Are the alleles for a trait from both parents found in one sex cell?

A sex cell is, by definition, a male sex cell or a female sex cell. Both are 1N and each contains half the genetic material of the parent that produced the cell. Parental traits are not combined until fertilization has occurred.

What alleles are mask in complete dominance?
A recessive trait is a trait with two contrasting alleles. In some cases contrasting alleles for a trait are codominan, that is, both are expressed.
Most copies of harmful recessive alleles are carried by?
individuals that are heterozygous for alleles
What is sickle cell Trait The condition is Autosomal and there is Codominance between alleles what does this mean?
sickle cell trait is inherited from one set of gene alleles from both parents. if you get two traits together it will cause sickle cell anemia which is a disease, sickle cell trait is not a disease. i dont know what autosomal means!! i dont know what codominance means!!
Why are two recessive alleles needed for a recesssive trait to be shown?
bcoz in case of one dominant and one recessive, dominant allele will express its characters and suppresses the recessive ones. so for the expression of recessive characters both allele should be recessive.
How are homozygous and heterozygous allele combinations for a particular trait in plants different?
A homozygous trait is expressed when 2 of the same alleles make up the genotype. For example, if two alleles (A and a) were present, the homozygous trait would be either AA or aa. In general, a fully recessive trait is only expressed when it's homozygous.
What alleles are mask in complete dominance?
A recessive trait is a trait with two contrasting alleles. In some cases contrasting alleles for a trait are codominan, that is, both are expressed.
What are both inherited alleles called?
Genetic makeup formed from both inherited alleles together is called a genotype. Homozygous alleles would be a pair of identical alleles for a single trait. Heterozygous is different alleles for a single trait.
What does it mean to be pure for a trait?
To be pure for a specific trait means that both of the alleles that comprise that trait are both dominant alleles.
What do geneticists call alleles that are both expressed in the phenotype when they are together?
Genetic makeup formed from both inherited alleles together is called a genotype. Homozygous alleles would be a pair of identical alleles for a single trait. Heterozygous is different alleles for a single trait.
When neither allele is dominant (they are both expressed)?
Both of the alleles must be recessive. The trait expressed is a recessive trait.
When neither allele is dominant what are they expressed as?
Both of the alleles must be recessive. The trait expressed is a recessive trait.
What is trait called that appear only when both alleles are present?
"recessive"
Most copies of harmful recessive alleles are carried by?
individuals that are heterozygous for alleles
Can a baby be born with positive blood if both parents are negative?
No. If both parents are Rh negative, they are homozygous recessive for the Rh factor and can only pass on recessive alleles to their children, and a positive Rh factor is a dominant trait.
What is sickle cell Trait The condition is Autosomal and there is Codominance between alleles what does this mean?
sickle cell trait is inherited from one set of gene alleles from both parents. if you get two traits together it will cause sickle cell anemia which is a disease, sickle cell trait is not a disease. i dont know what autosomal means!! i dont know what codominance means!!
Can 2 A positive parents have an O negative child?
No. O and Rh negative are both recessive traits--both alleles must be that trait before it expresses. The term for an A positive child from two O negative parents is "grounds for divorce."
What does homozgous mean?
Homozygous means that you have identical alleles for a trait. Example: For females, both alleles are XX. Males are heterozygous, with XY.
