A zygote has the unique ability to make any kind of cells; your heart, nerves, muscles… you name it and it comes from this tiny zygote. This potential of the zygote to develop into any kind of cell found in the human body is called totipotency, and is why a zygote can create an...
How many chromosomes are in a zygote? How many chromosomes are there in the metaphase of mitosis? How many chromosomes are in a cell at the beginning of meiosis? Which stage of meiosis results in 2 cells with 46 chromosomes? What is somatic cell hybridization?
However, there has not been a consistent and standard definition of cell types, although it is critical for reproducible investigation. It is often unclear if cell types defined by different phenotypic features agree with each other nor which feature is the right one to define cell types. ...
This is true of how animals evolve, but in the specific case of the CHICKEN and the EGG, we haven’t roped in evolution to answer this conundrum. As it turns out, the answer to this question is not that difficult. To answer it simply, one day there was a bird that wasn’t a chic...
a cross between two hetero-zygotes would produce what phenotype ratio? If there are 2 alleles, A and a (1 dominant and 1 recessive), and two heterozygotes mate, what is the ratio of expected genotypes? What are the possible types of gametes that these individu...
1). This simple model works well most of the time, with the main blue eye gene OCA2. We can draw pedigrees showing homozygote blue- and homozygote brown-eyed parents having heterozygote brown-eyed children and then grandchildren who may be homozygote or hererozygote blue- or brown-eyed ...
:a gamete indistinguishable in form or size or behavior from another gamete with which it can unite to form a zygote. Is sclerotium a fruiting body? S. sclerotiorum sclerotia can viable spores for at least three years and germinate to produce fruiting bodies calledapothecia, which are small,...
An egg is the organic vessel containing the zygote in which an embryo develops until it can survive on its own, at which point the animal hatches. An egg results from fertilization of an egg cell. Ovum (cytology) The female gamete in animals; the egg cell. Egg A female gamete; an ovum...
Cells may also divide without any increase in total size, for example during zygote cleavage. On the other hand, the replication of DNA during the cell cycle not followed by mitosis is a common phenomenon called ‘endoreduplication’. The resulting high-ploidy cells are generally also much ...
