Question

What alleles do the F1 offspring have? Explain which allele was inherited from each parent.

Answer 1

Allele is defined as the alternate form of a gene. The alleles of the F1 off springs of the Mendel's work are dominant alleles. Dominant allele is the main allele. For any genetic trait everyone possess two alleles where as in reproductive traits such as egg, sperm only one allele is present for any trait. Parents generally contribute one allele per one gene.The allele inherited from each parent may be recessive or dominant. This is because each individual parent possess both the alleles that is dominant or recessive hence the offspring may possess half of the characteristics of the alleles from both the parents. Therefore the alleles which are inherited from parents may be either dominant or recessive. Mendel took the lines of pure breeding peas of green and yellow and self fertilised, then these plants produced off springs of with the same trait. The pea pods on one plant will produce green colour pods where as the pea pods on the other plant will produce yellow colour pods this is defined as the F1 generation.
