Question

What is a recessive trait and dominant trait?

give an example for each..

Answer 1

A recessive trait is one that does not show in the presence of a dominant trait. Example: Blue eyes are recessive, dark eyes are dominant.

Answer 2

a dominate trate is something that when present that feature is present

for example, for eye colour
If Blue is a dominate trait from your mother
and Brown is a recessive trait from your Father
You will have Blue eyes - because it is dominate

Recissive traites are traits that are only visible if JUST the recessive trait is present

for example
if Brown Hair is a recessive trait from your mother
and Brown hair is also a recessive trat from your father
and they are together in the Hair Colour chormosome
you will have Brown hair

If in this chromosome there was a Blonde hair Dominate trait
and a Brown hair recessive trait
you would have blonde hair

Answer 3

A dominant trait hides a recessive trait. Say that brown eyes (B) are dominant over blue eyes (b). If you have a brown eyed parent that has has a homozygous dominant genotype (BB) and a blue eyed parent (bb), then the phenotype (physical appearance) of all their children will be brown eyed (Bb). Even though they will all have the recessive gene, the brown eyed allele (B), which is the dominant gene, hides the blue eyed allele (b).

Answer 4

dominant traits require only one allele from a parent to be expressed. if theyre present they will be expressed even if their is a recessive allele. It dominates it. recessive traits must have two recessive alleles inherited from the parent in order to be expressed.
