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.
Is HH An example of homozygous?
A full head of hair is a dominant feature, with the homozygous gene of HH. However, the recessive trait – baldness – can be manifested in an individual with the homozygous recessive gene, or hh. … Its recessive trait, represented by the homozygous gene hh, is straight hair.
What is an example of a 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.
What is phenotype example?
Examples of phenotypes include height, wing length, and hair color. Phenotypes also include observable characteristics that can be measured in the laboratory, such as levels of hormones or blood cells.
How do you say the word homozygous?
Also ho·mo·zy·got·ic [hoh-moh-zahy-got-ik, hom-oh-].
What are 3 heterozygous examples?
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.
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 …
What means allele?
An allele is a variant form of a gene. Some genes have a variety of different forms, which are located at the same position, or genetic locus, on a chromosome. Genotypes are described as homozygous if there are two identical alleles at a particular locus and as heterozygous if the two alleles differ. …
