All the genes/alleles found in a breeding population at a given time are collectively termed as:
Correct answer: B. Gene pool
- A. Genome
- B. Gene pool
- C. Genotype
- D. Karyotype
Explanation
The correct answer is 'Gene pool' because it represents the total collection of genes, including all variations or alleles, present in a population capable of breeding. It reflects the genetic diversity within the population, which is crucial for adaptation and evolution. 'Genome' refers to the complete set of genetic material in an individual organism, not a population. 'Genotype' describes the specific genetic makeup of an individual rather than a collective group. 'Karyotype' is concerned with the chromosomal structure of an individual and is used in the context of diagnosing genetic disorders, not describing a group's genetic diversity.

About Inheritance
Mendel's laws explain segregation, independent assortment and the prediction of genetic ratios using alleles, genotypes and phenotypes. The chapter also covers linked genes, recombination and crossing over during meiosis, then applies pedigree reasoning to X-linked recessive traits, which show different inheritance patterns in males and females.
