What happens when a single gene has two alleles?
Two alleles represent a gene. ETC- The paternal (fathers) allele is B (for brown eyes) The mothers (maternal) is b ( for blue eyes) The capital B is the dominant allele, lowercase b is recessive. Therefore, a punnet square will show the offspring can be either hetrozygous or homozygous (recessive or dominant) Alleles represent the charactersitic, while a gene is a segment of DNA where heredity is based.
What form is a gene that is always expressed if present?
This is the dominate gene, and is normally represent by a capital letter. Then gene which is not expressed is the recessive gene and is represented by a lower case letter. For example the if someone had expressed a brown eyed phenotype and did not carry the gene for blue eyes it be represented as BB (B standing for Brown). If they expressed the brown eye phenotype and also carried the gene for blue eyes it would be represented as Bb (b does not stand for blue it stands for NOT BROWN) While if someone had blue eyes it would be represented as bb
What is the difinition of alleles?
An allele is a form of a gene. For example, the allele B may lead to black fur and the allele b may lead to white fur. Both B and b are alleles for fur colour.In general notation, dominant alleles are written with a capital letter (eg. B, T, P) and recessive alleles are written with a lower case letter (eg. b, t, p). A person will have two alleles (one from each parent) for every gene. Dominant alleles are expressed over recessive alleles.
Would blood group changes in neonate?
no. The ABO system and Rh blood group are already decided the moment sperm meets ovum. It is decided by the gene we have. For ABO classification, to put it simply people with A blood type has two A gene or one A gene plus one O gene. People with B type have two B gene or one B gene plus one O gene. People with AB type has one A gene and one B gene. O type has two O genes. A father passes one of his blood gene to his child and a mother passes one as well that the child now has two, and the combination is what decides the child's blood type. Bombay type is a very rare blood type different from A, B, or O. You can only have it if your family has a very rare gene, or in other words, if one of your family has it.
When gene pairs are written the dominant allele has an?
Capital letter (recessive is lowercase)

What is the copy of a gene?
When a gene may be represented by the capital letter N, the gene pair is 2N.
What do you call is the stronger gene represented by a capital letter?
Dominant gene. The gene represented by a lower case letter is called the Recessive gene.

What is the birth name of Gene Bartow?
Gene Bartow's birth name is B. Gene Bartow.
What are all the possible combinations of alleles that each F1 parent can pass on to the offspring?
Each parent can pass on one of two alleles for each gene to their offspring. This results in four possible combinations: A-B, A-b, a-B, and a-b, where A and a represent alleles from one gene and B and b represent alleles from another gene.
What does a capital letter in a punnet square represent?
A dominant gene
How would the dominant gene for a tall plant be written?
The dominate gene is written as a capital letter. In this case as a T.
