3. a) joint earlobe and free ear lobe
b) roller tongue and non roller tongue
4. In biology, a gene is a sequence of DNA or RNA that codes for a molecule that has a function. During gene expression, the DNA is first copied into RNA.

6. Bcoz the tails were artificially removed and did not help the mice in better adaptation of their environment.It was not an necessary variation.
7. A monohybrid cross is a genetic mix between two individuals who have homozygous genotypes, or genotypes that have completely dominant or completely recessive alleles, which result in opposite phenotypes for a certain genetic trait.
