What is karyotype?
A method of illustrating what chromosomes are present.
How many gene is present in one chromosomes?
A given gene is present on exactly two chromosomes in a somatic cell.
How many chromosomes are present when meiosis is started?
In humans, 46 chromosomes are present when meiosis begins. The four daughter cells that result from meiosis have 23 chromosomes.
Which structure present in the nuclear region of a living cell bear genes?
The structure present in the nuclear region of a living cell that bears genes is the nucleus. Within the nucleus, genes are located on long strands of DNA called chromosomes. These chromosomes contain the genetic information necessary for the cell's functioning and development.
If both members of a pair of chromosomes are present in the cell the condition of the chromosomes is said to be?
If both members of a pair of chromosomes are present in the cell, the condition of the chromosomes is said to be diploid. Diploid cells have two sets of chromosomes, one set derived from each parent.
How many sets of human chromosomes are present in a spermatid?
23 chromosomes are present in spermatids
Which sex chromosomes are present in females?

Where are chromosomes present in a cell?
Chromosomes are seen in the nucleus of the eukaryotic cells.
How many gene is present in one chromosomes?
A given gene is present on exactly two chromosomes in a somatic cell.
How many chromosomes are present when meiosis is started?
In humans, 46 chromosomes are present when meiosis begins. The four daughter cells that result from meiosis have 23 chromosomes.
What structures contain the genes for the traits?
Genes for traits are contained within the chromosomes, which are found in the cell's nucleus. Each gene is a segment of DNA that encodes a specific trait or characteristic. Genes are passed down from parents to offspring during reproduction.
Which structure present in the nuclear region of a living cell bear genes?
The structure present in the nuclear region of a living cell that bears genes is the nucleus. Within the nucleus, genes are located on long strands of DNA called chromosomes. These chromosomes contain the genetic information necessary for the cell's functioning and development.
Are chromosomes presents when the cell is dividing?
yes chromosomes are present when cell divide
What is an example of a disorder associated with an error in the number of chromosomes present?
One example of a disorder associated with an error in the number of chromosomes present is Down syndrome. This disorder is caused by the presence of an extra copy of chromosome 21, leading to characteristic physical features and often intellectual disability.
