True or False In heterozygous individuals only the recessive allele is expressed?
In heterozygous individuals, only the dominant allele is expressed. The recessive allele is present, but not expressed
If a pattern of inheritance for a trait is complete dominance then an organism heterozygous for the trait would normally express?
If a trait is dominant, then an organisms heterozygous (hybrid) for that trait would normally show: A) The recessive trait only B) The dominant trait only C) A blend of the recessive and dominant traits D) A phenotype unlike that of either parent B) The dominant trait only! Reason being because heterozygous means the pair of genes are different. When this occurs, only the dominant trait is expressed.
What is a trait expressed when two different genes for the same trait present?
If the two different genes include one dominant allele and one recessive allele, which is the heterozygous genotype, the dominant phenotype is expressed. For example, if R represents the red flower allele and r represents the white flower allele, the flowers would be red. If the trait is governed by incomplete dominance, then the heterozygous genotype (Rr) will produce an intermediate phenotype, such as pink.
What is one question about how traits are expressed when an organism has heterozygous alleles for a trait?
i think its i honestly dont know
What is it called having a dominate and recessive allele?
If an individual has one recessive allele and one dominant allele, they are known as heterozygous. The dominant trait will be expressed.
True or False In heterozygous individuals only the recessive allele is expressed?
In heterozygous individuals, only the dominant allele is expressed. The recessive allele is present, but not expressed
What is the type of allele that only effect the phenotype in the homozygous chromosome?
Recessive. Dominant alleles are expressed in both homozygous and heterozygous individuals (DD or Dd), but recessive alleles are only expressed in homozygous individuals (dd).

What genotype will be produced by a heterozygous?
The trait that would be expressed in a heterozygous genotype would be the dominant trait. If one allele is dominant then it will be expressed.
Does your analysis support or refute mendels hypothesis of dominant and recessive inheritance?
You are from Kerr. The answer is on the textbook. The analysis does support the hypothesis because some of the offspring's genotype is heterozygous, as they have two different alleles. They do not have the recessive traits expressed, except in organisms that are homozygous recessive. You're so welcome.
Is recessive the process in which DNA changes to form new alleles?
No, recessive traits refer to the inheritance pattern of the allele. In the simple case where a trait is either expressed or not, if it is a recessive trait it will only be the expressed phenotype when it is homozygous. Dominant allele phenotypes will show if the genotype is heterozygous.
How do you use monohybrid in a sentence?
Heterozygous means having different alleles on corresponding sites on the two chromosomes. Here are some sentences.We studied heterozygous traits in class today.Her genes are heterozygous for eye color.Many genes are heterozygous, and the dominant trait is expressed.
What does it mean if there is two different alleles for a trait?
The trait could show up in two different forms. Alleles are individual units that determine what trait will be expressed in an offspring. Alleles exist for most traits such as hair color or wing size. Having two alleles simply means that the trait can be expressed in different variation. One trait can have several different alleles.
How is phenotype expressed in a incomplete dominance?
It's expressed when a heterozygous phenotype is between two homozygous phenotypes.
Individual that has one copy of a expressed gene has a genotype known as?
Heterozygous.
What are the circumstances under which dominant alleles will be expressed?
A dominant allele will be expressed when an allele pair is homozygous or heterozygous dominant.
What makes a dominant allel different from?
A dominant alle masks the expression of the recessive trait in a heterozygous genotype, a recessive allele is the phenotpye expressed is the recessive trait.
