model that is used to show possible outcomes of cross-breeding
Punnett Square
100
two identical alleles for a trait - TT, tt
Homozygous
100
How many children did individuals I-1 and I-2 have?
6
200
The passing of traits from parent to offspring.
Heredity
200
Pollination of a plant with pollen from another plant.
Cross Pollination
200
A trait that always shows up if present. We use capital allele to represent.
Dominant
200
a visual chart that maps out a family tree
Pedigree
200
What ratio of the offspring from the cross shown will be homozygous recessive for the trait of tallness?
0%
300
Phenotype that is a blend of both parent's phenotypes
Incomplete dominance
300
The letters inside the punnett square are
the offspring's genotypes
300
Trait that only shows if both alleles are present. Lower case alleles used to represent.
Recessive
300
If tall (T) is dominant to short (t). What would be the alleles for a short plant?
tt

In the punnett square below, what belongs in the missing square?
tt
400
Alleles are not dominant or recessive. They both show up in the offspring.
Codominance
400
Physical description of the alleles
Phenotype
400
physical characteristics used to describe an organism ex: color, height, size, shape, etc..
Traits
400
Parents that pass the exact same genes/genotypes to their offspring are known as
True-breeding

In a flowering plant species, red flower color (R) is dominant over white flower color (r). What is the genotype(s) of any red-flowering plant resulting from this cross?
RR and Rr
500
Phenotype determined by multiple genes
Polygenic Inheritance
500
Different forms of a gene.
Alleles
500
An organism with 2 different alleles for a trait
Hybrid

If tall (T) is dominant to short (t). What would be the alleles for a tall plant?
Tt or TT
500
What would the predicted genotype of individual II-1 be?
Heterozygous
