| Our ability to detect doubly recombinant chromosomes depends on the genotype of the homolog after fertilization. |
| The onset of hyperactive movement occurs near the site of fertilization and is crucial for penetrating the egg's zona pellucida. |
| This relationship required water for fertilization, so this group grew close to the ground, often preserving the thallophytic structure. |
| During copulation, the female transfers unfertilized eggs to the male's ventral surface, where fertilization takes place. |
| Such a mutant megagamete could participate in fertilization with wild type pollens and sometimes set aberrant seeds with twin embryos. |
| During pollination the female portion of the plant receives pollen from the tassel, resulting in fertilization of the ovule. |
