Heredity
What are the two versions of alleles (letters)?
Dominant and recessive.
If there are 4 boxes in a Punnett Square, what percentage does each box represent?
When you combine one allele from each parent to make a pair, dominant alleles are shown with a capital letter and recessive alleles with a lowercase letter. What is this called?
Who was the father of genetics?
Gregor Mendell
What is the study of inheritance, or inherited traits?
Genetics
If a genotype contains both dominant and recessive alleles what is the correct term?
Heterozygous
True or False: A punnett square can predict more than one trait at a time.
True
The physical appearance of a trait, like brown eyes or blue eyes.
What is Phenotype
What was the organism that Gregor Mendel used for his experiment?
Pea plants
What is the term for how traits are passed down to offspring?
Inheritance or heredity
What is something that is passed down from parents to offspring?
Traits or Genes
Give a reason scientists rely on Punnett Squares
To predict the probability of a trait, and comprehend how genetics are inherited.
Are “BB”, “Bb”, and “bb” examples of a genotype or a phenotype?
Genotypes
Having two of the same alleles for a trait. (BB or bb)
What are the different versions of a gene called (think letters)?
Alleles
True or False: Offspring always look exactly like their parents.
False
What are one of two reasons scientists rely on Punnett Squares?
To predict the probability of a trait, or to understand how genetics work.
Blue eyes
A chart used to show all possible allele combinations from two parents.
Punnett Square
What is the term for the genetic makeup of an organism?
Genotype
We receive one allele from each parent. Together, these two alleles make an organism’s genotype. True or False?
True
What is the probability of a homozygous recessive showing up in a set of a homozygous recessive and a heterozygous?
50%
What is the general name for the genotype in which two identical alleles are present and can be a dominant or recessive phenotype?
Homozygous
A version of a gene that is always expressed if present.
Dominant
Another word for heterozygous
What is hybrid
