If all of the chromosomes fail to separate in meiosis, then nondisjunction can result in a diploid gamete. This is a type of chromosomal mutation. In animals, a zygote produced from the union of a mutated diploid gamete and a normal haploid gamete will have triploidy, which is lethal. In plants, this is not necessarily lethal.
What else can I help you with?
Does the process of meiosis result in the production of diploid cells?
No, the process of meiosis results in the production of haploid cells, not diploid cells.
Does meiosis result in the formation of haploid or diploid cells?
Meiosis results in the formation of haploid cells.
What does a diploid cell inside a basidium produce as a result of meiosis?
A diploid cell inside a basidium produces four haploid spores as a result of meiosis. These spores can germinate to form new haploid organisms.
What happens if nondisjunction occurs during meiosos?
If nondisjunction occurs during meiosis the result could be a wide range of mutations. Most likely it would result in mosaicism meaning there will be a mixture of affected cells and non affected cells.
How does nondisjunction during meiosis I and II affect the distribution of chromosomes in gametes?
Nondisjunction during meiosis I and II can lead to an unequal distribution of chromosomes in gametes. This can result in gametes having an extra chromosome (trisomy) or missing a chromosome (monosomy), which can lead to genetic disorders in offspring.
If nondisjunction occurs in meiosis II for one chromosome what will be the result at the completion of meiosis?
If nondisjunction occurs in meiosis II for one chromosome, the result would be that one gamete receives an extra copy of the chromosome and one gamete lacks that chromosome. This results in aneuploidy in the offspring, which can lead to genetic disorders such as Down syndrome.
Is fragile x syndrome a result of nondisjunction during meiosis?
yes . it is . nondisjunction is takes place during meiosis.
Does the process of meiosis result in the production of diploid cells?
No, the process of meiosis results in the production of haploid cells, not diploid cells.
What is a failure of homologous chromosomes to separate in meiosis?
A failure of homologous chromosomes to separate in meiosis is called nondisjunction. This can result in cells with an abnormal number of chromosomes, leading to genetic disorders such as Down syndrome. Nondisjunction can occur during either the first or second division of meiosis.
Does meiosis result in the formation of haploid or diploid cells?
Meiosis results in the formation of haploid cells.
What does a diploid cell inside a basidium produce as a result of meiosis?
A diploid cell inside a basidium produces four haploid spores as a result of meiosis. These spores can germinate to form new haploid organisms.
When chromosomes do not part in meiosis like they should?
When chromosomes do not separate properly during meiosis, it can lead to an incorrect number of chromosomes in the resulting gametes. This condition is known as nondisjunction and can result in genetic disorders like Down syndrome in humans.
What happens if nondisjunction occurs during meiosos?
If nondisjunction occurs during meiosis the result could be a wide range of mutations. Most likely it would result in mosaicism meaning there will be a mixture of affected cells and non affected cells.
What are tetrasomics?
Addition of a pair of chromosomes to a diploid set results in tetrasomic condition. Tetrasomics may be represented as 2N+2. Tetrasomics may arise when two abonormal gametes produced as a result of non-disjuction unite, with each gamete carrying an extra chromosome of the same pair as shown below. AABBCCDD a diploid cell----meiosis and non disjuction AABC Gamete carrying an extra chromosome--- BC Gamete short of one chromosome. Now if this Gamete (AABC) unites with another gamete of the same kind (AABC), we get tetrasomic AAAABBCC.
The faillure of chromosomes to separate during meiosis is called?
The failure of chromosomes to separate during meiosis is called nondisjunction. This can result in an incorrect number of chromosomes in the daughter cells, leading to genetic disorders such as Down syndrome.
How does nondisjunction during meiosis I and II affect the distribution of chromosomes in gametes?
Nondisjunction during meiosis I and II can lead to an unequal distribution of chromosomes in gametes. This can result in gametes having an extra chromosome (trisomy) or missing a chromosome (monosomy), which can lead to genetic disorders in offspring.
What are the main differences between meiosis 1 and 2?
meiosis 1 the result is 2 different cells with diploid (or duplicated haploids) chromosomes and for meiosis 2, the result is 4 different haploid cells
