Is a dominant or recessive variant of a particular gene?
A dominant variant of a gene is expressed when only one copy of the variant is present, masking the recessive variant. In contrast, a recessive variant is expressed only when two copies of the variant are present.
How do you write alleles?
Alleles are represented by letters, and two letters are used for each gene to denote the alleles inherited from each parent. For example, "Aa" represents a heterozygous individual with one dominant allele (A) and one recessive allele (a) for a particular trait. When writing alleles, uppercase letters are typically used to represent dominant alleles and lowercase letters are used for recessive alleles.
How is codominance same as having no dominat?
The genotype of the offspring affects the triple allels setup which causes the living organism it self to not be adaptable to recessive or dominant allels causing damage to the nucleus of each 69 pairs of chromosoms
What can be dominant or recessive?
Alleles can be dominant or recessive
What are the differences between heterozygous and homozygousand how to dominate and recessive allels play a role in it?
well, homozygous means that both allels are the same exp: AA, or AA. heterozygous means that the allels are different exp: Aa, or aA. when it is dominant that means that it is either Aa, or aA in order for it to be dominant it has to have a capital letter in it. if it is recessive then it must be AA only because both the letters are lowercase. ask your teacher, or someone else you know or even look it up in the dictionary about a punnet square.
Is melanoma dominant or recessive?
is malignant melanoma dominant or recessive
Explain why the homozygous recessive would always be used in a test cross?
The homozygous recessive individual is used in a test cross to determine the genotype of an individual with a dominant phenotype but unknown genotype. When crossed with a homozygous recessive individual, if any offspring display the recessive trait, it indicates that the unknown individual is heterozygous for that trait.
What is the difference dominant and recessive trait?
Dominant traits are the traits that mask the recessive traits. The dominant traits are stronger than recessive!
Is a situation in which a dominant allele completely masks a recessive allele for a gene.?
If you have 2 dominant alleles, the gene will be dominant, if you have 2 recessive alleles, the gene will be recessive. But if you have 1 recessive and 1 dominant, the Dominant allele will mask the recessive one.
How do you xxplain dominant and recessive?
Recessive
Is AAA recessive or dominant?
recessive
When does a recessive trait dominant over a dominant trait?
A recessive trait cannot be dominant over a dominant trait. Dominant traits are always expressed over recessive traits in heterozygous individuals because they mask the expression of the recessive trait.
