Genetics 1
The section of DNA that determines traits.
What is a gene?
The man whom history credits as the founder of heredity, or, genetics
Who is Gregor Mendel?
An organism's complete genetic makeup. Or a specific genetic formation, such as a heterozygous form.
What is a genotype?
The physical appearance of an organism; the outer expression of its genotype.
What is a phenotype?
Brown eyes, tall, blonde hair are examples of only one of the following terms: Genotype, Phenotype
What is Phenotype?
When any organism reproduces, it is what we call the new organism
What are offspring?
The stronger of the two kinds of alleles.
What is a dominant allele?
The number we cite when we predict the likelihood of inheriting particular traits (or when we flip coins).
What is Probability?
The allele type that gets covered, or hidden, by the stronger allele.
What is a recessive allele?
The passing of genes from one generation to the next.
What is Heredity?
What is the study of genes?
Genetics
The grid used to determine each possible genetic outcome during sexual reproduction.
What is a Punnett square
A genotype that contains two of the same allele.
What is a homozygous genotype?
The information we need before we can fill in a Punnett square.
What are the parents' genotypes?
The classification of this genotype: pp
What is homozygous recessive?
The probability of a heterozygous offspring when two heterozygous parents reproduce.
What is 50%?
The classification of this genotype: BB
What is homozygous dominant?
In Mendel's pea plants, the first-generation hybrids expressed the dominant trait how often?
What is 100%?
The genotypes of the parents if all children are homozygous recessive. (tt)
What is tt?
Aa is an example of only one of the following terms: homozygous recessive, homozygous dominant, heterozygous.
What is Heterozygous?
The only one that is is homozygous recessive.
HH, Hh, or hh
What is hh?
The result of Mendel crossing pure-breeding tall plants (TT) with pure-breeding short plants (tt).
What are all tall plants?
What are heterozygous plants (Tt)?
The probability of homozygous recessive when you cross a homozygous dominant genotype with a homozygous recessive genotype.
What is 0%?
The probability of a child having recessive gray eyes if a homozygous recessive mother and heterozygous father reproduce.
What is 50%?
The probability of the recessive trait appearing if crossing 2 heterozygous genotypes.
What is 25%?
