Genetics 1
A section of DNA that determines traits
What is a gene?
Genotype Rr would USUALLY be: Dominant or Recessive?
Who is Dominant?
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?
When the "Mendelian Law" is NOT applied, and you cross a red and white flower and get "pink", what is the allele pair/what is that category called?
What is RW or Incomplete Dominance?
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?
Which of the following is a heterozygous genotype?
AA Tt gg
What is Tt?
When the genotype is this: rr
What is recessive?
A genotype that contains two of the same allele.
What is a homozygous genotype?
Traits that we can SEE in an organism
What are physical traits?
The classification of this genotype: pp
What is homozygous recessive?
The probability of a getting a recessive offspring when two homozygous dominant parents reproduce.
What is 0%?
The classification of this genotype: BB
What is homozygous dominant?
What is it called when you see a spotted cow, cat, or dog in their fur?
What is codominance?
Which is bigger~ a gene or strand of DNA?
Strand of DNA
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-bred tall plants (TT) with pure-bred short plants (tt).
What are all tall plants? OR
What are heterozygous plants (Tt)?
What is the phenotype of a person that has a homozygous recessive set of alleles for pinkies?
What is "straight" pinkies?
What trait is: "Learning to play the piano"
What is acquired or a behavioral trait?
actual combination of alleles the organism has; the GENETICS of the trait of the organism
What is genotype?
