How many genetically different gametes can this cell form?

How many genetically different gametes can this cell form?

The number of different possible gametes produced by the diploid genotype (AaBbCcDdEe) is 2 x 2 x 2 x 2 x 2 = 32 (2 for each pair of heterozygous genes).

What is the number of possible gametes that can be formed due to independent assortment of chromosomes?

32. Since humans have 46 chromosomes or 23 homologous pairs, what is the number of possible gametes that can be formed due to independent assortment of chromosomes? The number of possible combinations of maternal and paternal chromosomes in the resulting gametes is 223, or about 8.4 million.

How many genetically different kinds of gametes an individual with genotype AaBb can produce?

four possible combinations
There are four possible combinations of gametes for the AaBb parent. Half of the gametes get a dominant A and a dominant B allele; the other half of the gametes get a recessive a and a recessive b allele. Both parents produce 25% each of AB, Ab, aB, and ab.

How many possible genetic combinations can arise from meiosis?

= 256 different combinations.

What increases the number of genetically unique gametes an organism can produce?

Genetic variation is increased by meiosis Because of recombination and independent assortment in meiosis, each gamete contains a different set of DNA. This produces a unique combination of genes in the resulting zygote. Recombination or crossing over occurs during prophase I.

How do you know how many gametes can be formed?

Simply place a 2 above each heterozygous gene pair and a one above each homozygous gene pair. Then multiply the numbers together to obtain the total number of different possible gametes.

How do you find the possible gametes?

When you are doing a monohybrid cross, finding possible gametes is easy. All you have to do is give one allele to half the gametes, and the other allele to the other half of the gametes (remember gametes are haploid, so they get only 1 of each gene or letter!). Then cross out any duplicates.

How do you calculate the number of possible chromosome combinations?

If you know the haploid number for an organism, you can calculate the number of possible combinations in the gametes. The possible combinations are equal to 2n, where n is the haploid number. For the organism in Figure 9-18, n = 2, so the number of chromosome combinations is 22, or 4.

How does meiosis lead to increased genetic variation?

How to find the possible combinations of gametes?

How do you find the possible combinations of gametes? If you know the haploid number for an organism, you can calculate the number of possible combinations in the gametes. The possible combinations are equal to 2 n, where n is the haploid number. For the organism in Figure 9-18, n = 2, so the number of chromosome combinations is 2 2, or 4.

How many chromosomes are there in a gamete?

How many chromosomes do gametes have? In humans, gametes are haploid cells that contain 23 chromosomes, each of which a one of a chromosome pair that exists in diplod cells. The number of chromosomes in a single set is represented as n, which is also called the haploid number.

How many different gametes can be produced from a diploid?

In determining the number of gametes that can be produced from a particular diploid genotype, it is generally computed as 2 n, with n being the number of genes involved in the process. The genotype AaBbCCddEEFF shows that there are 6 genes available for distribution. Therefore, the answer is B. 4.

How can you make more than one haploid gamete?

All you have to do is give one allele to half the gametes, and the other allele to the other half of the gametes (remember gametes are haploid, so they get only 1 of each gene or letter!). Then cross out any duplicates. Are gametes haploid or diploid?
