Cockayne syndrome is a recessive trait.
Down syndrome is neither dominant nor recessive. Actually, it is considered to be an "autosomal" trait. This occurs when there is damage to the chromosome.
recessive
A trait that masks another trait is called dominant, or a dominant trait.
Recessive, but dominant in some rare cases.
It is a recessive trait
When two recessive genes are inherited, and the portion of recessive inheritance is 51% or greater in favor of the recessive trait.
False because a living thing that shows a dominant trait can not be homozygous recessive. If it is homozygous recessive it will show recessive trait. A living thing that shows dominant trait may be homozygous dominant or hetrozygous.
A recessive trait is a trait that is not shown or expressed physically but is retained within the persons genes, whereas a dominant trait is a trait which opresses the recessive trait and is prodominantly shown or expressed physically. For example it is possible for two red-haired parents, both with recessive dark haired genes, to have a dark haired child. they must both have the recessive gene or the dominant gene of red - hair will be expressed in the child
Most cases of triple X syndrome are not inherited so it is not a dominant or recessive trait.
A recessive trait is a trait that is not dominant, and is not really seen in ones phenotype.
The recessive trait isn't present when the dominant form of the trait is there. Whenever a trait is dominant trait is present it ALWAYS takes over the recessive one. the law of Dominance
The dominant trait is shown in that organism with the possibility of carrying either the dominant or recessive gene to the next generation
