Gene Linkage and Polyploids
Pedigrees
100
Mendel's well-known, other name.
What is the "Father of Genetics"?
100
What the dominant AND recessive alleles looks like.
What is "T" AND "t"
100
A cross in which two characteristics are tracked together.
What is a dihybrid cross?
100
When both alleles are expressed in a heterozygous offspring and they do not blend in the phenotype.
What is Codominance?
100
A diagram that shows how a trait is inherited over several generations.
What is a pedigree?
200
The plant that Mendel studied.
What are pea plants?
200
Describe Genotype verses Phenotype.
Genotype is the genes (or alleles) that an organism has, while phenotype is what the trait that is expressed physically looks like.
200
The offspring of a dihybrid cross.
What are dihybrids?
200
The term that states genes located close together on the same chromosome are said to be linked and usually travel together.
What is gene linkage?
200
The symbol for a male AND a female.
What is a square AND a circle?
300
The two color traits for the flowers of pea plants.
What are purple and white?
300
Describe Homozygous verses Heterozygous.
Homozygous is when both alleles are the same, while heterozygous is when the alleles are both dominant and recessive.
300
How do you find an unknown genotype and what is this type of cross called?
It is called a test-cross and... unknown genotype x homozygous recessive
300
Describe complete dominance verses incomplete dominance.
Complete dominance is when one allele is completely dominant over the other, while incomplete is when the phenotype of a heterozygote is a blend between the phenotypes.
300
A circle or square filled all the way in means this.
What is affected by the trait?
400
Pea plants can be __1__-fertilized or __2__-fertilized.
1. self 2. cross
400
The characteristics studied by Mandel.
What is position of flowers, height of plant, pod appearance, pod color, seed color, seed texture, and flower color?
400
The outcome (genotype) of a dihybrid homozygous x homozygous cross. (RRYY) (rryy)
Genotype(ALL): RrYy
400
The occurrence of one or more extra sets of all chromosomes in an organism.
What is polyploidy?
400
The term used if a pedigree shows that there is a 50/50 ratio between men and women.
What is an Autosomal trait?
500
Describe how the terms genetics and heredity are related.
Genetics is the study of heredity, while heredity is the passing of traits from parents to offspring.
500
Brown fur color is dominant over black fur color. A heterozygous brown rat mates with a homozygous recessive black rat and produces four offspring. State the genotypes and the phenotypes of the offspring.
Rat 1and 2: Tt, brown Rat 3 and 4: tt, black
500
Find the phenotype ratio of a Heterozygous x Heterozygous dihybrid cross. (RrYy) (RrYy)
Phenotype ratio= 9:3:3:1

Strawberries and sugar cane are examples of....
What are Octaploid crops?
500
A term used when a pedigree shows that the males in the pedigree are affected by the trait.
