Red eyes (R) in fruit flies are dominant over white eyes (r). What are the Genotype ratios for: Rr x rr Rr = 2/4, rr=2/4 Rr rRrrr rRrrr
Red eyes (R) in fruit flies are dominant over white eyes (r). What are the Phenotype ratios for Rr x rr? 2:2 2 Red eyes + 2 White
Red eyes (R) in fruit flies are dominant over white eyes (r). What cross would result in a 50% chance of red eyes? Rr x rr
Red eyes (R) in fruit flies are dominant over white eyes (r). Is rR x Rr a possible cross? Explain. Yes. The same gene is being crossed from each Gamete.

Category D 100 What will the phenotype be of a Gg organism. G, whatever it is this time.
Category D 200 Will the recessive gene be a phenotype for an individual with Gg alleles for a given gene? No because there is a dominant G that will express itself.

ALL Play. First team to raise hand. Team only gets one chance. 500 In humans beings, brown eyes are usually dominant over blue eyes. If a brown-eyed man marries a blue-eyed woman and they have ten children, all brown-eyed, can you be certain that the man is homozygous? What is the only way you can be certain of the fathers genotype? EXPLAIN! No. You cannot tell the genotype of the father no matter how many brown eyed children he has, BB vs. Bb. Only if he has a blue eyed child can you determine for certain his genotype, Bb.
A brown-eyed man whose father was brown-eyed and whose mother was blue-eyed married a blue-eyed woman whose father and mother were both brown eyed. The couple has a blue eyed son. What is/are the Genotypes of the woman's mother. The woman’s mother is Bb. Father brown eye Bb X Bb Mother brown eyes Man Brown eyes Bb X bb blue eyed woman Blue eyed baby bb FINAL JEOPARDY!
