What is haploid? What types of cells are diploid? What types of cells are haploid? What part(s) of mitosis is(are) haploid? A reproductive cell must differ genetically from other normal body cells in what critical way (because it will soon fuse with another reproductive cell to...
How many different kinds of gametes can be made by an individual with the genotype AaBb?Question:How many different kinds of gametes can be made by an individual with the genotype AaBb?Gametes:Gametes are sex cells, like sperm and eggs. These cells are important because t...
Because of the limited amount of data obtained from ejaculated sperm and the high interpatient variability (Martorell et al. 2000), great care must be taken in drawing conclusions from this group. The average germline change in sperm that showed an expansion was +55.9 repeats, and the highest...
Before interacting with the oolemma, spermatozoa must undergo acrosomal exocytosis, a process wherein the sperm plasma and outer acrosomal membranes fuse and the acrosomal contents are released. Following sperm–oolemma fusion, sperm nucleus decondensation occurs, the male and female haploid pronucleae...
Notably, if the reason was the absence of the first meiosis (Fig. 6B), the egg size of GDH would be close to that of the haploid eggs produced from diploid because retaining the first polar body does not markedly change the egg size, and the diameter of GDH eggs would be 0.13 ...
sperm could not fertilize the eggs because the latter are already diploid. Under conditions of environmental stress such as seasonal changes, some females form eggs that undergo reductional division, resulting in eggs with the haploid number of chromosomes; such eggs must be fertilized by a male ...
