What is the chromosome pair for a boy?
A boy has one X chromosome from the mother and one Y chromosome from the father, making his chromosome pair for gender determination XY.
What chromosome pair is not given a number?
The sex chromosomes, X and Y, are not given a number. They determine an individual's sex and are not part of the standard numbered pairs of autosomes.
In humans what are the chromosome pairs 1 through 22 called?
Chromosome pair 23 in humans is the pair of sex chromosomes. In females, both sex chromosomes are the X sex chromosome, and in human males one sex chromosome is the X and the other is the Y chromosome.
How many chromosome and chromosome pairs in humans?
There are 46 chromosomes per cell, with 22 pairs and an XX pair for females or an XY pair for males.
One member of a pair or series of genes that occupies a specific position on a specific chromosome is referred to as?
An allele is one member of a pair or series of genes that occupies a specific position on a specific chromosome. Each allele can encode a specific trait or characteristic. When two alleles are present in an individual, they can interact to determine the physical and physiological traits of that individual.
Why is the number of chromosomes always even?
because every chromosome must have a pair to survive
What is the chromosome pair for a boy?
A boy has one X chromosome from the mother and one Y chromosome from the father, making his chromosome pair for gender determination XY.
Through a microscope you see an exchange of chromosome segments between chromosome pair 7 and chromosome pair 15 This condition is an example?
translocation
What is the chromosome number of gamete?
They have half the number of the somatic (parent) cell. So if a parent cell had 46 chromosomes in its nucleus, then its gamete would have 23(one chromosome from each pair).
What chromosome pair is not given a number?
The sex chromosomes, X and Y, are not given a number. They determine an individual's sex and are not part of the standard numbered pairs of autosomes.
Diploid means what?
Diploid: adj. 1 Double or twofold. 2 Having a homologous pair of chromosomes for each characteristic except sex, the total number of chromosomes being twice that of a gamete.-n 1. a diploid cell. 2. An individual characterized by a diploid chromosome number.It has two copies of each chromosome.
States were chromosomes pair was affected by the Thomsen disease?
Chromosome number 8. (Gene: RECQL4 gene.)
Suppose you're looking through a microscope and you see an exchange of chromosome segments between chromosome pair 7 and chromosome pair 15 this condition is an example of?
the answer is TRANSLOCATION.
What is a pair of chromatin called?
Chromosome
Suppose you're looking through a microscope and you see an exchange of chromosome segments between chromosome pair 7 and chromosome pair 15 this conditions is an example of?
cross over
How many chromosomes are in a homologous pair?
in a homologous chromosome there are two chromosomes ( a chromosome and a sister chromosome)
Suppose your looking through a microscope and you see an exchange of chromosome segments between chromosome pair 7 and chromosome pair 15?
An exchange of chromosome segments is called a translocation. In genetics, it refers to a chromosome abnormality caused by rearrangement of parts between nonhomologous chromosomes.
