Question

'Gene-mapping' technology was developed by

• A. Mendel
• B. Tschermak
• C. Correns
• D. Strutvent

Answer 1

The Correct Option is D

Step 1: Understanding Gene-Mapping Technology
Gene mapping involves determining the location of genes on a chromosome and understanding their relative distances. It was an important breakthrough in the field of genetics as it allowed researchers to understand how traits are inherited.

Step 2: Key Contributors to Gene Mapping

• Mendel: Known for his foundational work in genetics, Mendel laid the groundwork for inheritance studies but did not develop gene mapping technology.
• Tschermak: A contemporary of Mendel, who also contributed to genetics but did not directly develop gene mapping technology.
• Correns: Another geneticist who worked on inheritance patterns, but gene mapping was not his direct contribution.
• Sturtevant: Sturtevant was the scientist who first developed gene mapping technology. He used recombination frequency to map genes on chromosomes in the early 20th century.

The correct answer is (D) : Strutvent.

Answer 2

The correct answer is: (D) Strutvent.

Gene-mapping is a technology used to determine the location and sequence of genes on chromosomes. This technology has been crucial in the study of genetics and is used to understand genetic diseases, traits, and inheritance patterns.

The technology for gene mapping was first developed by Strutvent, who made significant contributions to the understanding of the genetic code and gene organization. This development has enabled the identification of specific genes associated with various traits and diseases in humans and other organisms.

Thus, the correct answer is (D) Strutvent, who developed the technology behind gene mapping.
