Does meiosis occur after fertilization? What is produced as a result of meiosis? What process occurs when chromosomes are in the tetrad? What part of the cell divides during meiosis? What would happen if synapsis did not occur in meiosis?
What is inheritance in biology? On the molecular level, what exactly is a mutation? What does genetic engineering have to do with oncogenes? What is a motif in biology? What is translocation? What is a tetrad? What is hybrid speciation?
Meiosis is similar to mitosis in many ways, but there are a couple of important differences. First of all, even though meiosis starts with a diploid cell (a primary oocyte or primary spermatocyte), its end products are 4 haploid daughter cells, each with 23 chromosomes. Instead of being c...
Terminology: Tetrad,Bivalent, Dyad, Monad: The paired chromosomes at prophase I can be called a tetrad or bivalent. A chromosome consisting of just one chromatid is a monad. If it has two chromatids, it is a dyad. ... Timing of meiosis: Prophase I arrest in human females. Which is th...
A. Mitosis B. Meiosis What is the type of cell division in the formation of gametes? What is segregation and when does it occur in meiosis? What kind of cell division takes place in meiosis? Identify the type of cell division from the description. Description:...
In this lesson we'll go over what cell division is in different types of cells and look at the factors that stop cells from dividing. We'll also learn what happens when cell division doesn't stop. What Is Cell Division? All life starts with a single cell. That cell multiplies as we...
It undergoesmeiosis forming usually a linear, rarely T-shaped tetrad. The chalazal megaspore after 3 nuclear divisions forms an 8-nucleateembryosac. The mature embryosac is spindle shapedMarkteachingK.teachingFulkteaching&teachingAngelateaching

Definition:Meiosis is reduction division that occurs only in germ cells where gametes are produced with half the chromosome number to that of the parent cell. This reduction is essential for maintenance of chromosome number in a species.
Furthermore, meiosis allows the production of genetically variable gametes. This is because bivalent formation and genetic mixing occur at points known as chiasma during prophase. Bivalent or tetrad is an association of homologous chromosomes formed during the prophase I of meiosis. Chiasma is the ...
