HEREDITY AND EVOLUTION
Asked by ankit95 | 22 Feb, 2010, 01:04: PM
answered-by-expert Expert Answer

Microevolution is evolution resulting from small specific genetic changes that can lead to a new subspecies. When individuals with certain traits are more successful at reproduction, the ensuing generation will have more copies of that trait. Should the trend continue, eventually the traits will become so common in the population that the population profile will change. This is microevolution.

 The main difference between microevolution and macroevolution is that one occurs within a few generations, whilst the other takes place over thousands of years.

Two human beings who can both roll their tongues produced 11 children. 3 of these children could not roll their tongues and 8 children could roll their tongues. (a) Which trait (rolling or not rolling) is controlled by the recessive allele? (b) State all possible genotypes of the F1 generation of the cross. Show the inheritance of the tongue rolling in humans in the given example using a suitable cross. What percentage of offspring will show the same genotype as the parents? OR (c) If one of the parents could not roll their tongue, with the help of a cross, calculate the ratio of tongue- rollers to non-tongue-rollers in the off springs.​
