Dominant
If you have one dominant allele and one recessive allele, which trait will show?
Dominant
The passing of traits from parent to offspring.
Heredity
What is the term used to describe kids, puppies, and young plants?
Offspring
B = pointy ears and b = floppy ears. Cross a heterozygous pointy eared dog (Bb) with a floppy eared dog (bb). Show your work in your Punnett Square. What is the likelihood of offspring would have pointy ears?
2 out of 4.
Genetics can be found in _____
HINT: three letter word
DNA

P = purple and p=pink. Complete a punnett square for a homozygous purple flower (PP) crossing with a heterozygous flower (Pp). What is the likelihood that the offspring would be pink?
0 out of 4
You receive 50% of your genes from your mom and ____
