What stage in meiosis the tetrads separate?
During meiosis, tetrads, which are connected by a synapse partway down their length, line up along the cellular equator during metaphase I. The tetrads are then separated during anaphase I as the spindle fibers pull the tetrads apart towards opposite sides of the cell.
During which stage of meiosis do synapsis and the formation of tetrads occur?
The formation of tetrads are formed during p1(prophase 1)
Crossing-over is the exchange of reciprocal segments of DNA between homologous chromosomes true or false?
It's true that crossing over is the exchange of reciprocal DNA parts between homologous chromosomes.
When tetrads are formed?
during prophase 1
A diploid horse has 66 chromosomes How many tetrads does a horse have in a meiotic cell?
a horse has 64 chromosomes That said, if you assume it DOES have 66, there would be 33 tetrads.
What must happened before mitosis can begin?
The chromosomes must be duplicated. the real answer: DNA replicates and forms tetrads
What happens in meiosis during phase 1?
The homologous pairs of chromosomes line up together forming tetrads. During this time, chromatids from the homologous chromosomes cross over and exchange segments so that each chromatid contains both maternal and paternal DNA.
What is the role of crossing over In genetic variation?
to make sure that tetrads cross over and swap DNA, giving the offspring similar DNA to the parents. im pretty sure this is right :)
What is the role of crossing in ensuring genetic variation?
to make sure that tetrads cross over and swap DNA, giving the offspring similar DNA to the parents. im pretty sure this is right :)

Describe crossing over and independent assortment.?
- Crossing over is the event in which non-sister chromatids of homologous chromosomes swap or exchange DNA segments. This produces new gene combinations and only occurs in prophase 1 when tetrads form. independent assortment is the random orentation of pairs of homologous chromosomes at metaphase 1

What is the exchange of DNA material at synapsis?
crossing over
When do tetrads form in a cell?
1492
What is the exchange of DNA material in synapsis called?
genetics materials
What do protists exchange during conjugation?
Genetic Material (DNA).

The formation of tetrads are formed during p1(prophase 1)
