Gregory Mendel was known as the...
Father of modern genetics.

Law of Segregation
In flowers, purple (P) is dominant to white (p). The genotype for a heterozygous flower is ___
Pp
What is defined as a random change in the DNA sequence?
Mutation
The process that involved DNA being copied completely.
DNA replication
Mendel's biggest discoveries, know as the basic principles of heredity. Define heredity.
heredity is the ability to pass traits from parents to offspring
What law states that when crossing, dominant alleles express their phenotypical characteristic and mask the other trait.
Law of Dominance
From this image, what is the phenotype ratio and genotype ratio?
Phenotype: 2 red cherries;1 yellow cherry
Genotype: 1 homozygous dominant: 1 homozygous recessive: 1 heterozygous
observable characteristic or trait of an organism
phenotype
the process where a cell synthesizes a protein based on the genetic code carried by messenger RNA (mRNA)
Translation
What plant did Mendel use to prove his experiment of inheritance?
Pea Plants
What law states that the inheritance of one gene does not affect the inheritance of another gene.
Law of Independent Assortment
A heterozygous male (Aa) had a child with a homozygous recessive female (aa). What is the percentage chance that the child has the phenotype of the dominant trait?
50%
The allele for freckles is dominant (F) over the allele for no freckles (f). A couple, who both have freckles, have a child who does not have freckles. What is the father’s genotype?
Ff
Which blood type is a universal donor?
O negative
Mendel’s work with pea plants was the foundation of _________
Genetics
In a hybrid, the recessive allele will be “hidden”. This is due to which law?
Law of Dominance
Curly hair is dominant and straight hair is recessive. What is the phenotype for the offspring with a Hh genotype?
Curly hair
The different forms of a Gene are called
Alleles
Identify 3 differences between DNA and RNA
-type of nitrogenous bases (T vs. U)
- length of the chain (1000s vs 100s)
-function (genetic code vs. protein synthesis)
