They became adapted to their new environment and became new species which then were not able to produce fertile offspring.
Close breeding and line-breeding are a part of the inbreeding system. Inbreeding refers to the cross between relatives.

Close breeding and line-breeding are a part of the inbreeding system and these techniques involve the obtention of pure (homo-zygous) lines.
Autogamous plants show better phenotypic features when they are pure (homo-zygous) lines.

Answer:
True
Explanation:
Point mutations arise when a single amino acid base is changed. This could cause some differences in the organism or it may not. Manufactured point mutations in model systems such as yeast offer a powerful tool to examine the function of different amino acids in a protein.
There are three types of point mutations
- Silent: these mutations have a single residue change but it does not affect the amino acid that is being coded. There is no change to the wild type
- Nonsense: will cause a stop or start or gain of start/stop codon.
- Mis-sense: will cause a change of amino acid residue. There are two types of mis-sense Conservative and non-conservative. The former will cause a change in amino acid base to one that has similar properties while the former will change to an amino acid of different properties often having different traits than the wild type.
