What is the type of asexual reproduction does an organism break into fragments, and each fragment develops into a fully grown individual

Back

Fragmentation

Front

• These are pairs of chromosomes, one from each parent, that carry genes for the same traits. They are similar in size and shape but may have different versions of the genes.

Back

Homologous Chromosome

Front

These are identical copies of a single chromosome that are joined together during cell division. They are formed through DNA replication and separate during mitosis and meiosis.

Back

Sister Chromatids

Front

What is the difference between homologous chromosomes and sister chromatids?

Back

Back

Front

This is a type of cell division that produces two daughter cells genetically identical to the parent cell. Each daughter cell receives a full set of chromosomes.
