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). A calf that has one allele for red coat color and one allele for black coat color is heterozygous (Bb).

What is an example of heterozygous?
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. The relationship between the two alleles affects which traits are expressed.
What is an example of homozygous and heterozygous?
Heterozygous means that an organism has two different alleles of a gene. For example, pea plants can have red flowers and either be homozygous dominant (red-red), or heterozygous (red-white). If they have white flowers, then they are homozygous recessive (white-white).
Are humans homozygous or heterozygous?
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 is heterozygous cat?
Diploid organisms (such as cats) have two sets of chromosomes. This means that each gene is present in two copies. ... If the two alleles are the same, the organism is homozygous. If the two alleles are different, the organism is heterozygous.
What is genotype example?
Genotype examples
A gene encodes eye color. ... If the child inherits two different alleles (heterozygous) then they will have brown eyes. For the child to have blue eyes, they must be homozygous for the blue eye allele.
What is homozygous example?
If an organism has two copies of the same allele, for example AA or aa, it is homozygous for that trait. If the organism has one copy of two different alleles, for example Aa, it is heterozygous. Keep in mind that an organism can't simply be 'homozygous,' period.
Are blue eyes homozygous?
Finally, the genotype of an organism with two recessive alleles is called homozygous recessive. In the eye color example, this genotype is written bb. Of these three genotypes, only bb, the homozygous recessive genotype, will produce a phenotype of blue eyes.
Are chromosomes heterozygous?
Heterozygous (and its less common form heterozygotic) means “relating to a cell that has two different alleles for a particular gene at corresponding positions on homologous chromosomes.”
What is an example of homozygous dominant?
A homozygous dominant genotype is one in which both alleles are dominant. For example, in pea plants, height is governed by a single gene with two alleles, in which the tall allele (T) is dominant and the short allele (t) is recessive.
Are alleles DNA?
Alleles are forms of the same gene with small differences in their sequence of DNA bases. ... Genes are made up of DNA. Each chromosome contains many genes.
What is example of phenotype?
The term "phenotype" refers to the observable physical properties of an organism; these include the organism's appearance, development, and behavior. ... Examples of phenotypes include height, wing length, and hair color.
Are females heterozygous or homozygous?
Women inherit two X chromosomes, one from each parent. So a female can be considered homozygous or heterozygous about a specific trait on the X chromosome. Men are a little more confusing.
Are calico cats Codominance?
Calico is a coat color found in cats, which is caused by a SEX-LINKED, CODOMINANT allele.
What are dominant traits in dogs?
Dominant vs.
What's the difference? Well, dominant traits require only one copy of a specific gene for the trait to be expressed in a dog. So, if either the mother or the father pass on a dominant trait—such as floppy ears, for example—the offspring will present the trait.
Are calicos male?
The calico fur pattern is predominantly white, with patches of two other colors — in David Bowie's case, orange and black. And because a cat's fur color is linked to its cells' X chromosomes, calico cats are rarely male. Male cells have only one X chromosome, meaning normally, males are just one color.
