How do differ chromatids differ from homologous chromosomes?
Sister chromatids are identical while homologous chromosomes are merely similar.They are different because they separate the cells and then they become babies but only the homologous chromosomes do.
What are chromosomes that appear identical are called?
Chromosomes that appear identical are called homologous chromosomes. They carry the same genes in the same order but may have different versions of those genes (alleles). Homologous chromosomes are inherited, one from each parent, and are important for genetic variation and the process of meiosis.
What is the difference between a chromatid and a sister chromatid?
Homologous chromosomes is a pair made of a paternal and maternal chromosomes. But sister chromatid is either pairs of paternal or maternal chromosomes
Why are chromatids not identical?
Chromatids are not identical because they undergo genetic recombination during meiosis, where segments of DNA are exchanged between homologous chromosomes. This process introduces genetic variation, leading to chromatids with different combinations of alleles. Additionally, mutations can also occur during DNA replication, further contributing to differences between chromatids.
What condenses into an X shape before mitosis?
Chromosomes condense into an X shape before mitosis. During prophase, the chromatin in the nucleus begins to condense and coil, forming distinct X-shaped structures known as chromosomes. This condensation allows the chromosomes to be easily moved and segregated during cell division.
Difference between sister chromatids and homologous chromosomes?
Homologous chromosomes are individual chromosomes inherited from each parent. Sister chromatids are the result of DNA replication, and the are identical.

What two identical bodies make up a duplicated chromosome?
Somatic cell chromosome is made of two identical chromatids
Are sister chromatids or homologous chromosomes more similar?
Sister chromatids are more similar to each other because they are exact copies of each other formed during DNA replication. Homologous chromosomes, on the other hand, are pairs of chromosomes that contain genes for the same traits, but may have different versions of those genes.
How do sister chromatids differ from homolohous chromosomes?
Sister chromatids are exact copies of each other produced during DNA replication in a cell, connected at the centromere. Homologous chromosomes are pairs of chromosomes that carry the same genes in the same location, but may have different alleles. Sister chromatids are produced in preparation for cell division, while homologous chromosomes are inherited from each parent.
What are chromosomes that appear identical are called?
Chromosomes that appear identical are called homologous chromosomes. They carry the same genes in the same order but may have different versions of those genes (alleles). Homologous chromosomes are inherited, one from each parent, and are important for genetic variation and the process of meiosis.

Homologous chromosomes is a pair made of a paternal and maternal chromosomes. But sister chromatid is either pairs of paternal or maternal chromosomes
What is the difference between recombinant and parental chromatids and how do they arise?
Recombinant chromatids have undergone genetic recombination, resulting in the exchange of genetic material between homologous chromosomes. This process can occur during meiosis. Parental chromatids, on the other hand, have not undergone genetic recombination and contain the original combination of alleles from the parent chromosomes.
What division of meiosis splits chromosomes?
In anaphase I of meiosis, the homologous pairs of chromosomes separate. Due to DNA replication and crossing over during prophase I, these chromosomes consist of a pair of non-identical sister chromatids. During anaphase II of meiosis, the sister chromatids separate into individual chromosomes.
Why do you use non-sister chromatids to demonstrate crossing over?
Non-sister chromatids are used to demonstrate crossing over because they contain different alleles and genetic information, leading to the exchange of genetic material between homologous chromosomes. This process results in genetic recombination, increasing genetic diversity among offspring.
Why are chromatids not identical?
Chromatids are not identical because they undergo genetic recombination during meiosis, where segments of DNA are exchanged between homologous chromosomes. This process introduces genetic variation, leading to chromatids with different combinations of alleles. Additionally, mutations can also occur during DNA replication, further contributing to differences between chromatids.
