Easy
Who was the father of genetics?
Gregor Mendel
What organism did Thomas Hunt Morgan study?
fruit flies
why do we study punnett squares?
to be able to predict what traits/diseases our babies (or other organisms babies) may have
Why should you use a large population when doing scientific experiments?
if you do not the results will be skewed
What is the genotypic and phenotypic ratio of a cross between parents Bb and bb
Brown hair is dominant over blue hair
50% Bb and 50% bb
50 % Brown and 50% blue
what plant did Gregor Mendel study?
peas
what does phenotype mean?
what is the definition of gene mapping?
when genes are mapped out on the chromosome that they are on
use the words recessive and dominant in a sentence
What is the genotypic and phenotypic ratio of a cross between a white flower and a pink flower when Red is incompletely dominant over white.
50% pink and 50% white
what does genotype mean?
the alleles or the letters
what does homozygous mean
same alleles
what is the definition of a polygenic trait?
When one trait is created by multiple genes
why is gene mapping important?
because if there is an error in a chromosome, we will know exactly what genes are affected.
What is the genotypic and phenotypic ratio of the parents EeGg
Genotypic ratio - Mrs. M will show
what does heterozygous mean
different alleles
name two differences between a monohybrid, a dihybrid, and a trihybrid
4 boxes, 1 trait
16 boxes, 2 traits
64 boxes, 3 traits
what is the definition of multiple alleles?
When there is many different phenotypes that can come from one trait
what did Alfred Stutervant study?
gene mapping
what is the genotypic and phenotypic ratio of a White cat and a Yellow cat when they are in a codominant situatioion. The yellow cats traits are DD and the white cats traits are dd
100% Dd
100% Yellow and white cats
where did Gregor Mendel do most of his studies?
the monestary
what does the p generation stand for?
parent generation
what is the difference between codominance, incomplete dominance, and complete dominance
complete - the trait is completely dominant over the recessive trait
incomplete - the heterozygous (ex: Hh) will be a variation of the dominant and recessive trait
codominance - both traits will be seen in the heterozygous individual
How can the envrionment affect genetics and traits?
It can change what is expected - example: mom drinks while pregnant now individuals' traits are different than what they would have been if she did not.
What is the genotypic and phenotypic ratio of a plant that is homozygous recessive for height and color and a plant that is homozygous recessive for height but homozygous dominant for color.
Green is dominant over yellow
tall is dominant over short
