Question

meiosis: interphase & homologous chromosomes
label the diagrams & type the numbers of each genetic component.
before dna replication after dna replication
do this for a human cell
number of chromosomes
number of homologous pairs
number of chromosomes
number of homologous pairs
number of chromatids
key
maternal chromosome came from the mother paternal chromosome came from the father

Explanation:

Step1: Recall human chromosome number before DNA - replication

In a human cell before DNA replication, the number of chromosomes is 46. There are 23 pairs of homologous chromosomes. Each chromosome is a single - chromatid structure at this stage.

Step2: Analyze changes after DNA replication

After DNA replication, the number of chromosomes remains the same (46). The number of homologous pairs is still 23. But each chromosome now consists of two sister chromatids, so the number of chromatids is 92.

Answer:

Before DNA replication:
Number of chromosomes: 46
Number of homologous pairs: 23
After DNA replication:
Number of chromosomes: 46
Number of homologous pairs: 23
Number of chromatids: 92
