In humans, the typical male has a diploid karyotype of 46 chromosomes i.e. 22 pairs of autosomes and XY pair of gonosomes(46,XY).A standard female karyotype is 46 XX.Thus humans are dimorphic: there is one type of humans who are males and the other type is female. The basis of ...
Homologous chromosomes are complementary chromosomes that have the same genes. However, each homologous chromosome has different versions of the genes called alleles. Diploid organisms have two copies of each homologous chromosome in their nucleus.
What are the differences between sexual and asexual reproduction? Briefly describe the differences between mitosis and meiosis. Explain how mitosis results in two genetically identical diploid cells and meiosis results in four genetically no...
The two chromosomes are not seperated during Meiosis I. The cells are diploid, therefore in order to distribute the chromosomes eqully among the daughter cells so that they contain half the chromosome , Meiosis II is necessary ...
For persons who have never been vaccinated against rabies, postexposure antirabies vaccination should always include administration of both passive antibody (HRIG) and vaccine (human diploid cell vaccine [HDCV] or purified chick embryo cell vaccine [PCECV]). Persons who have ...
Strongyloides papillosus, a clade IV nematode, reveals that ND is haploid (Fig.3), and may have fused to a sizable portion of Nigon-B (NB) (Fig.3). These results are consistent with prior results showing chromosomal diminution due to a fusion between an autosome (NB) and a chromosome ...
Polyploidy plants are often vigorous, bearing larger fruit, and they grow faster than their diploid counterparts. Predict how this affects the artificial selection of crops. 9. The Cavendish banana ,or table banana, is a hybrid of Musa acuminata and Musa balbisiana. It is unable to sexu...
functional capacity. Cells grown in culture from older donors have a reduced capacity to divide and function when compared to cells grown from younger donors. Before cells die in culture they reveal several hundred changes, many of which are similar to those changes that occur in the intact ...
To solve the question regarding the number of chromosomes in the meiocyte of onion, potato, housefly, humans, and Ophioglossum, we will follow these steps:1. Understanding Meiocytes: Meiocytes are diploid cells (2n) that underg
What is the difference between cell division - mitosis and meiosis? What are the individual DNA molecules in a cell called, which become visible as tightly coiled bundles during mitosis and meiosis? What type of cell division starts with a diploid cell and ends up with a haploid cel...
