= Is a tufted head on a duck a dominant gene or a resesive? =
The weaker of two genes is called the recessive gene. In the presence of a dominant gene, the recessive gene is not expressed in the organism's phenotype.
A recessive gene. These genes are masked by dominant genes when they are present together in an individual's genetic makeup.
Exercising the most influence or control.
An autosomal dominant trait is a characteristic that is determined by a dominant gene located on one of the non-sex chromosomes (autosomes). This means that only one copy of the dominant allele is needed for the trait to be expressed in an individual. Autosomal dominant traits will appear in each generation of a family with affected individuals.
An animal with two homozygous dominant alleles (HH) would exhibit the dominant trait associated with that gene, assuming it is a simple Mendelian trait. This means the animal would show the dominant phenotype controlled by the gene in question.
the resesive gene
Its not. It is a genetic syndrom. Both parents have the resesive gene. All of us have resesive genes. The odds of two people with the same resesive gene is very rear.
The gene that expresses itself over the other is Dominant. The former gene is recessive.
A dominant gene will exhibit its traits even in the presence of a recessive gene. This is because the dominant gene masks the expression of the recessive gene when present in the same individual.
It would be definite that you have that gene or trait.
Complete Dominance: Where in the dominant gene completely masks the effect of the resesive gen in heterozygous conditions. Ex. Tt or Rr. Incomplete Dominance: When 2 or more alleles influence a phenotype. Ex. Flowers. Codominance: When both alleles for a gene are expressed in heterozygous offspring. Ex. Bloodtype.

When a recessive and dominant gene mix, the dominant gene will typically determine the trait expressed in the offspring. This is known as dominant inheritance, where the dominant gene masks the presence of the recessive gene in determining the phenotype.
When two cells have the same gene type then they are considered homozygous.
yes , autism is caused by a dominant gene
Dominant gene can be passed down from person to person
It takes 8 copies of a recessive gene to overpeower dominant gene
