What is the difference between homozygous and heterozygous give examples of each?
If you have two copies of the allele for blonde hair, you are homozygous for that trait. Having one copy of the allele for blonde hair and one copy of the allele for brown hair makes you heterozygous for hair color.
What is the difference between homozygous and heterozygous quizlet?
Homozygous is having two identical alleles for a particular gene. Heterozygous is having two different alleles for a particular gene.
What is the difference between homozygous and heterozygous for kids?
Homozygous and heterozygous are terms that are used to describe allele pairs.

Homozygous vs Heterozygous.
| Homozygous | Heterozygous |
|---|---|
| Contains only one type of allele, either dominant or recessive | Contains different alleles for a trait. Both dominant and recessive |
What is the difference between heterozygous and heterozygote?
individuals in a population are heterozygotes at that locus. In a heterozygous individual the two genes for a trait, one received from the mother and the other from the father, are different. The proportion of heterozygotes in the population is, therefore, the same as the probability that two genes taken…
What is an example of heterozygous?
Together, these alleles are called a genotype. If the two versions are different, you have a heterozygous genotype for that gene. For example, being heterozygous for hair color could mean you have one allele for red hair and one allele for brown hair.
What is a simple definition of heterozygous?
(HEH-teh-roh-ZY-gus JEE-noh-tipe) The presence of two different alleles at a particular gene locus. A heterozygous genotype may include one normal allele and one mutated allele or two different mutated alleles (compound heterozygote).
How are a heterozygous and a homozygous individual different group of answer choices?
Homozygotes have one chromosome while heterozygotes have two similar chromosomes. Heterozygotes carry two copies of a gene while homozygotes only carry one.
What is the definition of heterozygous quizlet?
heterozygous. an organism that has two different alleles for a trait (hybrid)
Are humans heterozygous or homozygous?
Since humans possess two copies of each chromosome, they also have two copies of each gene and locus on those chromosomes. Each of these trait-encoding genes (or loci) is called an allele. If the alleles match, the person is homozygous for that trait.
What does it mean if someone is homozygous?
Homozygous describes the genetic condition or the genetic state where an individual has inherited the same DNA sequence for a particular gene from both their biological mother and their biological father. It’s often used in the context of disease.
What happens when you cross a heterozygous with a homozygous?
For a gene that is expressed in a dominant and recessive pattern, homozygous dominant and heterozygous organisms will look identical (that is, they will have different genotypes but the same phenotype), and the recessive allele will only be observed in homozygous recessive individuals.
Is heterozygous good or bad?
Heterozygotes and Genetic Diseases
Heterozygotes can get genetic disease, but it depends on the type of disease. In some types of genetic diseases, a heterozygous individual is almost certain to get the disease. In diseases caused by dominant genes, a person needs only one bad copy of a gene to have problems.
Can heterozygous be dominant?
If the alleles are heterozygous dominant, the faulty allele would be dominant. In such a case, the person may or may not be affected (compared to homozygous dominance where the person would be affected).
Which blood type is homozygous?
The possible human phenotypes for blood group are type A, type B, type AB, and type O. Type A and B individuals can be either homozygous (IAIA or IBIB, respectively), or heterozygous (IAi or IBi, respectively).
What is another word for heterozygous?
In this page you can discover 11 synonyms, antonyms, idiomatic expressions, and related words for heterozygous, like: homozygous, genotype, MTHFR, rb1, allele, recessive, C282Y, heterozygote, wild-type, premutation and homozygote.
Is homozygous dominant or recessive?
Homozygous means that the organism has two copies of the same allele for a gene. An organism can be homozygous dominant, if it carries two copies of the same dominant allele, or homozygous recessive, if it carries two copies of the same recessive allele.
How can you tell if someone is heterozygous or homozygous for a dominant trait?
To identify whether an organism exhibiting a dominant trait is homozygous or heterozygous for a specific allele, a scientist can perform a test cross. The organism in question is crossed with an organism that is homozygous for the recessive trait, and the offspring of the test cross are examined.
Is TT a heterozygous or homozygous?
| Genotype | Definition | Example |
|---|---|---|
| Homozygous | Two of the same allele | TT or tt |
| Heterozygous | One dominant allele and one recessive allele | Tt |
| Homozygous dominant | Two dominant alleles | TT |
| Homozygous recessive | Two recessive alleles | tt |
Is BB homozygous or heterozygous?
homozygous
An individual that contains two different alleles of a gene is heterozygous. A cow that has two alleles for a red coat is homozygous (bb). A bull with two alleles for a black coat is homozygous (BB).
Is GG homozygous or heterozygous?
Organisms that have two different alleles for a gene are called heterozygous (Gg).
