A fertilized egg embeds itself on the uterine wall and as cell division occurs, it will grow from an embryo to a fetus.Answer and Explanation: There is ONE sex chromosome in an egg or a sperm. Gametes (sex cells egg or sperm) are haploid cells and contain one copy of 23 chromosomes....
Haploid describes a cell that contains a single set of chromosomes. The term haploid can also refer to the number of chromosomes in egg or sperm cells, which are also called gametes. ... the which are not haploid cells . Which of the following are haploid? Haploid cells:Gametes, egg and...
Which of them form gametes? Where does meiosis occur? Describe how the egg and sperm are produced or developed. How is genetic variation produced in meiosis? What is the name for the structure that is formed when the sperm and egg combine? What are chromosomes made up of? What are the ...
The Queen bee is the largest female, and the egg-layer of the colony. When the egg is fertilized by sperm from adrone, they develop into diploid workers (female). In contrast, unfertilized eggs develop into haploid drones (males). (Photo Credit : -kanyanat wongsa/Shutterstock) In rar...
Germ celltumors(GCTs) are a neoplasm, or an abnormal growth of cells resulting in a mass of tissue, that are derived from the germ cells, the precursors of the gametes or sex cells, namely eggs andsperm. GCTs most often arise in theovariesor testes, known collectively as the gonads, ...
There are different causes of miscarriage, but most of them are caused by faults in the genetic information of the embryo, either because one of the two gametes (egg or sperm) has some alteration, or because a genetic error occurs during the cellular multiplication of embryonic development. Doe...
Fertilization success may be severely limited in marine invertebrates that spawn both male and female gametes. In a diverse group of aquatic organisms only sperm are released, with sperm-egg fusion occurring at the mother. Here, we report fertilization kinetics data for two such 'brooding' or '...
Asexual reproduction in animals occursthrough fission, budding, fragmentation, and parthenogenesis. ... Sexual reproduction starts with the combination of a sperm and an egg in a process called fertilization. This can occur either outside the bodies or inside the female. The method of fertilization...
aFertilization in flowering plants involves two sperm cells and two female gametes, the egg cell and the central cell, progenitors of the embryo and the endosperm, respectively 受精在开花植物中介入二个精子细胞和二个女性配子,卵细胞和中央胚胎的细胞、祖先和内胚乳,分别[translate] ...
In the presence of moisture for mobility, a sperm fertilizes an egg, and the zygote (diploid cell) grows by mitosis into a new fern. Stages in Cell Division Organisms can be broadly categorized as eukaryotic or prokaryotic largely based on whether a nucleus containing DNA is present. In euka...
