Sexual characteristics are primarily controlled by the X and Y chromosomes, which determine an individual's sex. In humans, individuals with two X chromosomes (XX) typically develop female characteristics, while those with one X and one Y chromosome (XY) typically develop male characteristics. The presence of the SRY gene located on the Y chromosome plays a critical role in initiating male sex determination.
What else can I help you with?
Which of these statements is true biology aplus?
only some genes located on the X chromosome control female sexual characteristics
For what are genes on the y chromosome responsible?
Genes on the Y chromosome are responsible for male sex determination and other male-specific traits. They play a crucial role in the development of male reproductive organs and secondary sexual characteristics.
What is the chromosome that dictate most body characteristics?
The chromosome that dictates most body characteristics is chromosome 1. It is the largest chromosome in humans and carries a significant amount of genetic information related to various traits and functions in the body.
What is the y chromosome?
only men have them
Is a chromosome a allele?
No, a chromosome is a structure that contains genetic information, while an allele is a specific variant of a gene located on a chromosome. Chromosomes contain many alleles that determine an individual's traits and characteristics.
Do only some of the genes located on the X chromosome control female sexual characteristics?
Yes, not all genes located on the X chromosome control female sexual characteristics. The SRY gene on the Y chromosome is responsible for male sexual development. However, genes on the X chromosome like the XIST gene are involved in the regulation of X chromosome inactivation, a process critical for normal development in females.
What determines a person's sex during development?
well a persons sex is determined at conception the thing that determines it is the thirty second chromosome whick is provided by a male it can be an X chromosome or a Y chromosome if it is an X the formula is XX (because the women has an X chromosome) and it is a guy if it is XY
Which of these statements is true biology aplus?
only some genes located on the X chromosome control female sexual characteristics
What part of a chromosome carries information and controls a trait?
Genes, which are segments of DNA, carry the information that controls traits on a chromosome. Each gene contains the instructions for making specific proteins that determine various characteristics or traits in an organism.
Which chromosome carries a gene which is essential for maleness?
The Y chromosome carries the SRY gene (Sex-determining Region Y) which is essential for male sexual development. The SRY gene triggers the development of male sex characteristics during fetal development.
How do boys chromosomes differ from girls?
Boys have one x chromosome and a y chromosome, whereas a girl has two x chromosomes.
What gland controls testosterone?
In a nutshell controls man features during purberty such as body hair or penis size and even height
For what are genes on the y chromosome responsible?
Genes on the Y chromosome are responsible for male sex determination and other male-specific traits. They play a crucial role in the development of male reproductive organs and secondary sexual characteristics.
What is the chromosome that dictate most body characteristics?
The chromosome that dictates most body characteristics is chromosome 1. It is the largest chromosome in humans and carries a significant amount of genetic information related to various traits and functions in the body.
What controls most but not all activities in the cell?
nucleus not chromosome
In humans a male has?
One X chromosome and one Y chromosome, which determines male sex characteristics.
What role do sex chromosomes play in determining the biological sex of humans?
Sex chromosomes play a crucial role in determining the biological sex of humans. Typically, females have two X chromosomes (XX) and males have one X and one Y chromosome (XY). The presence of the Y chromosome triggers the development of male characteristics, while the absence of the Y chromosome results in the development of female characteristics. This genetic combination influences the development of reproductive organs and secondary sexual characteristics in humans.
