Question

Draw 6 monohybrid crosses, pedigree chart and punnett squares of ear lobe and colour vision​

Answer 1

Answer:

In humans, controlled crosses cannot be made, so geneticists must resort to scrutinizing family records in the hope that informative matings have been made that can be used to deduce dominance and distinguish autosomal from X-linked inheritance. The investigator traces the history of some variant phenotype back through the history of the family and draws up a family tree, or pedigree, using the standard symbols given in Figure 4-17.
