Question

(a) What is a homologous series ? Explain with an example.

(b) State two characteristics of a homologous series.

(c) The molecular formula of an organic compound is C18H36. Name its homologous series.​

Answer 1

If an organism has two copies of the same allele, for example AA or aa, it is homozygous for that trait. If the organism has one copy of two different alleles, for example Aa, it is heterozygous.

Keep in mind that an organism can't simply be 'homozygous,' period. For each of the organism's thousands of genes, it is either homozygous or heterozygous at that genetic locus.

Dominant and Recessive
Alleles can be dominant or recessive. A dominant allele takes precedence over a recessive allele. For example, the allele that gives rise to albinism is recessive, and the allele for normal pigment production is dominant. That means that a heterozygous individual with the genotype Aa, who has one copy of the normal allele and one copy of the albinism allele, would not be an albino. This is because since A is dominant, one copy of A is enough to give the normal phenotype. Make sense?

Answer 2

a) A homologous series is a series of carbon compounds that have different numbers of carbon atoms but contain the same functional group. For example, methane, ethane, propane, butane, etc. are all part of the alkane homologous series. The general formula of this series is CnH2n+2.

b) Homologous series in organic chemistry are groups of molecules that have the same basic structure, including the same functional group. They only differ in the number of methylene (CH2 ) groups. The chemical properties of homologous series are similar because they have the same functional group.
