Question
If two genes are liked, they are located on the chromosome. A male who exhibits a sex-linked trait, most likely inherited it from his . The genes for sex-linked traits are carried on the . Would you expect this disease to be found equally in males and females? The diploid number for a normal human is . The two types of chromosomes in a human somatic cell are 44 and sex chromosomes. Karyotyping involves comparing chromosomes for their ,the position of the and pattern. The process that causes this abnormal number of chromosomes in the gametes is known as . During which phase of meiosis does this occur and . Give the number of autosomes, type of sex chromosomes, and total number of chromosomes in the somatic of the following:Explanation / Answer
4. Karyotyping involves comparing chromosomes for their ------length----, the position of the -------centromeres----- and ----G-band---pattern.
5. The process that causes this abnormal number of chromosomes in the gametes is known as nondisjunctioning.
During which phase of meiosis does this occur? Anaphase -I and anaphase-II.
During meiosis, the homologous chromosomes align during the prophase. These chromosomes crossover at some point and rejoin to form recombinant chromatids, and move towards the opposite poles during anaphase.
Sometimes, error occurs in meiosis during the meiosis – I or II, i.e. during the separation of homologous chromosomes. These errors result in excess or less chromosomes in the daughter cell, and this is called “nondisjunctioning.”
