Genes and Alleles: Units of Inheritance — NEET Biology
📚 Practice ConceptBased on these observations, Mendel proposed that something was being stably passed down, unchanged, from parent to offspring through the gametes, over successive generations. He called these things as 'factors'. Now we call them as genes. Genes, therefore, are the units of inheritance. They contain the information that is required to express a particular trait in an organism. Genes which code for a pair of contrasting traits are known as alleles, i.e., they are slightly different forms of the same gene.
Match the Column I (Term) with Column II (Description/Definition). Column I (Term) a. Allele b. Monohybrid c. Phenotype d. Homozygous e. Genotype Column II (Description/Definition) i. Observable expression of a trait ii. Having identical alleles for a trait iii. Different forms of a gene iv. Genetic constitution of an organism v. Heterozygote for a single gene
