Question

what is allele or allelomorph? and what will be the ratio of offspring when heterozygous tall cross with each other in f2 generation? ​

Answer 1

Answer:

An allele is a variant form of a given gene, meaning it is one of two or more versions of a known mutation at the same place on a chromosome. It can also refer to different sequence variations for a several-hundred base-pair or more region of the genome that codes for a protein. 

All are heterozygous tall (Tt). In F2 generation genotypic ratio will be 1:2:1. , i.e. 1 homozygous tall: 2 heterozygous tall: 1 homozygous dwarf. In dihybrid cross two traits are considered together.
