Answer:
A punnet square can be described as a diagram which is made to check the outcomes of a cross.
To check the probability of the offsprings of a cross between homozygous dominant thumb shape parent with a homozygous recessive thumb shape parent, let's draw a punnet square:
t t
T Tt Tt
T Tt Tt
The results of the punnet square depict that:
Genotype: All of the offsprings will be heterozygous for the thumb shape trait. Tt will be the genotype.
Phenotype: All of the offsprings will show the thumb shape like the thumb shape of the dominant parent.
Answer:
common ancestor.
Explanation:

Evidence from fossil's records are used to study that today how much organisms have changed themselves according to the environmental changes on earth. DNA and genetic codes mainly shows the shared common ancestry.
