Gender or sex is determined by the male parent's sex cells. During the process of meiosis, the gametes that are produced by females (eggs) only have a... Learn more about this topic: Sex Determination, X-Inactivation, and Barr Bodies ...
Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction. Meiosis begins with a parent cell that is diploid, meaning it has two copies...
A) before mitosis and between meiosis I and meiosis II B) before mitosis, but it is not necessary for it to occur before either meiosis I or meiosis II C) before mitosis and meiosis I The period in which a cell is preparing to divide is: (A) the S phase; (B) the G_1phase (...
Ferns are mostly homosporous, though some are heterosporous. The heterosporous state is a more advanced condition, that seems to have evolved independently in several groups of plants. The haploid spores are formed by meiosis inside the sporangium. ... The spores germinate into tiny gametophytes...

formed by pitch-derived carbon; these have actually improved structural security and electric conductivity causing excellent cycling and characteristics. Tube-in-tube structured nanofibers comprising hollow CoFe2O4@GC nanospheres showed exceptional long-cycle overall performance (682 mA h g-1 when it ...
8. An oocyte is a cell which undergoes meiosis to produce an ovum or egg. 9. A catalyst is a substance that can speed up the rate of a chemical reaction without changing its own structure. 10. A black hole is a celestial body which has approximately the same mass as the sun and a...
C. albicans is an organism that may show considerable variability of certain characteristics. Genetics studies show that the organism is diploid, but apparently without the ability to undergo meiosis, yet it has impressive genetic variability between and within strains (Scherer, S. et al. 1990. ...
Phospholipase C zeta1 (Plcz1) was known to be a physiological factor in sperm that activates oocytes to complete meiosis by triggering Ca2+ oscillations after fertilisation. However, the role of male Plcz1 in spermatogenesis and early embryo development in progeny has been controversial. Plcz1 ...
