Biology – Genetics Verified Guide

- Answer: An allele is a specific version of a gene. Each trait is influenced by two alleles.
2. What does it mean for a trait to be recessive?
- Answer: A recessive trait only manifests in the phenotype when an organism inherits two copies of
the recessive allele, as it is masked by a dominant allele.
3. What is a gamete?
- Answer: A gamete is a sex cell, which can be either sperm in males or an egg (ovum) in females.
4. What role does adenine play in genetics?
- Answer: Adenine is one of the four bases found in DNA and specifically pairs with thymine.
5. What are amino acids?
- Answer: Amino acids are the fundamental building blocks of proteins.
6. How is asexual reproduction defined?
- Answer: Asexual reproduction is a process where a single parent produces genetically identical
offspring without the involvement of gametes.
7. What are autosomes?
- Answer: Autosomes are chromosomes that are not involved in determining the sex of an organism.
8. What is a base in the context of DNA?
- Answer: A base is one of four chemical components that constitute the 'rungs' of the DNA ladder:
adenine (A), thymine (T), cytosine (C), and guanine (G).
, 9. What is a base pair?
- Answer: A base pair consists of two bonded bases that make up each rung of the DNA: either A with T
or C with G.
10. What does biodiversity refer to?
- Answer: Biodiversity represents the variety of species present within an ecosystem.
11. What is the definition of a cell?
- Answer: A cell is the basic structural and functional unit of all living organisms.
12. What does cell division involve?
- Answer: Cell division is the process by which a single cell divides to form two or more daughter cells.
13. What are chromosomes?
- Answer: Chromosomes are thread-like structures that carry genes and are located in the nucleus of a
cell.
14. How would you define a characteristic?
- Answer: A characteristic is an inherited feature that distinguishes one organism from another.
15. What is cloning?
- Answer: Cloning is a technique that creates genetically identical individuals.
16. What is cytosine's role in DNA?
- Answer: Cytosine is one of the bases in DNA that pairs specifically with guanine.
17. What is DNA?
- Answer: DNA, or deoxyribonucleic acid, is a molecule located in the nucleus of cells that encodes an
individual's genetic information.
