Answer
In this karyotype, chromosome 18 is an example of an autosome. This karyotype show the chromosome taken from a female human cell.
Normal human cell have 46 individual chromosome or 23 pairs of chromosomes.
EXPLANATION
- Other than X and Y chromosome, all chromosome are autosomal chromosome.
- The karyotype have two X chromosome thus it is of female while incase of male it would be X and Y
- Human cell have 46 in total chromosome or 23 pair of chromosomes
- 22 pair of autosome +1 pair of sex chromosome XX in female while 22 pair of autosome + X and Y sex chromosome in male

Aneuploidy of an autosome is always more harmful than an aneuploidy of a sex chromosome. One of the explanations as to why sex-chromosome aneuploids are less harmful is due to X inactivation. X-inactivation assures that all human cells only express a single X chromosome regardless of how many X chromosomes are present. Interestingly, sex chromosome aneuploids (i.e. XXY, XO) still have some different phenotypes compared to either an XX or XY individual. For instance, XXY individuals (Klinefelter Syndrome) are taller, have...

Observation: Sex Chromosome Anomalies A female with Turner syndrome (XO) has only one sex chromosome, an X chromosome; the O signifies the absence of the second sex chromosome. Because the ovaries never become functional, these females do not undergo puberty or menstruation, and their breasts do not develop. Generally, females with Turner syndrome have a short build, folds of skin on the back of the neck, difficulty recognizing various spatial patterns, and normal intelligence. With hormone supplements, they can lead...
7) Chromosome I from your mother and chromosome I from your father are said to be homologous
7) Chromosome I from your mother and chromosome I from your father are said to be homologous. This is because the chromosomes: A) appear the same size in a karyotype. B) have different genes on them. C) have the same genes on them. D) determine the sex of the child. 8) Why do karyotypes always show chromosomes at the point when cell division is about to occur? A) This is the only cell cycle point in which the chromosomes are unduplicated. B) The...

Provide a diagram of chromosomes 11 and the sex chromosomes (show the alleles associated with albinism and haemophilia) in the cells involved with normal oogenesis for this female.
