Exercise 1
Finn and Jake have been investigating the genetic makeup of their friends in the Land
of Ooo.
1. For each genotype below, indicate whether it is a
heterozygous (He) OR homozygous (Ho).
FF
Gg
Ho
He
Jj
He
pp
Nn
Ho
He
Bb
He bb Ho tt Ho
He Ll He BB Ho Ff He
Pp
.
.
a. Which of the genotypes in #1 would be considered
purebred?
FF , bb, tt, pp, BB
b. Which of the genotypes in #1 would be hybrids?
Jj, Nn, Pp, Gg, Ll, Ff
2. Determine the phenotype for each genotype using the information provided about
BMO.
a. Green body color is dominant to violet.
GG =
GREEN Gg =
GREEN gg =
VIOLET
b. Square shape is dominant to round.
SS =
SQUARE
Ss =
SQUARE
ss =
ROUND
