The zygote is brought about as the result of sperm and egg fusion (fertilization), which occurs in the female Fallopian tube. Is a zygote a baby? The zygote develops as result of cell division, or cleavage, to form an embryo. The embryo grows in the uterus to form a fetus. The fetus...
Sequential morphological assessment of the PN is an important indicator for gamete viability, for quality of the embryo and in countries where legislation requires selection of the PN for embryo transfer. During fertilization check, the arrangement of PNs and NPBs in the best zygotes demonstrates cen...
Simply, a zygote is formed by the fusion of male gamete (sperm) and female gamete (ovum). Generally, a single sperm fuse with a single ovum, but in some cases, multiple sperms are also found to fuse with a single ovum. This process of formation of a zygote is called fertilization 1....
Answer to: Double fertilization is the formation of a and a(n). a. zygote, zygote b. zygote, pollen grain c. zygote, megaspore d. zygote, endosperm...
Double fertilization is a form of fertilization that occurs in angiosperms or flowering plants. As the name implies, double fertilization involves the fusion of two male games with the female gametophyte. Double fertilization is involved in the production of seeds....
In multicellular organisms, oocytes and sperm undergo fusion during fertilization and the resulting zygote gives rise to a new individual. The ability of zygotes to produce a fully formed individual from a single cell when placed in a supportive environment is known as totipotency. Given that toti...
Aggregation of the ribosomes begins and numerous polysomes are formed. Before division of the zygote all planktivores between the zygote and the surrounding cells are lost. The first division of the zygote is unequal as a result of its marked polarity A large basal cell and a small terminal...
(1; pp. 56–57) concluded that “66.4% of the triploids were the result of dispermy, 23.6% the result of fertilization of a haploid ovum by a diploid sperm formed by failure of the first meiotic division in the male and 10% the result of a diploid egg formed by failure of the ...
The first embryonic mitosis following fertilization in the mouse also occurs in the absence of true centrosomes and astral microtubules since the centrioles brought by the sperm are rapidly degraded20 and rebuilt de novo at the 64-cell stage21. This division is peculiar because the male and ...
Fertilization of an ovum by a spermatozoon occurs in the? A. Cervix B. Fallopian tube C. Ovary D. Uterus A zygote (fertilized egg) is formed once a: a. diploid sperm fertilizes a haploid egg cell. b. haploid sperm fertili...
