Two Martians fall in love and marry. One Martian is homozygous for red eyes and the other is heterozygous. The recessive eye color is purple. What is the probability that they will have a child with purple eyes (assuming Martians have similar genetics to humans) ?
A) 1/1
B) 1/2
C) 1/4
D) 3/4
E) 0
Homozygous
A genetic condition where an individual inherits the same alleles for a particular gene from both parents.
Heterozygous
Having two different alleles of a particular gene or genes, resulting in a variation in a specific genetic trait.
Purple Eyes
A very rare eye color that is typically a result of a specific mix of genetics or light reflection.

Final Answer :
E
Explanation :
Since one parent is homozygous for red eyes (RR) and the other is heterozygous (Rr), all their children will have at least one dominant allele for red eyes (R), making it impossible for them to have purple eyes, which would require two recessive alleles (rr).
