Some steps in cell division are shown below: 1. chromosomes condense and pair up 2. segments of dna of sister chromatids twist and cross 3. exchange of dna occurs between chromosomes 4. four daughter cells are created that are haploid which of the following steps is least likely to occur during meiosis 1?
D. step 4
the cell divides into two daughter cells during meiosis 1
Bcoz only 2 haploid cells are formed at the end of meiosis 1st...at the end of meiosis 2nd.. 4 haploid cells formed
In meiosis, the breaking up of chromosomes occur to form new daughter cells. The chromosomes break into haploid parts and then the two daughter cells formed then twist and exchange their genetic information. Division into four daughter cells is less likely to occur during meiosis 1.
The correct answer would be step 4.
Meiosis I is the reduction division which results in the formation of two haploid daughter cells from a single parent cell.
It includes prophase I, metaphase I, anaphase I, and telophase I.
During prophase I, first DNA gets condense to form chromosomes. Each chromosome consists of two sister chromatids. Then the event of crossing-over (exchange of genetic material) takes place.
By the end of meiosis I, the homologous chromosomes are separated into two daughter cells.
Meiosis II results in the formation of four haploid daughter cells.
