What type of allele dominance occurs when both the alleles are active and expressed?
When both the alleles are expressed, it is called co-dominance or mixed dominance.
How are the genes lined up in a pair of chromosomes?
They are lined up in the same order in both chromosome pairs. They are organized in alleles.
How does codominance effect phenotype?
both alleles are expressed in the offsping
When both alleles are expressed in offspring is what?
Co-dominance.
What is the name of inheritance pattern in which both alleles are expressed equally?
It depends on what you mean by "both are expressed". In order for both alleles to be expressed, both alleles must be dominant alleles. If one allele is recessive, it will be masked. If you are talking about alleles that are co-dominant, then both alleles would be expressed together. Ex: Red x white = red and white flower If you are talking about incomplete dominance, then both alleles are seen as a blend of both in the offspring. Ex: red x white = pink flower If you are talking about multiple alleles (like in human blood typing), then you can see 2 alleles expressed together. Ex: Type A x Type B can produce AB blood type.
Why you called co-dominance when a person possess two different alleles at the same locus and both alleles are expressed in the phenotype?
Both of the parent's alleles are either dominant or recessive.

Which statement is TRUE about multiple alleles?
MULTIPLE CHOICES a. It happens when two or more alleles control the inheritance of a character. b. It refers to traits that are controlled by genes located on the same-sex chromosomes. c. It occurs when two dominant alleles of a contrasting pair are fully expressed at the same time in a heterozygous individual. d. It occurs when the phenotype of the offspring is somewhere in between the phenotype of both parents.
When neither allele is dominant (they are both expressed)?
Both of the alleles must be recessive. The trait expressed is a recessive trait.
How does codominance effect phenotype?
both alleles are expressed in the offsping
What are homologous choromosomes?
Homologous chromosomes are pairs of each other. They are chromosomes that are identical to each other except for a few variations. Everybody has one from their mom and dad. Everybody has 46 chromosomes, but in reality it is less confusing to say "we have 23 pairs of chromosomes."
What is it called when both alleles are expressed in an offspring?
This is called Codominance because both genes are expressed in an offspring.
When the alleles of a gene pair are expressed differently but neither is dominant to the other?
Codominance means that neither allele can mask the expression of the other allele. An example in humans would be the ABO blood group, where alleles A and alleles B are both expressed.
What Dominant alleles are both fully expressed in a phenotype?
The form of inheritance in which two (different) alleles are both expressed is called codominance. An example of codominance is the orange and black coat of a type of calico cat called a tortoiseshell. Both the orange allele and the black allele for coat color are expressed.
In some flowers there are two alleles for color and these can both be expressed equally at the same time Which best describes this trait?
Recessive
