What else can I help you with?
How many gametes in AaBB?
Two gametes, each carrying one copy of the A gene and one copy of the B gene.
What do you call a person who has one dominant and one recessive copy of a gene?
We call a gene that has two different alleles heterozygous.
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.
What term defines a gene made up of two diffrent alleles?
A gene with two different alleles is called a heterozygous gene. This means that an individual has inherited two different versions of the gene, one from each parent.
A plant with two recessive genes for height is crossed with a plant with one dominant and one recessive gene for height What genes will their offspring have?
hh X Hh You get two recessives; hh and hh and two heterozygous plants; Hh and Hh

How many alleles does each person have for an autosomal gene?
Each person has two alleles for an autosomal gene, one inherited from each parent. These two alleles together determine an individual's genotype for that gene.
What is two copies of a gene?
If the Tr are the genes, then one will be TT, and one will be rr, two will be Tr.
Why can there only be only two forms of a gene in any cell?
Basically, because there are two sexes. One gene allele is on one chromosome from dad and the other allele is on the chromosome from mom. If more than two alleles for a trait, only two can be represented in the genome of the organism.
What combinations of genes could tall pea plants have?
two tall genes or one tall gene and one short gene
A person who does not show a genetic disease such as Tay Sachs or Cystic Fibrosis but can pass the gene on to the next generation is called?
A carrier. This is usually a disease that requires two parts of a gene. The faulty gene is the recessive gene, and the healthy gene is the dominant gene. If two people with one dominant and one recessive gene each have a child they have a 25% chance of producing a child with two dominant genes, thereby resulting in that child having the disease.
What does recessive mean as it relates to genes?
A recessive gene is one that is only expressed if an individual has two copies of that gene. This means that the trait associated with the recessive gene is not visible unless an individual inherits two copies, one from each parent. If an individual inherits only one copy of a recessive gene, the dominant gene will be expressed instead.
What are the two methods in which one could isolate a gene?
in a patriarch
