What are the characteristic of multiple alleles?
1) Multiple alleles are always on the same location (locus) on the alleles.2)they always effect the same character.3)They always occupy the same gene locus on chromosome.4)no crossing over is known to occur on chromosome.5)a single multiple allelic series affects only one trait _eye color etc
What is a Chromosome complement?
A chromosome complement refers to the total number and types of chromosomes present in an individual's cells. It is specific to each species and can vary among different organisms. This complement plays a crucial role in determining an individual's genetic makeup and characteristics.
What is a X chromosome?
If an individual has the chromosome series XY, that individual would be a male. The Y chromosome is passed down from the father and the X is passed from the mother. The X chromosome contains all hereditary factors while the Y chromosome doesn't contain much genetical information at all, except the fact if Y chromosome is present that individual will be a male. This is all only true for Humans. Dosophilla (fruit flies) have different chromosomal expressions.
What chromosome has to be present for a mother to have a male child?
A mother needs to contribute an X chromosome to her child for them to be male. The father contributes a Y chromosome, resulting in an XY chromosome pair which determines a male child.
What is Unit of inheritance present on the chromosome is called?
The unit of heredity found on a chromosome is called a gene.

Why is the y chromosome useful for tracing ancestry?
The y-chromosome is only present in males. Men will a y-chromosome identical to that of their father, and his father, and his father, etc.

How many chromotids are present in a chromosome at the beginning of mitosis?
2
Is the color blindness gene also present on the Y chromosome?
No - the colour blindness gene is only found on the X chromosome.
What sex chromosome is present in all humans?
There are two sex chromosomes: the X chromosome and the Y chromosome. During fertilization, the mother always gives an X chromosome and the father gives either another X chromosome or a Y chromosome. Therefore, all humans have at least one X chromosome.
What chromosome has to be present for a mother to have a male child?
A mother needs to contribute an X chromosome to her child for them to be male. The father contributes a Y chromosome, resulting in an XY chromosome pair which determines a male child.
What is trisomy syndrome?
In a trisomy syndrome, an extra chromosome is present so that the individual has three of a particular chromosome instead of the normal pair.
What is Unit of inheritance present on the chromosome is called?
The unit of heredity found on a chromosome is called a gene.
How many pairs of chromosome is present in animal cell?
23 pairs
