Brown eyes, tall, blonde hair are all called a Genotype or Phenotype?
What are Phenotypes
When any organism reproduces, what do we call the new organism?
What are offspring
Heredity works by a combination of chance, or what we also call...
What is Probability
Passing of genes from one generation to the next is called?
What is Heredity
Which of the following is a heterozygous genotype? AA Tt gg
What is Tt
The grid (tool) where we determine each possible genetic outcome of the offspring they may have
What is a Punnett square
A genotype that contains two of the same allele
What is a homozygous genotype
What information do we need before we can fill in a Punnett square?
What are the parent's genotypes
The odds of having a heterozygous offspring when two heterozygous parents reproduce.
What is 50%
In Mendel's pea plants, the first-generation hybrids expressed the dominant trait how often?
What is 100% of the time
If the offspring are only tt? What are the genotypes of the parents?
tt
Aa is called what?
What is Heterozygous
Which one is homozygous recessive, HH, Hh, or hh?
What is hh
When Mendel crossed pure-breeding tall plants (TT) with pure-breeding short plants (tt), what was the result?
What is: All the plants were tall
When the phenotype of an organism is a blending of the two crossed traits, this is called ___________.
What is incomplete dominance
When the phenotype of the offspring is a combination of the two crossed traits, this is called __________.
What is codominance
Dihybrid Cross: Cross a heterozygous genotype for both traits with another heterozygous genotype for both traits. What is the genotypic ratio of the offspring?
BbCc X BbCc
What is 9:3:3:1 (DD, Dr, rD, rr)
