What types of chromosomes in humans determines the gender of the baby?
The sex chromosomes...XX for a female, XY for a male, with some other relatively rare variations.
How many chromosomes does a koala have?
A koala typically has 16 chromosomes. These chromosomes contain the genetic material that determines the koala's physical characteristics and functions. The number of chromosomes in a koala is relatively low compared to other mammals, such as humans, who have 46 chromosomes.
Evidence for the relatively close relationship of archaea to eukaryotes includes what?
Similarities in DNA replication machinery, RNA polymerase subunits, and the presence of introns in some archaea genomes suggest a close relationship of archaea to eukaryotes. Additionally, studies on the protein translation machinery also support this evolutionary link.
Is there a relationship between the size of an organism and the number of chromosomes?
Not necessarily. Organism size and chromosome count are not directly correlated. For example, while humans have 46 chromosomes, some plants can have hundreds of chromosomes and still be relatively small in size. The number of chromosomes can vary among different species and does not dictate the size of the organism.
Is man the highest of the animals therefore he has the most chromosomes?
No, being the "highest" of animals does not correlate with having the most chromosomes. Chromosome numbers vary widely across species, and some simpler organisms can have more chromosomes than humans. For example, the fern Ophioglossum reticulatum has one of the highest known chromosome counts, with over 1,440 chromosomes. Human beings have 46 chromosomes, which is relatively common among mammals.
What are the basic differences between prokaryic and eukaryotic?
Prokaryotes do not have a nuclear membrane or nucleoli, Eukaryotes do. Prokaryote have no organells, Eukaryote do. Prokaryotes usually have a single circular chromosome lacking histones. Eukaryotes have multiple linear chromosomes with histones. Prokaryotes replicate by binary fission, Eukaryotes by mitosis and meiosis.
How many chromosomes do fruit files have?
Fruit flies, specifically the species Drosophila melanogaster, have a total of 8 chromosomes, comprising 4 pairs. This includes three pairs of autosomes and one pair of sex chromosomes. The study of fruit flies has been pivotal in genetics and developmental biology due to their relatively simple genome and quick reproductive cycle.
Is usher syndrome a gene or chromosomal?
Usher syndrome is a relatively rare genetic disorder caused by a mutation. The gene is not carried on one of the sex chromosomes (X or Y).
Is the change in the size of the chromosomes the cause of sickle cell disease?
the sickle cell disease can be caused by many things including the change in size of chromosomes. the change of size in chromosomes can change and become either bigger or smaller. if the size doesnt change, then it doesnt get bigger or smaller which means the size stays relatively the same in general. it also makes you get a priapism
How many chromosomes does the crocodiles have?
Crocodiles typically have 32 chromosomes, arranged in 16 pairs. However, the exact number can vary slightly among different species within the crocodilian group. This chromosome count is relatively consistent across most species, reflecting their evolutionary lineage.
Do killer whales have any unusual chromosomes?
Killer whales, or orcas, have a distinctive karyotype with 2n = 38 chromosomes, which is relatively low compared to some other cetaceans. Their chromosomes exhibit unique structural features and variations that contribute to their adaptability and social behaviors. Studies of their genetics have revealed that they possess a high degree of genetic diversity within populations, which may aid in their survival in various environments. Overall, while their chromosomes are not "unusual" in a broad sense, they do have specific characteristics that reflect their evolutionary adaptations.
How many chromosomes are present in the abnormal karyotype?
In a regular human body cell, there are 46 chromosomes, 23 from each parent. Of these, 2 are sex chromosomes, so named because they determine the sex of the individual. The other 44 (22 in each set) are called autosomes. Any exceptions to the above are instances of aneuploidy. They are relatively rare.
