Mutation
This change is know as polyploidy.
A change in a gene could involve a mutation that alters the DNA sequence, affecting the function of the protein it codes for. A change in a chromosome could involve alterations in the structure, number, or distribution of genetic material, leading to genetic disorders or diseases.
The change in the position of a gene on a chromosome is called a mutation or a chromosomal rearrangement. This change can result in alterations to the structure or function of the gene, leading to different traits or diseases.
The condition in which a diploid cell is missing a chromosome or has an extra chromosome is called aneuploidy.
Genitic change
A mutation is the term for any permanent change in a gene or chromosome. Mutations can be caused by various factors, such as errors during DNA replication or exposure to certain environmental factors like radiation or chemicals.
The chromosome carried only by the sperm is called the Y chromosome, which determines the male gender when combined with the X chromosome from the egg during fertilization.
yes
it is called a sister chromosome :)
Mutation
In one kind of abnormal chromosome inheritance called Down syndrome, a child has three copies of Chromosome 21!
An X chromosome is known as an X chromosome based on its shape, which resembles an X. The Y chromosome resembles a Y.
