Does the male or female gamete contribute more chromosomes to the fertilized egg?
Each gamete contributes an equal number of chromosomes to the fertilized egg. The male gamete (sperm) typically contains 23 chromosomes, and the female gamete (egg) also contains 23 chromosomes. Together, they combine to form the full set of 46 chromosomes in a normal human cell.
What is the definition of polyploidy mutation?
Polyploidy mutation is a type of mutation that results in an organism having more than two complete sets of chromosomes. This can lead to increased genetic diversity and potentially new traits in the organism.
Can humans have more than 46 chromosomes?
Yes, humans can have more than 46 chromosomes due to genetic disorders such as Down syndrome, which is caused by having an extra copy of chromosome 21. Having additional chromosomes can lead to developmental and health issues.
How many chromosomes do plants have?
Unlike animals, plants are a lot more varied in the number of chromosomes they can have. 'Anywhere between 2 and at least 12(?)' is a decent starting assumption.
Any species with a multiple set of chromosomes is?
Polyploid. This means they have more than two sets of chromosomes, which can result in increased genetic diversity and variations in traits among individuals. Examples of polyploid species include strawberries and wheat.
Does gamete have more chromosomes then a zygote?
No, a zygote has 46, a gamete has 23
Does the male or female gamete contribute more chromosomes to the fertilized egg?

How can a human with 47 chromosomes be produced?
This occurs due to nondisjunction, in which one or more homologous pairs of chromosomes do not separate during anaphase I, or sister chromatids do not separate properly during anaphase II of meiosis. The resulting daughter cells (gametes) will have either 22 or 24 chromosomes. If the gamete with 22 chromosomes unites with a normal gamete with 23 chromosomes, the offspring will have 45 chromosomes (23 + 22). If the gamete with 24 chromosomes unites with a normal gamete, the offspring will have 47 chromosomes (23 + 24). These are usually lethal conditions.
What happens if the gametes aren't haploid?
The whole purpose of reducing the gamete to contain half the number of normal chromosomes is so that normal chromosome numbers can be achieved again when the gametes fuse to form a zygote. If the gamete is not halved, polyploidy results. This is a generic term to describe having more than the normal number of chromosomes.
What is a polyploid animal?
Diploid: adj. 1 Double or twofold. 2 Having a homologous pair of chromosomes for each characteristic except sex, the total number of chromosomes being twice that of a gamete.-n 1. a diploid cell. 2. An individual characterized by a diploid chromosome number.It has two copies of each chromosome.
How plant cells have more than 2 complete sets of chromosomes?
69 and phil
How are gamete different from zygotes compare the number of chromosome in each?
Gamete is the term that refers to the individual haploid sex cells, the egg or the sperm, and contains only half of the necessary genetic information for a new organism. A zygote is the diploid result of fertilization between an egg and sperm, which will ultimately grow into the organism.
What are the advantages of having large numbers of chromosomes?
Having a large number of chromosomes can provide genetic diversity and increase the potential for adaptation to changing environments. It can also allow for more efficient gene regulation and reduce the risk of harmful mutations affecting essential genes. Additionally, large numbers of chromosomes can support complex genetic interactions and contribute to species evolution and speciation.
Why do potatoes have more chromosomes than humans?
The number of chromosomes of a species has little to do with the complexity of the organism or the amount of DNA. The reason for this is, chromosomes are known to break and form two or more new chromosomes, or fuse into one. The chromosomes of the potato and the potato lineage may have undergone many such changes, and the human lineage may have undergone a different series, resulting in the potato having more chromosomes.
Do people with autism have babies?
Most autistic people are capable of reproducing, unless they have a complex chromosome deficiency, such as males having 2 X chromosomes or females having 3 or more X chromosomes.
What is the definition of polyploidy mutation?
Polyploidy mutation is a type of mutation that results in an organism having more than two complete sets of chromosomes. This can lead to increased genetic diversity and potentially new traits in the organism.
The presence of complete extra sets of chromosomes?
Polyploidy is the heritable condition of possessing more than two complete sets of chromosomes. Polyploids are common among plants, as well as among certain groups of fish and amphibians.
