What are the sex chromosomes of male human being?
Normal male humans have the sex chromosomes XY. The presence of the Y chromosome determines sex in humans - so a person with XXY will be male.
What is a normal male karyotype?
The male karyotype has 46 chromosomes the same as the female karyotype:23 chromosomes are inherited from your father.
How many chromosomes would be found in a male fruit fly regular body cell?
there is 4 pairs of chromosomes in each cell for a fly!
If a male homozygous for the normal gene order and a female homozygous for an inversion mutation had a child the child would have what type or types of chromosomes?
The child would inherit one set of chromosomes from each parent. Since the male is homozygous for the normal gene order, he will pass on a normal chromosome set. The female, being homozygous for the inversion mutation, will pass on chromosomes that carry the inversion. As a result, the child will have one set of normal chromosomes and one set with the inversion mutation, leading to a genotype that is heterozygous for the inversion.
How many chromosomes does a male grasshopper have?
A male grasshopper typically has 23 pairs of chromosomes, for a total of 46 chromosomes.
What pair of chromosomes is not homologous in a normal male karyotype?
The pair of sex chromosomes (X and Y) is not homologous in a normal male karyotype. Males have one X and one Y chromosome, while females have two X chromosomes.
What are the sex chromosomes of male human being?

The cells of a human male have which composition for their sex chromosomes?
A normal male will have one X and one Y chromosome.

What combination of chromosomes is a female an a male?
Normal females have XX chromosomes and normal males have XY chromosomes. I believe there are two of each in a human body and the rest are autosomes.
How many chromosomes are there in sex cells and why?
22 pair of autosomes and 1 pair of sex chromosomes. A male determines the sex with XY chromosomes and the female only has YY. 23; half of the normal 46 for a cell. This is so when the male and female cells meet, they will form a normal 46-chromosome cell.
What is the male genotype?
Maleness is not a genotype but a combination of sex chromosomes. A normal human male has an X as well as a Y chromosome.
What is the sex chromosomes of male?
In humans and other mammals, a male has XY sex chromosomes. In birds, a male has XX chromosomes. In amphibians, male chromosomes look the same as female chromosomes.
Name one pair of chromosomes not homologous in a normal karyotype?
Sex chromosomes X and Y are not homologous in a normal karyotype. This pair of chromosomes determines an individual's biological sex, with females having two X chromosomes and males having one X and one Y chromosome.
If a male homozygous for the normal gene order and a female homozygous for an inversion mutation had a child the child would have what type or types of chromosomes?
The child would inherit one set of chromosomes from each parent. Since the male is homozygous for the normal gene order, he will pass on a normal chromosome set. The female, being homozygous for the inversion mutation, will pass on chromosomes that carry the inversion. As a result, the child will have one set of normal chromosomes and one set with the inversion mutation, leading to a genotype that is heterozygous for the inversion.
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.
