What statement is true about heterozygous organisms?

Heterozygous organisms are more diverse than homozygous organisms. Heterozygous organisms can show either the dominant or the recessive trait. Heterozygous organisms always show the recessive traits.

Which is correct about a heterozygous organism?

A heterozygous individual is a diploid organism with two alleles, each of a different type. … Although each organism can have only two alleles, there can be many, many variations of a gene present in a population. Heterozygous is a description of the genotype, or combination of alleles present in an organism.

What does heterozygous organism have?

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). Carriers are always heterozygous.

Which is true about homozygous organism?

A ‘homozygous’ organism for a particular trait is described to possess either a pair of dominant alleles (e.g. AA) or a pair of recessive alleles (e.g. aa). True breeding organisms are homozygous since the trait in question can be held constant as they produce the same phenotypic result.

What does heterozygous mean in biology?

(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).

What is the best definition of heterozygous?


Heterozygous refers to having inherited different forms of a particular gene from each parent. A heterozygous genotype stands in contrast to a homozygous genotype, where an individual inherits identical forms of a particular gene from each parent.

What’s an example of heterozygous?

For every gene, you inherit two alleles: one from your biological father and one from your biological mother. … 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.

Is curly hair heterozygous?

Individuals with curly hair are homozygous for curly hair alleles. … Individuals who are heterozygous, with one of each allele have wavy hair, which is a blend of the expressions of the curly and straight hair alleles. Blood Typing/ Multiple Alleles. A number of human traits are the result of more than 2 types of alleles …

Is AA heterozygous or homozygous?

Two dominant alleles (AA) or two recessive alleles (aa) are homozygous. One dominant allele and one recessive allele (Aa) is heterozygous.

What is the full meaning of homozygous?

= Homozygous is a genetic condition where an individual inherits the same alleles for a particular gene from both parents.

Are purebreds homozygous?

Purebred – Also called HOMOZYGOUS and consists of gene pairs with genes that are the SAME. Hybrid – Also called HETEROZYGOUS and consists of gene pairs that are DIFFERENT. Genotype is the actual GENE makeup represented by LETTERS. Phenotype is the PHYSICAL appearance of a trait, such as a YELLOW (or BLUE) body color.

Homozygous examples

You can have brown eyes whether you’re homozygous (two alleles for brown eyes) or heterozygous (one for brown and one for blue). This is unlike the allele for blue eyes, which is recessive. You need two identical blue eye alleles in order to have blue eyes.
