How many chromosomes are in a typical body?
Human beings normally have 46 chromosomes (in the form of 23 pairs).
The human X and Y Chromosomes are what?
The human X and Y chromosomes are:both present in every somatic cell of males and females.approximately equal in size.almost entirely homologous, despite their different names.called "sex chromosomes" because they determine an individual's sex.
How do chromosomes determine sex?
In Human Beings two chromosomes normally determine a persons sex. If a person has two X chromosomes, (XX), that person will be a female. If a person has an X and a Y chromosome, that person will be a male. Most people get 23 chromosomes from their mother and 23 from their father. Thus, most people have 46 chromosomes. They get either an X or a Y chromosome from their father. Sometimes things get complicated. That is for another answer.
How number of chromosomes in a cells compare to the number in its sex cells?
The human cell has 46 chromosomes. In the sex cell of a human it has one half that many. So 23 chromosomes from each parent. Different species have different number of chromosomes. This is why you do not have mixes such as a centaur.
How many chromosomes are in one human cell?
46 single chromosomes which is 23 pairs of chromosomes in one human body cell.
Sex in human beings is determined by?
Chromosomes
How many chromosomes are in a typical body?

Why do genetics perform karyotype?
Most Probably because for studying the chromosomes. Determining the structure of chromosomes, number of chromosomes, haplontic or diplontic nature, and most importantly to determine the genetic diseases like Down's syndrome in which the chromosome number is 47 while the normal human beings have 46 chromosomes i.e. 23 pairs.
The human X and Y Chromosomes are what?
The human X and Y chromosomes are:both present in every somatic cell of males and females.approximately equal in size.almost entirely homologous, despite their different names.called "sex chromosomes" because they determine an individual's sex.
What word means carry genes that determine the sex of offspring?
the answer is DNA chromosomes.
A photograph of human chromosomes that may be studied to determine possible genetic disorders is known as?
a karyotype
How many chromosomes are in each daughter cell in mitosis?
in case of human beings each daughter cell gets 23pairs of chromosomes means each get a total of 46 chromosome after karyokinesis.

What is one and vocation that all human beings share?
One common vocation shared by all human beings is the pursuit of happiness and fulfillment. This can manifest differently for each individual, but ultimately, we all seek to lead meaningful and satisfying lives.
Which molecules coded by genes on chromosomes determine cell structure and function?
Genes copied from DNA are copied to RNA in a process called transcription. The RNA transcripts are then used in a process called translation, in which a code that determine the sequence of amino acids is translated to form a protein. The structure of the resulting protein determines the role of the protein in body structure and function...and ultimately, the structure and function of the body.
What is the term for chromosomes that do not determine sex?
Chromosomes that aren't sex chromosomes are called autosomes. There are 44 autosomes in a normal human somatic cell and 22 in normal human gametes. The only chromosomes that affect the sex of an organism is the X and/or Y chromosome. XX = Female and XY = Male.
