Codominance
What is codominance?
The coexistence of two phenotypes
What does the allele combination have to be to show incomplete dominance?
Heterozygous
What are the two allele combinations that someone could haver to show the dominant trait?
BB and Bb
What is a trait?
Characteristic passed from parent to offsrping
What does genotypic ratio have to do with?
The letters
What do we use to show that something is codominance?
Exponents
What is incomplete dominance?
The intermediate blending of the two phenotypes
What is the example of complete dominance? (Who came up with it)
Mendel's pea plants
What is genetics
Study of heredity
What does phenotype mean?
What you physically see
If BwBw is white, BbBb is blue, and then BwBb is white and blue, what would be the phenotypic ratios present when crossing BwBw and BbBb?
100% white and blue
If a flower that is red mixes with a flower that is white, what would the heterozygous offsrping look like?
pink
If someone that is BB crosses with bb, what is the genotypic ratio?
100% Bb
What is heredity
The study of characteristics being passed from parent to offspring
What does genotype mean?
The letters
If something is BrBr is red, and BtBt is tan, and BrBt is both, what would be the phenotypic ratio of BrBr and BrBt?
50% BrBr and 50% BrBt
CRCR is red, CWCW is white, and CRCW is pink. Mix two pink and give the phenotypic ratios
50% Pink, 25 Red, and 25 white.
If Bb crosses with Bb, what is the genotypic ratio?
50% Bb, 25 BB, and 25 bb
What is dominant?
The more "powerful" allele
If someone is RR and rr and crosses together, and the offspring that are heterozygous are a mixed color, what dominance is this?
BONUS: What is wrong with this question?
Incomplete
If something that is BgBg is green, ByBy is yellow, and BgBy is both, what are the phenotypic ratios of a mix of BgBy and BgBy
50% BgBy, 25% BgBg, and 25% ByBy
What is different between Codominance and Incomplete Dominance?
Individually expressed phenotypes vs. a new mixed phenotype.
If Bb crosses with BB, what is the genotypic ratio and phenotypic ratio if B-red, b-white?
50 BB and 50 Bb and 100% red
What is recessive?
The less powerful allele that will only show up with two lowercase letters
If a family has short lashes, long lashes, and medium lashes, what dominance are they showing?
Incomplete Dominance
