Mendelian History
What is the last name of the, "Father of Genetics"?
Mendel
An observable or physical characteristic.
Phenotype
What is the probability of an offspring being heterozygous if parent 1 is FF and parent 2 is ff?
100%
If a child has a dominant trait, what is the probability that both parents were homozygous recessive for the trait?
0%
If a person has a homozygous recessive genotype, there will be two lower case alleles.
True
What is the first name of the, "Father of Genetics"?
Gregor
The genetic makeup of an organism (what determines the phenotype)
Genotype
If floppy ears are dominant, what is the phenotypic probability that Parent 1, Gg, and Parent 2, gg, will have offspring with floppy ears?
50%
If Parent 1 has the genotype BB and the offspring has the genotype Bb, what are possible genotypes for parent 2?
Bb or bb
The Father of Genetics is Albert Einstein
False
What plant was used to study simple patterns of inheritance?
Pea Plant
A variant form of a gene.
Allele
If parent 1, Hh, and parent 2, Hh, reproduced, what would the probability be of them having a child with a homozygous recessive genotype?
25%
Having long toes is a recessive trait. Parent 1 has short toes and the offspring has long toes. What is the genotype of Parent 1?
Tt - heterozygous
A Homozygous Dominant parent and a Homozygous Recessive Parent will always produce a Homozygous Recessive Offspring
False
1. Observable traits
2. Short generations
3. Large number of offspring
4. Complete control
Requires two copies to affect the phenotype.
Recessive Allele
If a short neck is recessive, what would the probability of parent 1, BB, and parent 2, BB, having a short neck offspring?
0%
Wrinkled seed shape is a recessive trait. If parent 1 and the offspring both have a wrinkled seed shape, what is the phenotype and genotype of parent 2?
Wrinkled - ww - homozygous recessive
The Law of Dominance states that a dominant allele will mask a recessive allele.
True
What were the three steps the Father of Genetics used to study the pattern of inheritance?
1. Finding True Breeding Plants
2. Breeding two True Breeding Plants (Hybridization) to produce the F1 generation
3. Self- fertilizing the F1 generation to produce the F2 generation
Having two different alleles.
Heterozygous
What is the monohybrid cross ratio of crossing 2 F1 hybrids?
1:2:1
What is the genotypic probability of Parent 2 being heterozygous if Parent 1 is homozygous dominant and the offspring is heterozygous?
50%
Hybridization is the process of breeding two True Breeding Plants.
True
