How many chromosomes does a human gamete (egg or sperm cell) have? A) 46. B) 23. C) 2. D) 13. E) 92. In humans, each cell normally contains 23 pairs of chromosomes. How many chromosomes does a human cell contain? How many chromosomes are in a normal human cell a...
A donkey sperm contains 31 chromosomes and a horse egg 32 chromosomes, so the zygote contains a total of 63 chromosomes. The zygote develops normally. The combined set of chromosomes is not a pr Sexual reproduction requires ___. a. meiosis ...

Posterior regeneration relies on blastema formation and requires cell proliferation to proceed normally. Blastema cells express the GMP signature and likely mainly derive from a dedifferentiation process of cells next to the amputation plane [133]. Such extensive reprogramming of differentiated cells into...
(I) bind to the membrane of ovocytes and induce relocation of adhesion proteins to the surface (normally induced by sperm). Use of (I) should reduce the need for intracytoplasmic microinjection and improve the quality of embryos.WOLF, JEAN-PHILIPPE...
a single individual generally contains all of theMATgenes and is thus capable of selfing [41]. In filamentous ascomycetes the simpliest idiomorphs consist ofMAT1-1that carries one gene calledMAT1-1-1encoding a protein with an α-domain binding motif andMAT1-2that contains one gene calledMAT...
Both d and L were normally distributed, and thus analyzed with analysis of variance. Results Experiment 1: rearing host affects adult lifespan, but not inbreeding depression Rearing host affects lifespan of outbred beetles: In contrast to earlier experiments, we detected no difference Females 17 ...
They could be duplicated, paired, segregated, and inherited normally as common wheat chromosomes. The results demonstrated that wheat–rye derived line D27 was a genetically stable translocation line and a potential germplasm resource. 4.3. Multiple markers show the 1DS of D27 is replaced by 1RS...
Polyprotein genes such as Rubisco II in dinoflagellates likely have resulted from retroposition-based gene duplication, because the gene cluster contains only one regulatory system, without stop codons between individual proteins in the tandem array, characteristic of retroposed genes [104]. Polyprotein...
