Q: How to get all possible combinations of gametes for diploids and polyploids, including those that are the result of nondisjunction of chromosomes? A: To do this, you need each group of chromosomes (genes) in the parental genotype entry conclude in ampersands characters, like this.

How many different combinations of people are possible? I suppose it should be the number of genes multiplied by the number of alleles per gene, is that correct? -A curious adult from Israel. October 24, 2012. The short answer is probably close to an infinite number of combinations. Let’s put our math thinking caps on and see how we can chop and dice this problem and arrive at a number.If you need to generate all possible combinations based on multiple columns data, maybe, there is not a good way of dealing with the task. But, Kutools for Excel's List All Combinations utility can help you to list all possible combinations quickly and easily. Click to download Kutools for Excel! Kutools for Excel: with more than 300 handy Excel add-ins, free to try with no limitation in 30.With over 64 million combinations (from combined sperm and egg) just one of those haploid cells from the mom will be fertilized by the dad's haploid cells Karyotype display of an individual's condensed chromosome pairs.
Understanding this fact will be important when you actually calculate a linkage distance estimate from your data. The important question is how many recombinant chromosomes will be produced. If the genes are far apart on the chromosome a cross over will occur every time that pairing occurs and an equal number of parental and recombinant chromosomes will be produced. Test cross data will then.Read More
Haplotype resolution. An organism's genotype may not define its haplotype uniquely. For example, consider a diploid organism and two bi-allelic loci (such as SNPs) on the same chromosome.Assume the first locus has alleles A or T and the second locus G or C.Both loci, then, have three possible genotypes: (AA, AT, and TT) and (GG, GC, and CC), respectively. For a given individual, there are.Read More
It is possible to isolate the rare cells in which the F factor is integrated into the host chromosome from the bacterial population and to cultivate pure strains derived from these cells. In such strains, every cell donates chromosomal alleles during F transfer, so the frequency of recombinants for these strains is much higher than it is for cells in the original population, where the F factor.Read More
Therefore, you must place one member of each gene pair into a gamete. The possible combinations of r's and t's are--RT, Rt, rT, rt. Those are the four possible gametes this individual can produce.Read More
To create a Punnett square, write all the possible alleles across the top of the square for one parent and all the possible alleles for the other parent down the left-hand side. Each listed allele will become either a column, for top alleles, or a row, for left-side alleles, inside the square. The square is filled in as you write down alleles from the top in their respective columns and then.Read More

How many chromosome combinations are possible in the haploid gametes of an organism with a diploid number of 6? When the chromosome pairs separate during the creation of the haploid, for each of.Read More
The father stores a single set of his chromosomes in each sperm, some will have the X chromosome and some will have the Y.The mother has a single set of her chromosomes in each of her eggs and as women have two X chromosomes, all her eggs will have the X chromosome. Since the sperm and egg sex cells only contain one set of chromosomes, they are called haploid sex cells.Read More
A monohybrid cross involves the crossing of individuals and the examination of a single character (flower color (Figure 1) OR seed color OR pod shape, etc.) in their offspring. The Punnett square is a useful tool for predicting the genotypes and phenotypes of offspring in a genetic cross involving Mendelian traits. Constructing a Punnett square is quite easy, as shown in the Web sites below.Read More
However this is a really time-consuming thing to do in an exam and errors can easily be made. By looking at the original genotype, in the case of the example BBRRSS, I can see there are three genes, each with 2 alleles. Is there then a quick and easy way of working out that the number of gamete combinations is 8 without listing them all? Thank you!Read More
