What are tetrads?

Bivalents or Tetrad of homologous chromosomes consisting of four synapsed chromatids that become visible during the Pachytene stage of meiotic prophase or A four-part structure that forms during the prophase of meiosis and consists of two homologous chromosomes, each composed of two sister chromatid (MORE)

How do bivales move?

Many bivalves have one "foot" made of the same soft material as their bodies, and they use this to push themselves around. Some bivalves, such as scallops, can shoot water from their bodies with enough force to propel them away from any danger.

How many chromatids are in a tetrad?

All tetrads contain four chromatids. Each "leg" is one chromatid. 2 Tetrad = 2 homologous chromosomes 1 homologous chromosome has 2 chromatids joined together by a centromere. That means that there are four chromatids in a tetrad

What is the difference between was and were?

Was is singular and applies to one person. . Were is plural and applies to more than one person. (except in singular "you were") . eg I was ready, but you three were not ready. .

How do tetrads form?

Tetrads form in Prophase 1. As the chromatin condenses, special proteins cause the homologus chromosomes to stick together in pairs. The resulting structure has 4 chromatids and is called a tetrad.

What is a bivale?

Aquatic mollusk ,like a scallop or a mussel are bivale which meananimals that consist in two hinged shells .

What is difference between the and a?

THE is used when talking about a specific item for example you would say "put it on THE table" not "put it on A table" when u say THE table u mean that specific table, but if u say A table then it could mean any table available

Tetrads are seen where?

Tetrads are groups of four and can refer to genetics, generalrelativity, or chromosomal formation. A tetrad is a group of fourchromatids that are in the first stages of meiosis.

Dyad vs tetrad?

A dyad is a group of two, a tetrad is a group of four; for a group of three you can use the term triad.

A tetrad is composed of?

Tetrads are formed of 2 homologous chromosomes, which are crossing over so there is a total of 4 chromatids. :D

What happens in tetrad stage?

listen to the song butterfly by bassnecter and you will no longer have the will to do anything but ski in white, majestic snowy, awesome, beast tron mountains.

When does chromosomes form tetrads?

the chromosomes form to tetrads because the cemical property with the cemical will not communtacate so you would need a genorater magnifinglass microscope 7000 . then you could see the cemiclas witch are ununununium , calcuim iron Ect. There are more than 100 cemicals in the world.

When do the homologous chromosomes form tetrads?

In Prophase I of meisosis. A tetrad is also called a bivalent. This happens so that crossing over can occur between non-sister chromatids. Crossing over is a source of genetic variability in the resulting daughter cells, gametes.

Are tetrad and homologous chromosomes the same?

Homologous chromosome is when a pair of chromosomes containing the same linear gene sequences, each derived from one parent, and a tetrad is formed when 2 homologous chromosomes join together

What is the tetrad formation?

During Prophase 1, pairs of homologous chromosomes line up to form tetrads(T) C represents a pair of centrioles that will migrate to the one end of the cell. The term tetrad refers to the four chromatids of the paired homologous chromosomes. Remember that during prophase, each chromosome has two str (MORE)

What is the difference between has or have?

easy! has means you have something at this minute for example: he still has that dog. and have is when you have something with you for example: look what i have! or can i have that please? i hope that helped!

What is the difference between these and this?

'These' indicates that you are reffering to something plural, e.g there is more of that thing than just 1. "Look at these apples" 'This' indicates you are refering to something singular, which means that there's only 1 of them. "Look at this apple" 'this' indicates singular while 'these' (MORE)

What is tetrad and why is it important?

A mega or microspore mother cell after undergoing meiosis results in to 4 haploid cells. To begin with these cells (spores) remain enclosed in the cell wall of mother cell, hence called tetrad. The spore further develops in to egg cell or male gametes and are important for sexual reproduction.

What is the difference between you-- and --i?

well I am me and you are You so being me i refer to myself as I and you being yourself are not me so by definition are really an unknown tthing and therefore Alien which is something else altogether and now I, who am me are afraid of you, who are an extraterrestrail all of a sudden and could be an i (MORE)

What is the difference between 'where' and 'were?

"Where" indicates a place, such as "Where are you?" or "That restaurant is where Timmy choked on a crab." "Were," on the other hand, has to do with something that happened in the past, such as "We were working on homework" or "Were you really choking on a crab, Timmy?" Take note that Were is to be (MORE)

How many tetrads in humans?

A tetrad is the pairing of homologous chromosomes. A human offspring inherits 23 chromosomes (N) from each parent upon fertilization, giving the offspring 46 chromosomes (2N). In meiosis, homologous chromosomes (N from mom and N from dad) come together and form a tetrad, which consists of 2 homologo (MORE)

What is the difference between monad dyad and tetrad?

Chromosomes come in 2 forms, depending on the stage of the cell cycle. The monad form consists of a single chromatid, a single piece of DNA containing a centromere and telomeres at the ends. The dyad form consists of 2 identical chromatids (sister chromatids) attached together at the centromere. (MORE)

What is the difference between you and me?

Every person is different in their own special way. None of us are the same. There is a different genetic code in every person. Also, nobody has the same finger print, not even family or twins!

Why do tetrads exchange DNA?

To increase (gene) variation; in other words to make the chances of you looking different from someone else higher.

How is forming tetrads in prophase 1 different from mitosis?

Tetrads don't form in mitosis. Tetrads form so that chromosomes can undergo crossing over which is a form of genetic recombination. The products of meiosis are gametes which ensure genetic diversity in subsequent generations. In mitosis, the daughter cells are genetically identical to the parent cel (MORE)

When in meiosis do 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.

Is a mule a tetrad?

No a mule is not a tetrad, this is due to the fact that the mule has 63 chromosomes. Mules are a hybrid between the horse and the donkey, and are unable to reproduce due to the uneven number of chromosomes.

What does the term TETRAD stand for?
