the 2 alleles of the gene for the trait are different on the 2 homologous chromosomes
Being heterozygous for a trait means that they have different alleles for a trait. For instance: Tt would be heterozygous and TT or tt would be homozygous because they are both eitehr little or big t's.
it mean the gene is not pure or for example suppose a person is blood group A but actually he is having A and O; because O is recessive trait the gene express the A trait instead, making the person having blood group A.

What does carrier mean in science terms?
A carrier is an organism that inherits a specific genetic trait but does not show the trait in their phenotype, or physical appearance.
What does Sandra is heterozygous for eye shape mean.?
To put it best in words, Sandra has two different alleles for eye shape. So one parent has a certain eye shape, while the other has a different eye shape. Sandra will gain the dominant trait for her eye shape.
What is a dominat trait dictionary?
A dominant trait is part of genetics in which a trait will appear in an offspring if one parent contributes it. For example, if one parent contributes the dominant trait of dark hair and the other contributes the recessive trait of light hair, the offspring would have dark hair.
Linkage studies refer to tracing a particular trait within a family does this mean that twin and adoption studies are a type of linkage study?
No. Linkage studies use markers to identify chromosomal regions that may be linked to disease. Twin and adoption studies establish heritability and thus the genetic basis of a disease, not which chromosome or chromosomal region may be implicated. For this reason they are called genetic epidemiological studies.
Is unibrow dominant or recessive?
its neither. its a learned skill. i can do it, and i learned to by holding one eyebrow up, with my finger, and learning to adapt from that. you use muscle in your face when you do it. if you want to learn, wrinkle your forehead that will help you.
What heterozygous mean?
Heterozygous means that you are carrying 1 dominant trait and 1 recessive trait.If an allelic pair has one dominant and other recessive gene it is called heterozygous.

What is a heterozygous person called?
A heterozygous person is called a carrier for the specific trait or gene they carry. This means they have two different alleles for a particular gene, with one dominant and one recessive allele. It is important to note that being heterozygous for a genetic disorder does not necessarily mean the individual will exhibit symptoms of the disorder.
What does family trait mean?
genetic likeness.
What does does heterozygous mean?
Heterozygous means that you are carrying 1 dominant trait and 1 recessive trait.If an allelic pair has one dominant and other recessive gene it is called heterozygous.
What does it mean to be heterozygous for a trait?
One cannot really be heterozygous for a trait. You can be heterozygous for a gene, and based on the whether that gene is dominant or recessive will determine if you express that trait or not. Humans (and most organisms) carry two copies of each chromosome. As such, for a given genetic sequence, there can be three possibilities (there are exceptions, but let's keep it simple for now). The genes A)both code for the trait, B) neither code for the trait, or C) One gene does and the other does not. The C option is is being heterozygous. Let's get an example now: Assume that in some animal, there are only two hair colors -- Black or White. Also, the Black Hair color is Dominant. The black hair color is coded by the uppercase letter "B" and the white hair color is coded by the lowercase letter "b". An animal with the coding "BB" is HOMOZYGOUS for Black hair because BOTH genes code for black hair. Similarly, an animal coding "bb" will have White hair, because BOTH genes code for white hair. Now, let's say these two animals mate and have a baby coding with "Bb". This baby will have BLACK hair because the Black hair color is dominant and overpowers the White hair gene. To be Heterozygous (usually) means that you will express the dominant version of the trait, BUT your offspring/children can possibly get the recessive version of the trait.
What term describes an organism with two different alleles for a trait?
Heterozygous, or hybrid. This being because a heterozygous and a hybrid mean that they phenotype consists of two different genes. For example straight hair is dominant to curly hair, S being straight and s being curly. Some people may have SS, meaning they have straight hair, and others may have ss, meaning they have color hair. But in some cases, some people would have Ss making them heterozygous. SS or ss would be homozygous.
What does it mean to be homozygous dominant heterozygous or homozygous recessive?
Homozygous means "same" so a homozygous recessive trait would be a same [with parents] trait that is not the stronger trait which is dominant. Dominant is stronger showing trait, recessive is weaker trait. If you are dealing with Punnett squares then tt is homozygous recessive and TT is homozygous dominant. Hope this helped...
What is hetegeneous?
If you mean heterozygous, it is the condition in which the genotype for a trait contains two different forms, called alleles, of the same gene.
What does carrier mean in biology?
carrier--- if someone has part of a disease in their genetics but does not have the diseas themself eg. rets syndrome. It's also the person who is heterozygous for the trait, or disease. Ex: Mn, Jj, Kk, Ll, Tt, ect..
What does "het" mean in snakes and how does it affect their genetics and breeding?
"Het" in snakes refers to a genetic trait known as heterozygous, meaning the snake carries a recessive gene for a particular trait without showing it. When breeding snakes, knowing if a snake is "het" for a specific trait is important for predicting the likelihood of offspring inheriting that trait. Breeding two "het" snakes for the same trait can result in offspring that express the trait, while breeding a "het" snake with a non-"het" snake can produce offspring that are also "het" for the trait.
What does homozgous mean?
Homozygous means that you have identical alleles for a trait. Example: For females, both alleles are XX. Males are heterozygous, with XY.
