Which phenotype is dominant and recessive?

Which phenotype is dominant and recessive?

Some alleles are considered dominant, meaning if you get one allele for the trait, that’s going to be your phenotype. Other traits are recessive. They are masked by the dominant phenotype, and you need to get two copies of that trait to see it in your phenotype.

Can a single allele be both dominant and recessive?

Some alleles are dominant or recessive. When an organism is heterozygous at a specific locus and carries one dominant and one recessive allele, the organism will express the dominant phenotype.

What does it mean to phenotype if one allele is dominant over another?

complete dominance
In complete dominance, only one allele in the genotype is seen in the phenotype. In codominance, both alleles in the genotype are seen in the phenotype. In incomplete dominance, a mixture of the alleles in the genotype is seen in the phenotype.

What’s a recessive phenotype?

Definition. A phenotype that requires two copies of the causal variant in an individual to occur.

What is the dominant phenotype?

Organisms that reproduce sexually carry genes from each parent. The genes that are expressed are responsible for your traits, or phenotype. A dominant phenotype is a trait resulting from a dominant gene.

What is a recessive phenotype?

Is the phenotype of a dominant allele never seen?

C. The phenotype of a dominant allele is never seen in the F1 progeny of a monohybrid cross. D. A testcross can be used to determine whether an individual is homozygous or heterozygous for a dominant allele. E. All of these statements are true.

What kind of genetic condition does a man have?

Both parents have homozygous dominant genotypes. One parent is homozygous dominant, and the other is heterozygous. One parent is homozygous dominant, and the other is homozygous recessive. A man has a recessive genetic condition. His wife does not have this condition.

Which is a recessive gene that causes hemophilia?

Hemophilia is caused by a recessive gene, causing a failure of a transport mechanism. Hemophilia is caused by a recessive sex-linked genetic disorder or mutation of genes coding for proteins.

What causes a man to have freckles but one of his parents does not?

A man has freckles but one of his parents does not have freckles. What is his genotype? Freckles are caused by a dominant allele. A man has freckles but one of his parents does not have freckles. The man has fathered a child with a woman that does not have freckles.
