What is an example of a heterozygous gene?
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.
What is heterozygous in simple words?
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 is an example of homozygous dominant?
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.
What is an 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 homozygote example?
Homozygote: A person who has two identical forms of a particular gene, one inherited from each parent. For example, a girl who is a homozygote for cystic fibrosis (CF) received the cystic fibrosis gene from both of her parents and therefore has cystic fibrosis.
What is the difference between homozygous and homologous?
Homologous chromosomes show complete homology between chromosomes while homeologous chromosomes show partial homology between two chromosomes. This is the key difference between homologous and homeologous chromosomes. Homeologous chromosomes originate due to a phenomenon called polyploidy, which takes place during the cell cycle.
What are the two types of homozygous?
Furthermore, there are two types of homozygous state: two dominant alleles or two recessive alleles. In contrast, if the two alleles do not match, we call it heterozygous for a trait. It is the state of having one dominant allele and one recessive allele.
What is the difference between homozygote and heterozygote?
Homozygous results in similar individuals with pure traits while heterozygous results in dissimilar individuals with different traits.
What does homozygous mean in genetics?
In genetics, homozygous is a term which is used to refer to an organism which has inherited two identical copies of a gene. For example, if a plant is homozygous for red flowers, it means that it has inherited two copies of the gene which tell it to produce red flowers.
