What else can I help you with?
Will a A trait controlled by a dominant gene be expressed even if the instructions of the corresponding gene in the other half of the pair are different?
Yes, if a trait is controlled by a dominant gene, it will be expressed regardless of the instructions of the corresponding gene in the other half of the pair. Dominant genes only require one copy to be expressed in the phenotype.
A square box half colored in a pedigree is?
A square box half colored in a pedigree typically represents a carrier of a genetic trait. This means the individual carries one copy of the gene mutation for the trait but does not exhibit the trait themselves.
If the male parent is heterozygous for a trait what alleles for each sperm cell possibly have?
A heterozygous male parent has two different alleles for a trait. During gamete formation, each sperm cell will carry one of the two alleles, either the dominant or recessive allele. This means that half of the sperm cells will carry one allele and the other half will carry the other allele.
Can a single gene control a single trait.?
It was once believed that one gene controls one trait, so it is possible. Currently, the belief is that one gene can interact with other genes to control a trait, and that one gene can control more than one trait.
What do geneticists call a trait that hides other traits?
Geneticists call a trait that hides other traits a "recessive trait." When an individual has one dominant and one recessive allele for a specific trait, the dominant allele will be expressed, masking the effects of the recessive allele.
When the trait has more two alleles how is the trait inherited?
One parent has a recessive trait. For example: One parent has blood type AB, the other has blood type OO.
What type of trait prevents the other type from being seen?
A recessive trait. When a recessive allele is with a dominant allele, only the dominanate trait can be seen.
What does a half shaded circle or square indicate in a pedigree?
A half-shaded circle or square in a pedigree indicates that the individual is a carrier of a certain genetic trait. This means they have one copy of the gene for the trait but do not express the trait themselves.
What is a trait that is passed on from one generation to the other called?
Heriditary.
What is haritability?
ability of a trait to he/she passed from one servation to the other
What is the sickle cell trait of sickle cell anemia?
The sickle cell trait is that you dont have the whole thing you have half of it which is called the trait
One trait masking another form of a trait?
Incomplete dominance is when one allele does not completely mask another allele, resulting in an intermediate phenotype. This can occur when both alleles contribute to the trait, rather than one completely dominating the other.
