Tongue rolling allele is dominant (R)

Non tongue rolling allele is recessive (r)

Both parents are both heterozygous for the tongue rolling gene.

What is the probability that:

a) their firstborn child is a non tongue roller?

b) the second child is also a non tongue roller?

c) the third child is a tongue roller?

Farmer Ted has a curly tailed male pig and wants to know whether it is pure breeding or not. He has asked you to find out for him. He pays you $400.

Curly tails (T) are dominant over straight tails (t).

Write your answer on your book

Punnett Squares are used to determine the probability of an offspring having a particular genotype.

Test Cross & Pure Breeding

Pure Breeding = Homozygous Genotype

In genetics a test cross is used to determine if an individual exhibiting a dominant trait is homozygous or heterozygous (i.e. pure breeding or not)
