Irregularity is found in drosophila during the organ differentiation for example-inplace of wing, long legs are formed. Which gene is responsible for:
- Double dominant gene
- Homeotic gene
- Complimentary gene
- Plastid
The Correct Option is B
Solution and Explanation
Irregularities in Drosophila during organ differentiation, such as the formation of long legs instead of wings, are controlled by Homeotic genes. These genes regulate the development of body segments and the formation of specific body parts in organisms.
So, the correct option is (B): Homeotic gene

- Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R.
Assertion A : The potential (V) at any axial point, at 2 m distance(r) from the centre of the dipole of dipole moment vector \(\vec{P}\) of magnitude, 4 × 10-6 C m, is ± 9 × 103 V.
(Take \(\frac{1}{4\pi\epsilon_0}=9\times10^9\) SI units)
Reason R : \(V=±\frac{2P}{4\pi \epsilon_0r^2}\), where r is the distance of any axial point, situated at 2 m from the centre of the dipole.

Human Genome Project
The Human Genome Project was an international research effort designed to map out the DNA sequence of an entire human genome. It was the first undertaking of its kind and took over a decade to complete. The goal of the Human Genome project was to sequence and identify the entire Human genome. And then store the entire genome information in a database. The Human Genome Project required improvement tools for data analysis.
The Human Genome Project (HGP) was an international, collaborative research program whose goal was the complete mapping and understanding of all the genes of human beings. All our genes together are known as our "genome."
Goals of the Human Genome Project
The HGP set out to establish the following goals:
- First, to identify all the approximately 20,000-25,000 genes that make up the human DNA.
- Map out the genome sequences of the 3 billion chemical base pairs that comprise the human DNA.
- Ensure the storage of the derived information in genome sequence databases.
- Optimize the tools required for the data analysis process.
- Handle the ethical, legal, and social issues (ELSI) that may arise during the project.
The shotgun phase of the Human Genome Project itself consisted of three steps:
- Obtaining a DNA clone to sequence
- Sequencing the DNA clone
- Assembling sequence data from multiple clones to determine overlap and establish a contiguous sequence
Impact of Human Genome Research
The Human Genome Project will entirely reshape the approach to all biomedical research as well as therapeutic and preventive health care. The development in fields like bioinformatics and biostatistics will allow for better pattern detection and analysis of genetic disorders.
