What is a homozygous genotype?
(HOH-moh-ZY-gus JEE-noh-tipe) The presence of two identical alleles at a particular gene locus. A homozygous genotype may include two normal alleles or two alleles that have the same variant.
What is homozygous quizlet?
homozygous. an organism that has two identical alleles for a trait (purebread) phenotype.
What example is a homozygous genotype?
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.
Whats a heterozygous genotype?
(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 meant by homozygous and heterozygous?
Heterozygous is when different forms of a specific gene are inherited from each parent. Homozygous is when a gene inherited from each parent is identical. Basically, heterozygous means different while homozygous means the same. 4.
What is genotype quizlet?
Genotype refers to the alleles you possess for a particular gene or set of genes. Phenotype is the physical trait itself, which may be influenced by genotype and environmental factors.
What is a genotype in biology quizlet?
genotype. The entire genetic makeup of an organism; also the combination of genes for one or more specific traits. Phenotype. An organisms appearance or other detectable characteristic that results from the organisms genotype and the environment.
Which is a heterozygous genotype quizlet?
The heterozygous genotype results in a third phenotype that is a tangle of the dominant and recessive traits. Both alleles in the proble are represented equally as dominant in the phenotype. The offspring of the organism varies because of the genotypes and phenotypes of the parent.
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 is the difference between homozygous and heterozygous quizlet?
Homozygous is having two identical alleles for a particular gene. Heterozygous is having two different alleles for a particular gene.
