Do all heterozygous pairs of allele produce an intermediate phenotype?
No
If the dominant allele F produces yellow flower color and re recessive allele f produces white flower color what are the possible pairs of alleles that would produce the yellow-flower phenotype?
FF, fF, Ff
How is a recessive alle different from a dominant allele?
its different because adominant allele is in charge
When do allele pairs separate?
meiosis 1
What is the multiple allele system?
A multiple allele system is when there are more than two possible allele pairs for a single locus.
What is An organisms allele pairs?
Genotype
Do all heterozygous pairs of allele produce an intermediate phenotype?
No
How are an individual's genotype and phenotype different?
The genotype of an organism is the group of characteristics derived from a combination of heredity and environmental factors. Genotype is based on genetic factors only. phenotypes are the genes that an organism carries. For example, the gene for blue eyes could be b and the gene for brown eyes could be B. Bb is a genotype. Phenotype is the trait that show up. Since brown eyes are dominant, the phenotype of Bb would be brown eyes.
How to calculate gametes?
Example 1: There are 5 gene pairs, how many gametes can be formed if only 3 of them are heterozygous? There are two ways you can work out this problem, it depends on the genotype and phenotype. As you calculate the genotype you take 2 and raise it to the number of heterozygous gene pairs, which in our case is 3; so it would read, 2^3=8 different gametes. If we took the phenotype you would take the inverse of 2 and raise it to the number of heterozygous gene pairs which is 3; so it would read 1/2^3 which equals 1/8=0.125 different gametes dilse2 said .................................................... Number all probable gametes = 2n x m where n = number of heterozygous allele pairs m = number of homozygous allele pairs for your question n = 3 m = 2 Number all probable gametes = 23 x 2 = 16
How can a genotype change a phenotype?
no not always due to some phenotypes having more than one gene sequence that affects it, eg; the base sequence for a certain enzyme's synthesis could be TTT but by substituting a T with a C to make TTC in mutation could still be a code for the same enzyme...
What are the different forms of a gene called?
Alleles are the different forms of a gene.Alleles are corresponding pairs of genes located at specific positions in the chromosomes. Together, alleles determine the genotype. Alleles which determine some aspect of the phenotype, the physical appearance of an organism, are said to be coding alleles.When both alleles in a pair are the same, the alleles are homozygous. If the alleles are different, they are heterozygous. In the case of homozygous alleles, the expression of phenotype is usually very straightforward. In heterozygous instances, however, the phenotype of the organism is determined by which allele is dominant, meaning that one allele overrides the other.In the case of eye color in humans, if someone inherits a blue allele and a brown allele, his or her eyes will be brown, because brown is a dominant genetic trait, requiring only one allele for expression. However, if that person had a child with someone who also carried a blue allele and both parents passed the blue trait down, the child would have blue eyes. This explains why blue-eyed children sometimes randomly pop up in a brown-eyed family: because someone in the family's genetic history had blue eyes.

When two allele pairs are identical it is considered to be?
Homozygous is the term used to describe an organism with two allele pairs that are identical, in reference to dominant characteristic traitÊin heredity.
A trait that is masked by a dominant trait is called?
DNAactually it is not DNA at all, a dominant trait, masks a recessive trait.
What is geno-type?
A gene in the body or plant or animal etc, that can not be seen.
How is a recessive alle different from a dominant allele?
its different because adominant allele is in charge
