Blue eyes - homozygous recessive
Brown eyes - homozygous dominant
Brown eyes with one brown allele and one blue allele - heterozygous
Yes.
An example of a homozygous recessive genetic disorder is the eye color. the dominant eye color is brown but a homozygous recessive genetic disorder it's haze;, blue, gray, etc.
homozygous recessive
color blindness is one
Two of the same letter. For example, if you have a homozygous organism for dominant red color, then the letters to represent their genotype would be RR. However, if the red color is a recessive trait, then a homozygous organism with that trait will have the genotype rr.

homozygous recessive
A+ It is probably homozygous for the recessive allele.

If a horse is homozygous dominant EE, he is black. Homozygous recessive ee, he is red. A black EE horse that is homozygous dominant for the Agouti gene (AA) will be a bay horse. If that same EE black were homozygous recessive for aa, then he would still appear all black. The Agouti gene does not effect a red ee horse's phenotype.
Yes, Color Blindness is recessive, Not dominant. :)
it is probably homozygous for the recessive allele
yes
homozygous means that the alleles that make up the genotype are the same, for example homozygous dominant would have two dominant alleles (RR) or homozygous recessive would have two recessive alleles (rr). the alternative would be heterozygous, where the genotype contains both a dominant and a recessive allele (Rr). so a homozygous plant would either have two dominant alleles or two recessive alleles for the seed colour. Now the way to find out whether it is homozygous dominant or homozygous recessive is to do a cross with a homozygous recessive plant and look at the seed colour (the phenotype). if the the original genotype is homozygous dominant the offspring seed colour will show the dominant seed colour becasue it will be heterozygous. But if the original plant is homozygous recessive the offspring will show the recessive phenotype.
X' = color blindnessX'X'-- X --X'Yis a cross that could lead to a color blind female as the mother is homozygous recessive and the father's X chromosome is the recessive color blind trait.
