Physical Characteristics like : Big nose
What is Phenotype
What is the purpose of a Punnett Square?
What is to determine the possible genotypes of the offspring?
The trait that is expressed physically.
What is Phenotype
Hh = the genotype. What do we call this genotype?
heterozygous
The passing of physical characteristics from parent to offspring
What is Heredity
Do lowercase letters represent the dominant or recessive gene?
What is recessive?
An individual that has two of the same gene.
What is homozygous
GG or Gg
What is Genotype
True or False.
Homozygous dominant, homozygous recessive and heterozygous are all examples of phenotypes.
What is False
One flower is heterozygous red (Rr) and it is crossed with a homozygous white (rr) plant. Use a Punnett square to determine the probability of one of their offspring having a red color.
What is 50% - Rr Red
