A body has 48 chromosomes, which are paired into 23 pairs. The 23rd, known as the the xy chromosomes, are also called the sex chromosomes. They determine whether you are a boy or a girl. Females have two chromosomes, xx, and boys have one x and one y chromosome. The y chromosome is kindof a deformity, an x missing a pice. y chromosomes cannot carry genetic information, so the x carries the traits for sexual development. one x or y is given y each parent. The mother always gives an x, the father can give x or y, thus being the determining factor for gender
What else can I help you with?
An epigenetic effect that influences the sex of a child is the?
methylation pattern of genes involved in sex determination during early development. This can affect the expression of key genes, leading to the development of male or 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.
Are genes transmitted only during sexual reproduction?
Genes can be transmitted during both sexual and asexual reproduction. During sexual reproduction, genes are combined from two parents to produce offspring with a mix of traits. Asexual reproduction can involve the direct transmission of genes from a single parent to offspring through processes like cell division.
What do gap genes do?
Gap genes are a class of genes that play a crucial role in early embryonic development, particularly in the segmentation process of organisms such as Drosophila (fruit flies). They are responsible for establishing the primary body plan by defining broad regions of the embryo along the anterior-posterior axis. Gap genes are activated by the maternal effect genes and, in turn, regulate the expression of pair-rule and segment polarity genes, which further refine the segmentation pattern. Overall, gap genes help ensure proper spatial organization and differentiation of body segments during development.
The hox genes are a series of genes that control?
The hox genes are a series of genes that control the body plan of an organism during development. They help determine the placement and structure of body parts along the anterior-posterior axis. Mutations in hox genes can lead to developmental abnormalities.
An epigenetic effect that influences the sex of a child is the?
methylation pattern of genes involved in sex determination during early development. This can affect the expression of key genes, leading to the development of male or female sexual 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.
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 controlled human growth and sexual development?
Human growth and sexual development are primarily controlled by the endocrine system, specifically by hormones such as growth hormone, testosterone, and estrogen. These hormones regulate processes like cell division, tissue growth, and the development of secondary sexual characteristics. Genes also play a significant role in determining the timing and rate of growth and development.
Are genes transmitted only during sexual reproduction?
Genes can be transmitted during both sexual and asexual reproduction. During sexual reproduction, genes are combined from two parents to produce offspring with a mix of traits. Asexual reproduction can involve the direct transmission of genes from a single parent to offspring through processes like cell division.
What genes can a trait be determined by?
Sexual and Asexual
What role do sex-limited genes play in determining specific traits or characteristics in organisms?
Sex-limited genes are genes that are only expressed in one sex, leading to the development of specific traits or characteristics unique to that sex. These genes play a crucial role in determining gender-specific features, such as reproductive organs or secondary sexual characteristics, in organisms.
The benefits of sexual repouduction for cats?
They get to pass on their genes.
How sexual reproduction produce in indentical offspring?
its in the genes
Where do the offspring of sexual reproduction get its genes from?
The mother and father
How do genes and chromosomes effect your development?
Chromosomes are genes you get from your parents. They affect your physical features and how you grow. Like if your parents were both short, you would get chromosomes deciding if you get their dominate gene (short) or both recessive genes (tall). You have 42 chromosomes when you are born (21 from each parent)
