Summary Introduction

To describe:

The reasons for single trait might not show 3:1 ratio of phenotype in the F2 generation of a cross between true-breeding strains, and also to describe the reason for a pair of traits might not show 9:3:3:1 ratio of phenotype in the F2 generation of a cross between true-breeding strains.

Concept introduction:

The genotype of an organism is defined as the genetic code present in its cells. This genetic constitution of an individual influences many of its traits and characteristics. A genotypic ratio refers to the distribution of the different allelic combinations regardless of the fact, if they are expressing the same trait phenotypically or not.

If you transplant trunk neural crest into the cranial neural crest region of a developing embryo, will you see the donor tissue form cartilage? Does the neural crest only give rise to two cells in the developing embryo, and is essential for lamprey to develop their jaw structure? Does a multipotent neural crest cell that is receiving Wnt signals become a Chromaffin cell?
