Why is it that a person with an allele for a particular trait may not have a phenotype that shows the trait?
a dominant allele will express its trait , as well as be carried by the person. the word carrier is commonly used for a person who bears an allele which does not express itself(i.e. a recessive gene).
What is polygeny?
Inheritance in which more than one gene pair affects the appearance of a particular trait. Polygenetic inheritance refers to the non-Mendelian form of inheritance in which a particular trait is produced by the interaction of many genes.
State the conclusions reached by mendel in his work on the inheritance of characteristics?
- Some "alleles" (hereditary traits) are dominant, and others are recessive. - If a pure dominant trait is bred with a recessive trait, their offspring will show 75% presence of the dominant trait, and 25% presence of the recessive trait in the F1 (first filial) generation. - If a plant with a dominant trait from the F1 generation (carrier, heterozygous dominant) is bred with a plant that shows a recessive trait, their offspring will display at 50/50 probability of dominance versus recessiveness. Thus, alleles expressing a particular trait via dominance/recessiveness, in the case of the pea plants, take the form of two alleles that combine to express a particular version. This later has been shown to be homozygous dominance/recessiveness, or heterozygous dominance.
A trait that is hidden?

Can zygote be defined as a basic unit of heredity information that influences a particular trait or traits?

True.
How do you use a sentence with heredity?
Heredity is the passing of genetic information from parents to offspring. An example sentence using heredity could be: "Eye color, height, and certain diseases can be influenced by heredity and are inherited from our parents."
How does heredity relate to DNA?
DNA (deoxyribonucleic acid) is the chemical which contains the information which determines heredity. Every inherited trait is the result of some particular DNA sequence. There are four types of DNA base chemicals, which can be connected in any sequence, and the specific sequence, known as a gene, will result in specific traits. Genetics has a language, written with only 4 letters.
What is the basic unit of heredity?
The basic unit of heredity is the gene, which is a segment of DNA that contains the instructions for a particular trait or characteristic. Genes are passed from parents to offspring and determine an individual's genetic makeup.
An organism that is heterozygous for a particular character will generally show the recessive trait?

Is diabetes a sex-linked trait?
no its a heredity thing
What is the name given to a specific region of DNA that codes for a particular heredity trait?
A gene is the name given to a specific region of DNA that codes for a particular hereditary trait. Genes contain the instructions for making proteins that determine traits such as eye color or blood type.
What does heredity unites mean?
the passing trait from parent to offspring.
What tool is used to show occurrence of a trait in a family?

Why is heredity important?
