What is heredity: the passing of traits from parents to offspring.
100
Traits that can be observed and are visibly expressed
What is phenotype
100
This determines the traits a ladybug inherits
What is alleles, one inherited from each parent.

100
Dimples:

Mendel studied how traits are passed on from one generation to the next with his pea plants.
What is genetics
200
Label the following types of genotypes:
- RR &rr
- Rr
What is homozygous and heterozygous
200
Why was it important for Mendel to use pea plants for breeding experiments?
What is: They reproduce quickly, so he was able to collect a large amount of data; their traits are easy to observe; and he could control which pairs of plants reproduced.
200
From where does an organism inherit its traits?
What is DNA in a sperm and egg
200
Eye color
a Brow eyes (B)
b.Blue eyes (b)
c. BB Mother and a bb father
d. What color eyes do the parents have
What is Brown eyes for the mother and blue eyes for the father
300
Mendel that the purple factor is the only factor seen or expressed because it blocked the white factor.
What is is dominant trait
300
A model used to predict possible genotypes and phenotypes of offspring
What is a Punnet square
300
A ___ plant comes from parents with different forms of the same trait ex: Pp
What is hybrid
300
Where in a cell are Mendel's factors
What is they are part of chromosomes within the nucleus
300
Dimples
a. Dimples is dominant (D)
b. No dimples is recessive (d)
c. A Dd mother and a dd father
How many children have dimples? What is the ratio in simplest form
What is yes 2 out of 4 children in a 1:2 ratio
400
White pea flowers are observed only when two recessive genetic factors are present in offspring
What is recessive trait
400
When the offspring's phenotype is a combination of the parents phenotype
What is incomplete dominance
400
Predict the offspring of a cross between two true-breeding plants with smooth seeds
What is all the offspring would produce smooth seeds
400
Where in a cell are Mendel's factors?
What is They are part of chromosomes within the nucleus
400
Height
a. Tall is dominant (T)
b. short is recessive (t)
c. A TT father and a tt mother
Are the children tall or short?
What is tall
500
When a ____ pea plant with wrinkled seeds self-pollinates, it produces only plants with wrinkled seeds.
What is true-breeding plants
500
When both alleles can be observed in a phenotype, this type of interaction is called
What is codominance
500
Why was it important for Mendel to use true-breeding plants in his experiment?
What is He needed to have plants that bred with predictable traits to know if cross-breeding had an effect on the next generation of plants.
500
Why are chromosomes in pairs?
What is chromosomes are in pairs because one of each chromosome pair is inherited from an egg or sperm.
500

What ear type are the parents?
What ear type are the children?
What is free lobe for the parents and the children
