What is an organism with two traits?

What is an organism with two traits?

An organism which has two different alleles of the gene is called heterozygous. Phenotypes (the expressed characteristics) associated with a certain allele can sometimes be dominant or recessive, but often they are neither.

What is an example of a heterozygous organism?

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).

What does it mean when an organism is heterozygous for a trait?

To be heterozygous for a trait is to have different alleles for it. Being homozygous for a trait means that it will always turn out the same. But being heterozygous means that the trait can develop in different ways. Remember, an organism isn’t said to be homozygous or heterozygous overall—just for a single trait.

What are the two types of heterozygous?

Homozygous: You inherit the same version of the gene from each parent, so you have two matching genes. Heterozygous: You inherit a different version of a gene from each parent.

Which of the following is an example of a heterozygous genotype?

An organism with one dominant allele and one recessive allele is said to have a heterozygous genotype. In our example, this genotype is written Bb.

Is heterozygous and heterozygote same?

individuals in a population are heterozygotes at that locus. In a heterozygous individual the two genes for a trait, one received from the mother and the other from the father, are different. The proportion of heterozygotes in the population is, therefore, the same as the probability that two genes taken…

What is a simple definition of heterozygous?

(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 trait will a heterozygous individual express?

Specifically, heterozygous (Ss) individuals express both normal and sickle hemoglobin, so they have a mixture of normal and sickle red blood cells. In most situations, individuals who are heterozygous for sickle-cell anemia are phenotypically normal. Under these circumstances, sickle-cell disease is a recessive trait.

Which is a heterozygous genotype *?

A heterozygous genotype is a genotype that has multiple different alleles present in that gene. For example, a genotype that is “Tt” would be heterozygous, where the capital “T” could represent the trait of “tall” and the lowercase “t” could represent the trait of short.

Which is the best definition of a heterozygous trait?

1 Heterozygous refers to having different alleles for a particular trait. 2 When alleles are heterozygous in complete dominance inheritance, one allele is dominant and the other is recessive. 3 The genotypic ratio in a heterozygous cross where both parents are heterozygous for a trait is 1:2:1.

What kind of wings does a heterozygous fly have?

Flies that do not inherit the dominant allele have wrinkled wings. Flies that are heterozygous for the trait, having one dominant and one recessive allele, exhibit normal wings. The process by which alleles are transmitted was discovered by Gregor Mendel and formulated in what is known as Mendel’s law of segregation.

What happens when the unknown plant is heterozygous?

If the genotype of the unknown plant is heterozygous, half of the offspring will have the dominant trait (purple), and the other half will exhibit the recessive trait (white). If the genotype of the unknown plant is homozygous dominant (PP), all of the offspring will be heterozygous (Pp) and have purple petals.

What is the genotypic ratio of a heterozygous cross?

The genotypic ratio in a heterozygous cross where both parents are heterozygous for a trait is 1:2:1. The genotypic ratio in a heterozygous cross where one parent is heterozygous and the other is homozygous for a trait is 1:1. Reece, Jane B., and Neil A. Campbell.
