Answer:
Statement 1 - dihybrid cross, statement 2 - replication,
statement 3 - multiple alleles, statement 4 - mutation,
statement 5 - codominance.
Explanation:
Dihybrid cross is a term used when two organisms breed, have two genes for two different characters or trait.
Statement 1 - dihybrid cross
DNA polypeptide chains separate and each one of them acts as the template for forming new chain is, the process is DNA replication.
statement 2 - replication
If a gene has more than two alleles for a particular trait this condition is known as multiple alleles.
statement 3 - multiple alleles
A mutation is a mistake or error during DNA replication, it can be during reading or copying.
statement 4 - mutation
If a gene has two alleles and both alleles show their effect in the phenotypes.
statement 5 - codominance.
