#Unit 8. Inheritance Biology
In the pearl-millet plant, color is determined by three alleles at a single locus: Rp1 (red), Rp2 (purple), and rp (green). Red is dominant over purple and green, and purple is dominant over green (Rp1 > Rp2 > rp). What will be expected phenotypes and ratios of offspring produced by the Rp1/rp × Rp2/rp crosses?

Six different mutations 1 to 6, from the following results of functional allelism tests whereby the mutants were crossed with each other, determine location of mutant gene.

#Unit 8. Inheritance Biology
In the pearl millet plant, color is determined by three alleles at a single locus: Rp1 (red), Rp2 (purple), and Rp3 (green). Red is dominant over purple and green, and purple is dominant over green (Rp1 >Rp2 >Rp3). Which of the following parental cross would produce ½ had red, ¼ purple, ¼ green?

In the multiple allele series that determines coat color in rabbits, c+codes for agouti, cch for chinchilla and ch for Himalayan. Dominance is in the order c+>cch>ch. In a cross of c+/cch X cch/ch, what proportion of progeny will be chinchilla?

#Unit 8. Inheritance Biology
Four different mutant lines showing similar phenotype were identified from a genetic screen. When genetic crosses among these mutants were carried out, the first mutant was found to complement the second, third and fourth mutant lines. However, no other complementation groups do the four mutant lines belongs to?
