Which Of the combination of sex chromosomes is found in a normal human female?
The normal monoploid (n) # of a female sex cell is 23 chromosomes
In humans the number of tetrads formed during mitosis is?
A tetrad is the pairing of homologous chromosomes. A human offspring inherits 23 chromosomes (N) from each parent upon fertilization, giving the offspring 46 chromosomes (2N). In meiosis, homologous chromosomes (N from mom and N from dad) come together and form a tetrad, which consists of 2 homologous chromosomes. Since you inherit a chromosome from both parents (2N) that pair up to form a tetrad, you will have 23 tetrads that have a chromosome from mom and dad paired together. 1 N from mom + 1 N from dad = homologous pair = 1 tetrad 2N/2 = N tetrad --humans--> 2(23 chromosomes)/2 = 23 tetrads Diploid#/2 = # tetrad
What are n chromosomes?
N chromosomes refers to the total number of chromosomes in a cell. In humans, n typically equals 23, consisting of 22 pairs of autosomes and 1 pair of sex chromosomes (XX for females, XY for males). Each parent contributes one set of 23 chromosomes to their offspring, resulting in a total of 46 chromosomes.
How many chromosome are in a egg?
Eggs and sperms are gametes. They are haploid. Haploid means that they have half the regular number of chromosomes. This works really well because an egg and a sperm join together to begin a new organism which will then have the entire diploid number of chromosomes. A human body cell would have 46 chromosomes. Since a human egg cell is a reproductive cell (sex cell), it would contain only half the number of chromosomes as a body cell. Thus, a human egg cell would have 23 chromosomes. A sex cell has half the number of chromosomes for a good reason. When two sex cells reproduce, they combine to form double the number of chromosomes. So when two cells with 23 chromosomes each reproduce, the offspring would have 46 chromosomes. To keep humans at 46 chromosomes per cell, sex cells are produced through meiosis, which is a process that creates cells with half the number of chromosomes.
How many chromosomes are in 50 sperm cells?
I assume you mean human sperm cells.Haploid and n = 23 chromosomes, so......23 * 50= 1150 chromosomes===============
How many chromosomes does a sex cell have?
a human, gametes have 23. half the number of other cells
How many chromosomes are in a sperm Cell?

How many chromosomes are contained in a human male gamete cell?
In a gamete (sex) cell, there are 23 chromosomes. A gamete is a haploid, or n, whereas a somatic (normal) cell is a diploid, or 2n, and has 46 chromosomes.
Normal human gametes carry how many chromosomes?
Normal human gametes carry 23 chromosomes, which is half the number of chromosomes found in a somatic cell. During fertilization, a sperm cell with 23 chromosomes fuses with an egg cell, also with 23 chromosomes, to form a zygote with a total of 46 chromosomes.
Which Of the combination of sex chromosomes is found in a normal human female?
The normal monoploid (n) # of a female sex cell is 23 chromosomes
What is the difference on diploid and haploid cells?
Diploid and haploid are terms used to describe how many chromosomes are in a cell. Haploid or "n" represents half and Diploid or "2n" represents 2 times the n amount. For examples, in human haploid is n=23 chromosomes while diploid is 2n or 2(23) or total of 46 chromosomes.
Number of chromosomes in eggs and sperm cells?
I assume you mean human egg and sperm cells. There is a haploid number of chromosomes in these cells. 23 chromosomes. n.
How many pair of chromosomes do normal human cells contain?
Gametic [haploid] Cells are chromosome number n - which involves 23 individual chromosomes. Somatic [or diploid] Cells are chromosome number 2n - which involves 23 pairs of chromosomes. Mitotic Cells are 4n.
In humans the number of tetrads formed during mitosis is?

In meiosis, homologous chromosomes (N from mom and N from dad) come together and form a tetrad, which consists of 2 homologous chromosomes. Since you inherit a chromosome from both parents (2N) that pair up to form a tetrad, you will have 23 tetrads that have a chromosome from mom and dad paired together. 1 N from mom + 1 N from dad = homologous pair = 1 tetrad 2N/2 = N tetrad --humans--> 2(23 chromosomes)/2 = 23 tetrads Diploid#/2 = # tetrad
How many chromosomes are there in a goat's diploid cell?
will assume that you mean human cells. Somatic cells are diploid (2n), containing two sets of chromosomes, one of paternal, one of maternal origin. Gametes, on the other hand, are haploid (n), with a single set of chromosomes, ie. half as many as the somatic cell. Now, the haploid chromosome number (n) is characteristic of the species, and in humans this number happens to be 23. Therefore a human gamete has 23 chromosomes, and a human somatic cell 23 pairs, or 46 chromosomes.
How many chromosomes does a human haploid cell have?
The haploid number is the number of chromosomes within the nucleus of a cell that constitutes one complete chromosomal set. This number is commonly abbreviated as n, where n stands for the number of chromosomes. The haploid number will be different for different organisms. In humans, the haploid number is expressed as n=23.Haploid human cells have 1 set of 23 chromosomes:Autosomal chromosomes (non-sex chromosomes): 22 sets.Sex chromosomes: 1 set.Diploid human cells have 2 sets of 23 chromosomes for a total of 46 chromosomes:Autosomal chromosomes: 22 sets of 2.Sex chromosomes: 1 set of 2.
