If two different alleles for a trait are present and one allele doesn't entirely block the expression of the other What is the genetic situation called?

Then they are codominent and a little bit of each will show up in the organism's phenotype.

Why cant sister chromatids have different alleles?
Sister chromatids dont over cuz they dont look it up lmfao
What kind of alleles does a heterozygous individual have?
2, it means that both of the alleles are different when compared to homozygous. Homozygous alleles are like aa or AA. Heterozygous simply means Aa so it has one dominant and one recessive allele
An organism is heterozygous at two genetic loci on different chromosomes?
Two different alleles for a trait.
How do you get from DNA the information molecule to the phenotype Ie- how is the genetic information expressed?
Genes on DNA make proteins by transcription and translation. Different alleles mean different proteins which consequently stand for different phenotypes. It is explicit in the case of one's blood type since proteins like antigen A or antigen B directly lead to different phenotypes. In some cases of shapes, DNA information expression may be implicit. For example. a deficient enzyme coded by recessive alleles fails to turn sugars into starch for storage in a seed. Therefore, the seed swells with plenty of water flowing in(osmosis). When it gets dried, it turns wrinkled. On the other hand, the dominant alleles express a round shape due to the normal enzyme that remains the content full of starch rather than water.
What is variation in evolution?
A variation of a gene is called and allele. Different alleles are caused by mutations.
Different forms of gene?
Alleles are the different types of genes.
What makes a dominant alleles different from a recessive alleles?
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.
For each trait there are allele possibilities?
Yes, that is correct. Each trait is controlled by genes, and genes exist in different forms called alleles. For any given trait, an individual can have two alleles—one inherited from their mother and one from their father. These alleles can have different variations, resulting in different expression of the trait.
A husband and wife have two sons one boy has a straight thumb while the other has a bent thumb what causes the difference?
The brothers have different alleles. They received different alleles from their parents
What will a population with different alleles have?
A population with different alleles will have traits
What is the expression of a trait and determined by the combination of alleles Called the?
genotype
What term describes a pair of alleles that are the same?
Alleles that are the same = homozygous Alleles that are different = heterozygous
What is the expression of a trait call and determined by the combination of alleles called what?
genotype
Two different forms of the same gene are called?
Alleles
What genotype has different alleles?
The genotype that has two different alleles is heterozygous
Different versions of the same gene are called?
Different versions of the same gene are called
What is an organism that has two different alleles called?
There are three alleles, the dominant, uppercase 'T', and recessive, 't'. There is also codominance, which is when two separate alleles neither control and create something entirely diffierent ie: Straight haid allels, 'S', and curly hair allele, 'C', create wavy hair. The correct answer to this question is: Heterozygot. An organism with the same alleles at a gene locus is called a Homozygot. Hetero- often meaning "different" as in "Heterosexual -> different sex attraction " and "Homo-" often meaning "same" as in "homosexual -> same sex attraction".
