Examples of heterozygous and homozygous?

Examples of homozygous and heterozygous used in a sentence

• 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 an example of a 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 homozygous and heterozygous?

Homozygous: You inherit the same version of the gene from each parent, so you have two matching genes. Heterozygous: You inherit a different version of a gene from each parent.

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.

Is BB heterozygous or homozygous?

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). Heterozygous individuals contain two different alleles which results in conflicting instructions.

Is JJ dominant or recessive?

Another gentleman does not possess this gene - instead, he has the recessive jj gene which means his joints bend normally. A boy is born with an extra finger on each hand due to the dominant gene EE, while another newborn with the recessive homozygous ee gene has the normal number of fingers on her hands.

What is allele example?

The definition of alleles are pairs or series of genes on a chromosome that determine the hereditary characteristics. An example of an allele is the gene that determines hair color. ... Any of the alternative forms of a gene or other homologous DNA sequence.

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.

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.

What is a real life example of heterozygote advantage?

Heterozygous advantage is one of several controversial explanations for the existance of genetic variability in natural populations. The classic example of heterozygous advantage is sickle cell anemia where humans who are homozygotic for sickle shaped cells (pictured opposite) suffer from a near lethal condition.

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.

Is AA a heterozygous genotype?

Individuals with genotype Aa are heterozygotes (i.e., they have two different alleles at the A locus).
