- A trait is a specific characteristic of an organism. Traits can be determined by genes or the environment, or more commonly by interactions between them. The genetic contribution to a trait is called the genotype. The outward expression of the genotype is called the phenotype.

- A gene is a sequence of DNA that determines a particular trait. A chromosome is a coiled DNA chromosome that contains the organisms genetic code (aka-genes). chromosome is a long packaged DNA sequence. The human diploid (DNA From both mother and father) cell has 46 of these. A chromosome contains thousands of genes which are the … sequences in the actual DNA that code for end products such as proteins.

- The combination of genes expresses itself in the traits of a person. There are 23 pairs of chromosomes in a single cell of a fertilized egg. On each pair of chromosomes, two genes -- one that is dominant and one that is recessive -- are present. The combination determines the trait of a person.

Trait Trait is a specific characteristic of an individual. For example, their hair color or their blood type. Traits are determined by genes, and also they are determined by the interaction with the environment with genes.

Genes and Genetic Inheritance Genes exist in alternative forms called alleles. Alleles determine distinct traits that can be passed on from parents to offspring. The process by which genes are transmitted was discovered by Gregor Mendel and formulated in what is known as Mendel's law of segregation.lleles determine distinct traits that can be passed on from parents to offspring.

Human Physiology/Genetics and inheritance Polygenic traits are traits determined by the combined effect of more than one pair of genes. Human stature is an example of this trait. The size of all body parts from head to foot combined determines height. The size of each individual body part are determined by numerous genes.

How Are a Baby's Inherited Traits Determined? Genes from both parents are responsible for a baby’s inherited traits. Genes are located in your cells’ chromosomes which are at the center of every cell in the body. The genes within your cells determine your traits as well as the way your body functions.

- A trait is any gene-determined characteristic. Many traits are determined by the function of more than one gene. For example, a person's height is likely to be determined by genes affecting growth, appetite, muscle mass, and activity level.very human cell contains 23 pairs of chromosomes, for a total of 46 chromosomes. A trait is any gene-determined characteristic and is often determined by more than one gene. Some traits are caused by abnormal genes that are inherited or that are the result of a new mutation.

How Are a Baby's Inherited Traits Determined? A baby’s genes are determined upon conception. However, some factors can alter these genes before a baby is born, and can harm a fetus before birth. Your baby inherits normal traits but can also inherit abnormal traits. Such genes are referred to as single gene defects, which can cause birth defects.

Common Misconceptions 1. Genes are the sole determinants of traits. Genes are typically not the only determinants of traits. Although a few traits, such as blood type, are determined strictly by genetics, most traits are influenced both by genes and the environment in which we live. We do not inherit a disease, instead we inherit susceptibility factors that increase risk for a disease.

Inheritance of Traits by Offspring Follows Predictable Rules Somatic cells contain two alleles for every gene, with one allele provided by each parent of an organism. Often, it is impossible to determine which two alleles of a gene are present within an organism's chromosomes based solely on the outward appearance of that organism.owever, an allele that is hidden, or not expressed by an organism, can still be passed on to that organism's offspring and expressed in a later generation. Figure 1: In this family pedigree, black squares indicate the presence of a particular trait in a male, and white squares represent males without the trait.

- Genetic traits are carried on chromosomes, which are long molecules of a nucleic acid called DNA. Each chromosome carries the genetic code for many different traits. Each trait is at a different location on the chromosome. We call these traits genes.

- A gene is a heritable factor that controls a specific characteristic of an organism. An allele is one specific form of the gene, differing from other genes by one or a few bases only and occupying the same gene locus as other alleles of the same gene.

What Is an Inherited Trait? Top 10 unbelievable historical concurrencies. An inherited trait is any element of an organism's makeup passed down to it by one or both of its parents. For instance, eye color is an inherited trait, with the eye color of the parents affecting the eye color of the child.Inherited traits are passed from parent to offspring by genetic transmission, in which the child receives some of its genes from each parent.Physical traits are the expression of genes, which determine how the body forms. A specific instance of a particular gene is called an allele.op 10 unbelievable historical concurrencies.

Allele Jump to navigation. An allele is a different form of a gene that is located in a specific place on a chromosome that controls a specific trait and is responsible for genetic variation.herefore, an allele is one of a pair of alleles. Hair color is decided by alleles (sequence variations) of the gene that controls hair color. One allele might possess the trait for blond hair and another allele that of black hair.
