What is the proper scientific word for sex cells?
I think you are going for "gametes". gametes
Mendels law of segregation states that?
Mendels law of segregation states that alleles in the pair separate when gametes are formed.Mendel's law of segregation states that allele pairs separate or segregate during gamete formation, and randomly unite at fertilization.There are four main concepts related to this principle. They are as follows:A gene can exist in more than one form.Organisms inherit two alleles for each trait.When gametes are produced (by meiosis), allele pairs separate leaving each cell with a single allele for each trait.When the two alleles of a pair are different, one is dominant and the other is recessive.
What does haploide mean?
"Haploid" refers to the number of chromosomes in a gamete.You may talk of a haploid number, haploid nucleus, haploid cell, or even a haploid organism, which is an animal or plant whose body cells contain the haploid number of chromosomes. Examples of haploid organisms are male honey bees and the leafy parts of mosses.The haploid number is often the number of chromosomes in a single set (n); this is true of us humans, for example. Our gametes contain one set of chromosomes (n = 23), and our somatic (body) cells two sets (2n = 46).However, some organisms have more sets; some wheat is tetraploid (4n) and its gametes are therefore 2n. In these cases the number of chromosomes in a single set (n) may be called monoploid.
Write mendel'a law of segregation?
explains the results of his cross between F1 tall plants. he concluded that the two alleles for each trait must separate when gametes are formed. a parents,, therefore, passes on at random only one allele for each trait to each offspring.
What is segregation and what is the result of segregation?
Segregation is separation:1. The act of segregating, or the state of being segregated; separation from others; a parting.2. (Science: geology) separation from a mass, and gathering about centers or into cavities at hand through cohesive attraction or the crystallizing process.3. (genetic) the formation of unique gametes from the genotype of the parents.
What To maintain the chromosome number of an organism the gametes must?
Be produced by meosis.
If an organism had 4 pairs of chromosomes how many different gametes can it produce?
For a species with three pair of chromosomes how many gametic combinations are possible?
What is a diagram that shows possible combinations of gametes?
A punnett square
How many different combinations of maternal and paternal chromosomes can be packaged in gametes made by an organism with a diploid number of 8?
There are about 8 million possibilities for the gametes.
What effect does nondisjunction have on the chromosome number of the gametes?
It gives one of the gametes an extra chromosome and leaves the other gamete with one less chromosome.
What would happen to the possible variation in the gametes if the number of chromosome pairs increased from two to three?
8
Name the 2 human gametes and tell their chromosome number?
The human gametes are Male gametes are sperm and female gametes are eggs. And the gametes chromosome numbers are 42.
The number of possible genetically different gametes for an organism equals 2N, where N is the number of pairs of chromosomes. If an organism has four pairs of chromosomes, how many different gametes can it produce?
16 (apex)
Do somatic cells or gametes have no matched chromosome pairs present?
Gametes only have one of each chromosome, whereas somatic cells have a pair.

What is meant by 'scrambling of allelic combinations?
Recombination, or crossing over, is the exchanging of DNA between homologous chromosomes at meiosis. It results in novel combinations of alleles in the gametes, that is, it scrambles the alleles into new combinations, Let's take an example of an individual that has genes A,B and C on one chromsome, and has the alleles a and c on the other chromosome of the pair: A---B---C a---B---c If crossing over occurs between the genes A and B (and not between B and C), then we can get the following genotypes in the gametes, in addition to the above two combinations: : A---B---c a---B---C Crossing over has scrambled the allelic combinations and given us two new additional ones in the gametes. If we allow recombination between B and C, then even more combinations are possible. One can easily see how recombination can add enormous amounts of genetic variation into a population. Also, note that if no recombination occurs, only the two original combinations of alleles will make it into the gametes.
