found in <stron
The gametophyte is a stage in the plants life cycle that undergoes alternation of generations.The primary job of gametophyte is Gamete production.
