What two structures make up a single replicated chromosome?
DNA and Protein
What are two rod like parts that make up a chromosome are called?
Chromatids
How many chromatids have one chromosome?
Two (2). Before DNA replication, each chromosome is composed of a single chromatid. After replication, but before separation of the chromatids during anaphase, this is true.
What two identical bodies make up a duplicated chromosome?
Somatic cell chromosome is made of two identical chromatids
How many chromosomes are in a homologous pair?

Why does a puppy always have two alleles for every trait?
Because of homologous pairs of chromosomes. One chromosome from the puppies mother and one from the father make up the 78 chromosomes of dogs. One allele on the mom chromosome and one on the dad chromosome, even if there are more than two alleles for the trait only two will be represented in the genome.
do genes make chromosome?
no
A species that contains two copies of each chromosome is called?
A species that contains two copies of each chromosome is called diploid. Each pair of chromosomes, one from each parent, make up a diploid set in the organism.
How much -in amount- is in a replicated DNA chromosome as to that in an unreplicated chromosome?
These two amounts are Equal.
A somatic cell having two of each type of chromosome has chromosome number?
A somatic cell with two of each type of chromosome has a diploid chromosome number. This means that the cell has a complete set of chromosomes, one from each parent.
Which are the two main parts that make up a chromosome?
A centromere and a pair of sister chromatids
