How many types of zygotic combinations are possible between a cross Aa BB Cc Dd x AA bb Cc DD? The number of possible gamates = 2n, where n is number of heterozygous pairs of genes. When 8 combinations are crossed with 2 combination, the number of zygotic combinations = 8 x 2 = 16.

In this example, there are four possible genetic combinations for the gametes. With n = 23 in human cells, there are over 8 million possible combinations of paternal and maternal chromosomes.

There are two possibilities for orientation at the metaphase plate; the possible number of alignments therefore equals 2n, where n is the number of chromosomes per set. Humans have 23 chromosome pairs, which results in over eight million (223) possible genetically-distinct gametes.

Types of Quintuplets Polyzygotic quintuplets occur from five unique egg/sperm combinations whereas monozygotic multiples are the result of one fertilized egg that splits into two or more embryos.

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.

During sexual reproduction, fertilization of the ovum (n, 23 chromosomes) by the sperm (n, 23 chromosomes) restores the diploid number and creates a zygote (2n, 46) (awww..) that divides and grows by mitosis to form a multicellular human.

In humans, over 8 million (223) chromosome combinations exist in the production of gametes in both the male and female. A sperm cell, with over 8 million chromosome combinations, fertilizes an egg cell, which also has over 8 million chromosome combinations.

Answer: (a) Ovary - Diploid, (b) Anther - Diploid, (c) Egg - Haploid, (d) Pollen - Haploid, (e) Male gamete - Haploid, (f) Zygote - Diploid.

In the name "Dihybrid cross", the "di" indicates that there are two traits involved (e.g. R and Y), the "hybrid" means that each trait has two different alleles (e.g. R and r, or Y and y), and "cross" means that there are two individuals (usually a mother and father) who are combining or "crossing" their genetic ...

For a human, n = 23, so there are 223, or about 8 million, possible chromosome combinations! The number of different chromosome combinations in gametes is one factor that contributes to genetic variation.

With n = 23 in human cells, there are over 8 million possible combinations of paternal and maternal chromosomes. (CC BY 4.0 via OpenStax College). In humans, there are over 8 million configurations in which the chromosomes can line up during metaphase I of meiosis.

The zygote is diploid, with two sets of chromosomes, one from each parent. A human zygote has two sets of 23 chromosomes, for a total of 46 chromosomes (23 pairs).

3. Random fertilization: The ovum has 8 million possible chromosome combinations, so does the sperm cell. 8 million x 8 million = 64 trillion possible diploid combinations in EACH AND EVERY zygote!

14. 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).
