Question

Fill in the chart below by writing in the genotype and phenotype for each of the following individuals.

Answer 1

5. Let the allele be represented by the letter D (dominant) and d (recessive) - not sure if there was any other information about what the trait is

Your table has to look like this:

Homozygous dominant   Genotype is DD   Phenotype is Dominant trait

Heterozygous  Genotype is Dd    Phenotype is dominant trait

Homozygous recessive   Genotype is dd   Phenotype is recessive trait

6. Punnet square

Parents are True breeding black (BB) and True breeding white (bb)

       B     B

b    Bb   Bb

b    Bb   Bb

You can imagine the squares around that. So, all the offspring would be Bb (heterozygous) so all would phenotypically look black.
