A given organism has actually 46 chromosomesx in its karyotype. Us can therefore conclude which of the following? 1.) it should be sexually reproducing 2.) it"s gametes must have actually 23 chromosomes 3,) it need to be primate 4.) it need to be an pet 5.) it should be a human
The somatic cell of a privet shrub every contain 46 chromosomes. To be as different as they space from human being cells, which have actually the same variety of chromosomes, i m sorry of the complying with must it is in true? 1.) gene on a details privet chromosome, such together X, have to be top top a different human chromosome, such as number 18 2.) privet shrubs should be metabolically much more like animals than like various other shrubs 3.) genes of privet chromosomes are significantly different 보다 those in human beings 4.) privet cell cannot blee sexually
In a human karyotype, chromosomes space arranged in 23 pairs. If we select one of these pairs, such together pair 14, i beg your pardon of the adhering to do the 2 chromosomes of the pair have in common? 1.) length and position of the centromere only 2.) length, centromere position, and also staining pattern only 3.) length, centromere position, staining pattern and traits coded for by their gene 4.) they have nothing in typical except they space X shaped 5.) length, centromere position, staining pattern and DNA sequences
Which is the smallest unit comprise the entire human genome? 1.) one human chromosome 2.) one person somatic cabinet 3.) the whole human populace 4.) all of the DNA of one human 5.) one human gene
For what objective (s) could a karyotype be prepared? 1.) for prenatal screening, to recognize if a fetus has the correct number of chromosomes 2.) to identify whether a fetus is male or woman 3.) to detect feasible presence of chromosomal abnormalities such as detentions, inversions, or translocations 4.) the an initial And second answers space correct 5.) an initial three answers are correct
Which of this is a karyotype? 1.) a display of a cells mitotic stages 2.) a organic cellular setup of chromosomes in the nucleus 3.) organized images of cell chromosomes 4.) the appearance of an biology 5.) a display screen of every the cell types in one organism
A triploid cell includes three sets of chromosomes. If a cell of a usually diploid types with 42 chromosomes every cell is triploid, this cell would be supposed to have actually which of the following? 1.) 63 chromosomes in 31 1/2 bag 2.) 63 chromosomes in 21 sets of 3 3.) 63 chromosomes, each with 3 chromatids 4.) 21 chromosome pairs and also 21 distinctive chromosomes
Which the the following ideal describes a karyotype? 1.) a photographic representation of every the genes for a species 2.) a photograph of all the cell with lacking or extra chromosomes 3.) the arsenal of every the chromosomes in an individual biology 4.) a display screen of every of the chromosomes that a solitary cell 5.) the combination of every the maternal and also paternal chromosomes of a species
Meiosis 1 produce ______ cells, every of i beg your pardon is ____. 1) two..... Haploid 2.) two... The same to the various other 3.) four... Haploid 4.) four... Diploid 5.) two.. Diploid
