How many gametes are possible?

How do you calculate the number of possible combinations of a chromosome?

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. For a human, n = 23, so there are 223, or about 8 million, possible chromosome combinations!

How many unique gametes are produced?

The correct answer is (b) 8. In this scenario, each gamete will consist of five genes.

How many DNA combinations are possible?

In a tetranucleotide block where the nucleotides can appear more than once and the order is random, there can be 256 possible combinations. 256 is a large number of possible DNA letters.

How many different combinations are possible for these chromosomes in the haploid cells formed by meiosis?

When these chromosome pairs are reshuffled through independent assortment, they can produce eight possible combinations in the resulting gametes: A B C. A B c.

How many different combinations of maternal and paternal chromosomes are possible for the gametes?

Maternal and paternal chromosomes are randomly distributed on either side of the metaphase plate. So for each pair there’s a 50/50 chance as to which side the homologs will go on (8.17). We have 23 pairs each with 50/50 probabilities. That works out to 223 possible combinations of gametes from one human individual.

How do you find the number of gametes from genotype?

To calculate the total number of gametes that are produced by a particular genotype, a specific formula 2n is used, where n= number of heterogeneous alleles that are found in the genotype. Here, the given genotype consists of two heterogeneous alleles Bb, and Cc while one homozygous allele is AA.

What are gametes example?

In short a gamete is an egg cell (female gamete) or a sperm (male gamete). … This is an example of anisogamy or heterogamy, the condition in which females and males produce gametes of different sizes (this is the case in humans; the human ovum has approximately 100,000 times the volume of a single human sperm cell).
