Guarantying is a useful tool used in evaluating genetic problems such as chromosomal alternations. The test identifies and examines chromosomes in a sample of cells, by isolating them from an individual. In culture, cells divide asynchronously. Cell division of these cells is halted in metaphors because they provide the best image for analysis. Chemical stains are also used to make the chromosomes visible and ready to be examined, compared, and paired. Hypothesis & Prediction Here I analyze the identification of an unknown individual species.

The unidentified individual was one of seven possible mammal species: gorilla, human, Geoffrey spider monkey, beluga whale, okapi, aardvark, or red kangaroo. If the organism’s sex chromosomes and diploid and haploid numbers are equivalent between the unknown and known species then the individual will match the reference for that species. Methods Here I test the identity of a species of an anonymous individual with the use of a eukaryote. Was given the eukaryote number 4. The instructor provided a copy of a mitotic chromosome spread of one of the unknown individuals.

I examined he chromosomes and identified distinct ones displayed. I cut each chromosome out with scissors. I arranged the chromosomes in pairs based on size and morphologies. I determined and recorded the diploid number, haploid number, and the sex of the individual. I reviewed the reference provided and compared each known species with my eukaryote. Determined the species and sex of the unknown individual based upon the numbers of chromosomes present. The instructor approved my arrangement and confirmed my answer. I recorded my discovered species on my data sheet.

I then taped the chromosome pairs on the ATA sheet according to my previously accepted layout. I separately taped the sex chromosome pair in the lower left hand corner of the data sheet. Results was assigned the eukaryote number 4. Based upon my chromosome sex chromosomes and haploid and diploid numbers I was able to distinguish the unknown individual species as a female gorilla. During arrangement, the chromosomes were especially distinguished by observing physical features such as size, banding pattern, and controvert position.

I referred to the reference and was correct with essentially an exact eukaryote match. The diploid number of my species was 46 and the haploid number was 23. The individual was a female with XX sex chromosomes. Discussion The importance of eukaryotic and guarantying is the ability to identify the sex of a particular organism and detect chromosomal conditions such as rearrangements, missing, or extra parts of chromosomes. It is important to observe the lengths, controvert position, banding pattern, and differences between the sex chromosomes and outcomes.

Controvert positions pertain to meteoritic, sub-meteoritic, telekinetic positions. Each normal eukaryote includes a certain amount of chromosomes as well pairs, and one pair of sex chromosomes. For a male, the sex chromosomes are XX and for a female, the sex chromosomes are XX. Although I did not have any issues identifying my unknown species, some methodological errors that could have occurred include receiving a bad mitotic chromosome spread, mismatching chromosome pairs, manipulated, or having a missing chromosome It is easy to mismatch chromosome pairs when there are several different chromosomes present.

I could have paired chromosomes that were not exact to the reference, but they were accurate enough to make an appropriate prediction. My pairs were arranged as well as possible. Missing a single chromosome indicates your species is of the male sex because of the XX. Biological errors that could have occurred during guarantying, deal with chromosome numbers and shapes which include the alteration of manipulated, a situation where chromosomes numbers are not equivalent to the typical number of that species. This condition causes an extra or lost chromosome, a common effect of introductions during meiosis in the formation of a gamete.
