Chiasmata are evidence that crossing over has occurred during meiosis, specifically in prophase I. They are the points where homologous chromosomes exchange genetic material, resulting in genetic recombination. This process increases genetic diversity in gametes, which is crucial for evolution and adaptation in populations. The presence of chiasmata can be observed under a microscope during cell division.

Does the holocaust exist?
no __ Given the mountain of evidence - film, eye witness, court testimony, photographs, official gov documents - that show it occurred, I'd say yes it did.

What if DNA profiling was discovered 100 years earlier?
if it was discovered 100 years ago i believe racial conflict wouldn't have occurred because of evidence and proof. Also that we would be such a much more advance world then what we are today.
The Bolshevik Revolution occurred in what country?

What are the event that occurred in tonkin gulf?
The Vietnam War is the event that occurred in the Tonkin Gulf.
X shaped regions created when chromosomes crossover are called?
When chromosomes crossover the x shaped region created is called a chiasmata. These chiasmatas allow chromosomes to exchange of genetic materials.
Are Fizzing or foaming evidence that a chemical change may have occurred?
yes it s an evidence that a chemical change has been occurred
What is the only cytological evidence of crossing over?
Chiasmata are the only cytological evidence of crossing over. They are physical manifestations of genetic recombination formed during prophase I of meiosis when homologous chromosomes exchange genetic material.
During what event of meiosis will chiasmata be observed?
Chiasmata are observed during the prophase I of meiosis. Chiasmata are the physical manifestation of crossing over between homologous chromosomes, where genetic material is exchanged between chromatids.
Chiasmata form between.?
Sister chromatids
How does chiasmata contribute to genetic variation?
Jh
What is the difference between Chiasma and Chiasmata?
Chiasma refers to the physical site of crossover between homologous chromosomes during meiosis, facilitating genetic recombination. Chiasmata are the visible manifestations of chiasmata, appearing as X-shaped structures that hold homologous chromosomes together before they separate during meiosis.
Crossing over points are called?
chiasmada
What is the meaning chiasmata and crossing over?
Crossing over:is a process of (breakage) and (exchange) of parts between two homologous chromatids .Each bivalent (a pair of same chromosomes ) is called a tetrad . Along the length of each bivalent one or more X shaped connections between (non-sister chromatids ) are found ;these CHIASMATA are places where crossing overs have occurred .I hope that's helped .ZIZO-Saudi Arabia
Complete reproduction isolation is evidence that what has occurred?
speciation
What is quantitative evidence?
Quantitive evidence is evidence that has to do with numbers. For example. the magnitude of an earthquake the time the earthquake occurred and the length of the earthquake are all types of quantitive evidence
X-shaped regions created when chromosomes crossover are called?
chiasmata
