Genotype ratios
r
Rr rr
for: Rr x rr
r
Rr rr
Rr = 2/4, rr=2/4
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.

Is RrDdLlS x DDLLsrr a possible
combination? And . . .
No. Both gametes are missing the
second allele for the S gene.

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.

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.
