Species I has 2 n = 8 chromosomes and species II has 2 n = 14 chromosomes. What would the expected chromosome numbers be in individuals with the following chromosome mutations? Give all possible answers. Q. Autotetraploidy in species II
Species I has 2 n = 8 chromosomes and species II has 2 n = 14 chromosomes. What would the expected chromosome numbers be in individuals with the following chromosome mutations? Give all possible answers.
Q. Autotetraploidy in species II
Any event that marks the change in the number of chromosomes is known as chromosome abnormality or chromosome mutation. It mainly includes deletion and insertion. A full set of chromosomes is known as a karyotype. This results due to the errors that occur during cell division.
It is given that 2n= 8. All of the possible condition of chromosome mutation and the number of chromosomes associated are mentioned below:
(a) Monosomy- The number of chromosomes will be 7.
(b) Autotriploid- The number of chromosomes will be 12.
(c)Autotetrapolid - The number of chromosomes will be 16.
(d) Trisomy- The number of chromosomes will be 9.
(e) Double monosomy- The number of chromosomes will b e6.
(f)Nullisomy- The number of chromosomes will be 6.
(g) Autopentaploid- The number of chromosomes will be 20.
(h) Tetrasomic- The number of chromosomes will be 10.
