Explain the relationship between homologous chromosomes and

Explain the relationship between homologous chromosomes and the relationship between sister chromatids. How are these relationships different from one another? Homologous chromosomes and sister chromatids are synonymous They both have the same genes (but often different alleles) and originate from different parents Homologous chromosomes are the exact copies of the single double-helical molecule of DNA that was present in the unreplicated chromosome before S phase. Sister chromatids are similar in size and shape, they have the same genes and originate from different parents. Homologous chromosomes become sister chromatids during G_2 phase of a cell cycle. Thus homologous chromosomes take place in a growing cell and sister chromatids can be found during mitosis. Homologous chromosomes are similar in size and shape, they have the same genes and originate from different parents sister chromatids are found in replicated chromosomes and contain exact copies of the single double-helical molecule of DNA.

Solution

The correct option if the fourth one:

Homologous chromosomes are similar in size and shape. they have the same genes and originate from different parents. Sister chromatids are found in replicated and contain exact copies of the single double helica; molecule of DNA.

Actually homologous chromosomes can be defined as the chromosomes same in shape and size, and carry the genes of contrasting chaacteristics..Chromatids whic separate in metaphase of cell division are sister chromatids.
