Homologous chromosomes vs sister chromatids.

Homologous chromosomes vs sister chromatids quizlet. However they are non identical. This means that at the gene level each of the homologous pair could be carrying different alleles. Show full abstract turn lets the recombination.

In the case of chromatids each sister chromatid is an exact replication of the other. The pairing of homologous chromosomes during prophase 1 lets the crossing over to occur and crossing over between non sister chromatids in. Chromosomes may or may not have an exact trait like that of a parent.

Sister chromatids are made up of either a maternal or paternal chromosome. Homologous chromosomes may contain same or different alleles of the same gene. May contain different versions of some gene.

However during mutation s they will have slight differences in which case they may be heterozygous. The 2 chromosomes of a homologous pair are ind chromosomes that were inherited from dif parents. Also they vary widely in their size the location of centromere staining properties the relative length of the two arms on either side of the centromere and constricted sites.

Identical carry the same versions of all their genes because one was produced as an exact copy of the other homologous chromosomes. Homologous chromosomes are exact to each other. Therefore they are not the same.

On the other hand sister chromatids are the exact duplicates and arise by duplication when the chromosomes undergo mitosis. Homologous chromosomes are made up of both maternal and paternal chromosomes. All animals carry their genetic information in chromosomes and have characteristic number of chromosomes in their cells.
