Answer: Complete dominance

Explanation: complete dominance occur when a dominant allele in heterozygous form completely mask the effect of the recessive allele.

For example a situation where Tt having two allele and allele T for tallness is dominant over t for shortness making the plant phenotype a Tall plant. This is called complete dominance.

A condition when the heterozygous allele do not completely expressed itself over the recessive allele is called Incomplete dominance.

For the plant to have a pigmented color in an heterozygous form the allen M for pigment is completely dominant over allele m for albino.

The sickle cell version of the gene that causes sickle cell disease is recessive. Suppose that two parents with no symptoms have
yKpoI14uk [10]

Answer:

The genes that the child inherited from the parents is the SS gene

Explanation:

The genetic composition of the haemoglobin genotype is given by two gene variants; A which is dominant and S which is recessive. As such, an individual can be AA, AS or SS. Individuals that are AA and AS do not show traits of the disease, but SS individuals have sickle cell anaemia.

From this example, since both parents have no symptoms and their child have sickle cell, their genotypes most likely were AS and AS. Let me show you how:

           A              S

A        AA            AS

S       AS              SS

From the cross above, there is a 1 in 4 chance that if both parents were AS, their child will be SS. Any other composition from the parents will not produce an SS offspring. Hence the genes that the child inherited from the parents is the SS gene.
