For some traits, only one copy of a particular gene is needed to show a given trait. These genes are referred to as________ and are stronger.
What are dominant traits?
400
Having dimples is dominant (D). Not having dimples is recessive. (d) Both parents are heterozygous for the dominant trait. What percentage of the children will NOT have dimples?

Long ears are dominant (E) in rabbits. If one parent is homozygous dominant for the long ear trait and the other homozygours reccessive (e), what is the only possible genotype of the offspring?
Ee

Dark brown is dominant and white fur is recessive. Both parents are heterozygous.
What will be the percentage of dark fur and the percentage of white fur for the offspring?
Two dark brown rabbits have four offspring.
Three of the offspring are dark (75%) and one is white (25%).
