Question: How many combinations of 10 chromosomes are there?

How many gamete combinations does 8 chromosomes have?

1. How many different chromosomal combinations can result from meiosis in a species that has a diploid (2N) number of 8? Assume no crossing-over occurs. Sixteen different combinations.

How many combinations are possible with 4 pairs of chromosomes?

In a diploid cell with four chromosomes (two homologous pairs), there are two equally possible ways for the chromosomes inherited from the two parents to be arranged during metaphase I. This variation in the orientation of chromosomes leads to gametes with four equally possible combinations of chromosomes.

How many possible gamete combinations are there for an organism that has a diploid number of 8?

How many possible gamete combinations are there for an organism that has a diploid number of 8? 24 = 2 X 2 X 2 x 2 = 16 different combinations.

How many chromosomes combos are there?

Which chromosome from each of the 23 homologous pairs of both parents is inherited is a matter of chance. There are 8,324,608 possible combinations of 23 chromosome pairs. As a result, two gametes virtually never have exactly the same combination of chromosomes.

What is the chromosome number of Apple?

The modern apple has 17 chromosomes which were found to be derived from an ancestor with 9 chromosomes that experienced genome-wide duplication.

How many gender chromosome combinations are there?

Humans have an additional pair of sex chromosomes for a total of 46 chromosomes. The sex chromosomes are referred to as X and Y, and their combination determines a person’s sex. Typically, human females have two X chromosomes while males possess an XY pairing.

How many possible DNA combinations are there?

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 chromosomes does a human have?

In humans, each cell normally contains 23 pairs of chromosomes, for a total of 46. Twenty-two of these pairs, called autosomes, look the same in both males and females. The 23rd pair, the sex chromosomes, differ between males and females.

What happens to the chromosomes in anaphase I?

During anaphase, each pair of chromosomes is separated into two identical, independent chromosomes. The chromosomes are separated by a structure called the mitotic spindle. … The separated chromosomes are then pulled by the spindle to opposite poles of the cell.

THIS IS IMPORTANT:  Which phase of mitosis are chromosomes 1st seen as a result of chromatin coiling?

What is the main difference between anaphase I and anaphase II?

Anaphase 1 and anaphase 2 are two phases in the meiotic division of cells which produces gametes during the sexual reproduction. The main difference between anaphase 1 and 2 is that homologous chromosomes are separated during anaphase 1 whereas sister chromatids are separated during anaphase 2.

What combination of chromosomes makes up the twenty third pair in a male and a female?

The twenty third pair is called the sex chromosomes, while the rest of the 22 pairs are called autosomes. Typically, biologically male individuals have one X and one Y chromosome (XY) while those who are biologically female have two X chromosomes.

How many possible gamete combinations are there for an organism that has a diploid number of?

Mendel’s second law or the law of segregation describes how alleles are separated during gamete formation. According to this law, one gamete can only have one allele for each gene. For an organism that has a diploid number of 8, there are 16 possible gamete combinations.

How many different combinations of chromosomes are possible in the gametes of the fruit fly?

The number of different combinations of chromosomes that are possible in the gametes is 2n, where n is equal to the number of homologous pairs of chromosomes. For the fruit fly with four pairs of chromosomes, the number of possible combinations is 24 = 16.

How many different combinations of chromosomes can be packaged by in a gamete by an organism with a diploid number of 8 2n 8 )?

The diploid number of chromosomes in a certain animal is 8 (2n = 8). How do the four pairs of homologous chromosomes align and separate during meiosis? They align and assort independently to form any of 16 different combinations.
