What is the agent that causes male genitals to differ from female genitals prior to birth?
The presence or absence of the Y chromosome is the key factor that determines whether a fetus will develop male or female genitals. The Y chromosome triggers the production of testosterone in male fetuses, leading to the development of male genitalia. In the absence of the Y chromosome, female genitalia develop by default.
What role does the female sex chromosome play in determining the biological sex of an individual?
The female sex chromosome, known as the X chromosome, plays a crucial role in determining the biological sex of an individual. Females typically have two X chromosomes, while males have one X and one Y chromosome. The presence or absence of the Y chromosome determines whether an individual develops as male or female.
What are the sex chromosomes for a male and how do they determine biological sex?
The sex chromosomes for a male are XY. The presence of a Y chromosome determines male biological sex, while the absence of a Y chromosome results in female biological sex.
In what chromosome is the ear lobe trait located?
The ear lobe trait is not located on a specific chromosome, as it is a common genetic trait that is not influenced by a single gene or located on a specific chromosome. The presence or absence of ear lobes is determined by multiple genetic factors.
What chromosomes typically make up the sex chromosomes in a human male, and how do they determine the individual's biological sex?
The sex chromosomes in a human male typically consist of one X chromosome and one Y chromosome. The presence of a Y chromosome determines the individual's biological sex as male, while the absence of a Y chromosome results in a female biological sex.
What determines the sex of an individual?
Presence or absence of the Y chromosome
Is cystic fibrosis monosmy or trisomy?
Neither. Cystic fibrosis is caused by mutations in the CFTR gene located on chromosome 7. It is not caused by the absence or addition of a chromosome.
What happens to the chromosome during the anaphase?

What determines whether a mammal will be male?
In mammals, the presence or absence of a Y chromosome controls the sex of the individual.
How abnormal number of any chromosome gets into gamete?
That happens in Ana phase.When a chromosome is not split in centromere,a chromosome fully moves to a daughter cell.
What chromosome does tay-sachs disease affect?
Tay-Sachs disease is caused by mutations in the HEXA gene located on chromosome 15. These mutations result in the absence or deficiency of the enzyme hexosaminidase A, leading to the accumulation of harmful substances in the brain and nervous system.
What is the agent that causes male genitals to differ from female genitals prior to birth?
The presence or absence of the Y chromosome is the key factor that determines whether a fetus will develop male or female genitals. The Y chromosome triggers the production of testosterone in male fetuses, leading to the development of male genitalia. In the absence of the Y chromosome, female genitalia develop by default.
Which parents gamete normally determines the sex of the child?
The father's gamete determines the sex of the child. Specifically, the presence or absence of a Y chromosome in the father's sperm will determine if the child will be male (Y chromosome present) or female (no Y chromosome).
What happens to the chromosome of a cell in order for mitosis to begin?
they have to split
Where cystic fibrosis happens?
In the DNA: a mutation on chromosome 7
What chromosome does cystic fibrosis effect?
The gene on chromosome 7 produces a protein called cystic fibrosis trans-membrane regulator. Mutation in the DNA level of chromosome 7 leads to the absence of this protein which leads to cystic fibrosis. Cystic fibrosis is a recessive disease.
What happens due to absence of vitamin d?
Absence of vit d causes rickets in children and osteomalaxia in adult
