Question

Write the specific type of chromosomal mutation:

a A portion of the end of a chromosome is missing.
b A portion of the chromosome is duplicated and position on the other arm, resulting in extra genetic material.
c Parts of different chromosomes switch places.
d Genetic material is backward.

Answer 1

The specific types of chromosomal mutations are deletion, duplication combined with translocation, translocation alone, and inversion. These mutations can have profound effects on an organism, including developmental delays in conditions like Down Syndrome.

Step-by-step explanation:

The specific types of chromosomal mutations mentioned in the question are:

• Deletion: A portion of the end of a chromosome is missing.
• Duplication and translocation: A portion of the chromosome is duplicated and positioned on the other arm, resulting in extra genetic material.
• Translocation: Parts of different chromosomes switch places.
• Inversion: Genetic material is backward.

Chromosomal mutations are significant changes to the structure of chromosomes, which can result in serious effects on an organism's development and function. Examples include developmental delays and other abnormalities due to duplications such as in Down Syndrome (trisomy 21).
