No, an organism's genetically expressed characteristics, or phenotype, may be altered or affected by its environment; in a purely physical connotation, Nature versus Nurture.
There are dozens of Cell types yet we are told that all Cells contain the same set of Genes; how can this be?
An organism is composed from organs. The characteristics of an organ are determined by the Expression of the genes that are ensconced in its Nucleus.
It is highly common that many 'gene products' act as biochemical switches that by their presence, or absence, determine {called determination} wether or not another gene will be 'actively' expressed. This would be 'internal regulation'.
The NEW SCIENCE OF EPIGENETICS focuses on the external or environmental molecular switches that effect (the) patterns of gene expression.

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.
What is halfloid genes?
Halfloid genes refer to a situation where an organism carries only one set of chromosomes instead of the usual two sets (diploid). This can occur in certain haploid organisms or as a result of a mutation leading to the loss of one set of chromosomes. Halfloid organisms may exhibit unique genetic characteristics and reproductive strategies compared to diploid organisms.
Does a cell have only a few genes?
No, a cell can have thousands of genes. Genes contain the instructions for making proteins that carry out various functions within a cell. The interactions of these genes determine the cell's characteristics and behaviors.
Are all characteristics controlled by only 1 gene?
No, characteristics can be controlled by multiple genes interacting with each other. This is known as polygenic inheritance. Additionally, environmental factors can also influence the expression of these genes, further complicating the determination of specific genetic control.
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.
Are person's characteritsics determined only by genes?
physical characteristics, yes. unless there was a mutation at birth
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.
Is a persons height determined by genes only?
No. Height can also be determined by environmental factors such as diet.
Are a person characteristic determined only by genes?
No- some are determined by environment. If you are tanned, have callouses on your hands, have strong arms and a 6 pack abs- that came only partially from your genes. Exposure to sunlight and hard labor got you the rest.
What is halfloid genes?
Halfloid genes refer to a situation where an organism carries only one set of chromosomes instead of the usual two sets (diploid). This can occur in certain haploid organisms or as a result of a mutation leading to the loss of one set of chromosomes. Halfloid organisms may exhibit unique genetic characteristics and reproductive strategies compared to diploid organisms.
Do male dogs get the genes of their father when born?
They get the genes of both parents. Only one chromosome determines gender, but the rest of the traits are determined by both parents.
Is it true that the only thing determined by the genes carried on sex chromosome is a person gender?
No, the genes carried on sex chromosomes determine more than just a person's gender. They also play a role in other biological traits, such as physical characteristics, hormone production, and some disease risks.
Does your inherit characteristics from your mother only?
No, you inherit characteristics from both your mother and your father. Genes from both parents contribute to your physical and behavioral traits.
Are genes found only in animals?
No, genes are found in all living organisms, including animals, plants, bacteria, and fungi. Genes are units of heredity that contain instructions for building and maintaining an organism.
Does a cell have only a few genes?
No, a cell can have thousands of genes. Genes contain the instructions for making proteins that carry out various functions within a cell. The interactions of these genes determine the cell's characteristics and behaviors.
What are three characteristics of a cladistic analysis?
cladistic analysis identifies and considers only those charateristics of organisms that are evolutionary innovations cladistic analysis identifies and considers only those charateristics of organisms that are evolutionary innovations
Are persons characteristics determined only by genes?
No, a person's characteristics are partly genetic and partly acquired; biologists refer to this as nature and nurture. For example, the fact that I speak English is not a genetic trait. I speak English because that is the language that my parents taught me to speak. The fact that I was capable of learning to speak English is genetic.
