Question

what are the symptoms of homologous series?(2marks)​

Answer 1

Answer:

Homologous chromosomes are chromosome pairs (one from each parent) that are similar in length, gene position, and centromere location. The position of the genes on each homologous chromosome is the same, however, the genes may contain different alleles. Chromosomes are important molecules as they contain DNA and the genetic instructions for the direction of all cell activity. They also carry genes that determine individual traits.

Answer 2

Features include a general formula and neighbouring members differing by CH2, with similar chemical properties and with a gradation in physical properties. Homologous series are 'families' of organic compounds. They share common characteristics: They all contain the same functional group.
