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.
Which is an example of heterozygous allele quizlet?
Heterozygous alleles are alleles that act on different colors. For example allele for blue & allele for black.
What are 3 heterozygous examples?
As a second example of a heterozygous trait, consider human blood types. The three allele possibilities are types A, B and O. A and B are codominant; O is recessive. The heterozygote AO gives type A blood, while BO gives type B blood.
What is heterozygous example?
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 are examples of alleles?
An example of an allele is the gene that determines hair color. Either of a pair of genes located at the same position on both members of a pair of chromosomes and conveying characters that are inherited in accordance with Mendelian law. Any of the possible forms in which a gene for a specific trait can occur.
What is another name for an allele?
Allele, also called allelomorph, any one of two or more genes that may occur alternatively at a given site (locus) on a chromosome. Alleles may occur in pairs, or there may be multiple alleles affecting the expression (phenotype) of a particular trait.
Is AA homozygous or heterozygous?
Two dominant alleles (AA) or two recessive alleles (aa) are homozygous. One dominant allele and one recessive allele (Aa) is heterozygous.
What are alleles Quizizz?
What are alleles? Different versions of the same gene. Different versions of the same chromosome. Allele is a synonym of gene.
What is a heterozygous mutation?
A mutation affecting only one allele is called heterozygous. A homozygous mutation is the presence of the identical mutation on both alleles of a specific gene. However, when both alleles of a gene harbor mutations, but the mutations are different, these mutations are called compound heterozygous.
