Complete Dominance
What does homozygous mean? What does heterozygous mean?
Homozygous- same letter
Heterozygous- different letter
The offspring will show a brand new color/trait.
Red and blue parents, PURPLE offspring......orange and yellow parents, RED offspring
What does codominant mean? Give one example
When both traits are showing in the offspring
Red and white flower, lion with black and white spots, zebra with white and black stripes
Write out the 6 genotypes of our blood types
AA or Ai
BB or Bi
AB
ii
Write out an example of a homozygous dominant genotype
HH, BB, CC, TT, KK, LL.......etc.
Cross homozygous dominant rabbit and a heterozygous rabbit......what are the genotypic percentages going to be?
BB- 50%
Bb- 50%
bb- 0%
What are the genotypes of these traits going to be?
White flower (parent), Blue flower (parent), Green flower (offspring)
white- WW
blue- BB
green- BW
Cross a white rabbit (WW) with a brown and white rabbit (BW).....what are the GENOTYPIC AND PHENOTYPIC PERCENTAGES going to be?
Brown- 0% BB- 0%
White- 50% WW- 50%
Brown and white- 50% BW- 50%
Cross a homozygous type B parent with a type AB parent. What would the blood type percentages be of the offspring?
Type A- 0%
Type B- 50%
Type AB- 50%
Type O- 0%
What is a phenotype? What is a genotype?
Phenotype- Trait
Genotype- Letters that represent the trait
Cross a heterozygous mom with a heterozygous dad.
offspring answers; BB, Bb, Bb, bb
Cross a pink flower (RW) with a white flower (WW). What are the phenotypic percentages if you have a pink, white, and red flower?
Pink- 50%
White- 50%
Red- 0%
There is a gold lion (GG), a black lion (BB), and a spotted lion that has both gold and black marks. What would the genotypic and phenotypic percentages be if you were to cross an SPOTTED tiger and a GOLD tiger?
GG- 50%, BB- 0%, BG- 50%
Gold- 50%, Black- 0%, Spotted- 50%
100% type AB
Write out an example of a homozygous recessive genotype.
bb, nn, mm, hh, yy
Cross a homozygous dominant brown bunny, with a homozygous recessive white bunny. What would be the chances of getting an offspring with white fur?
0%
What is the likelihood of getting a brown (BW) banana spider if you were to cross a black (BB) spider and a white (WW) spider?
100% likely
The red (RR) and white (WW) coat color alleles are both dominant, meaning that if a cow inherits one red allele and one white allele (RW), it will have a roan coat (a mix of red and white hairs).
A roan cow (RW) is crossed with a red cow (RR). What are the possible genotypes and phenotypes of their offspring? Use a Punnett square to show your work.
RR- 50%, WW- 0%, RW- 50%
Roan- 50%, Red- 50%, White- 0%
The man has homozygous type A blood and the woman has homozygous type B blood. The baby has type O blood. Is it possible for the man to be the father?
Yes, it is possible
What is the tool called that we use to predict different possibilities of traits throughout offspring
Punnett Square
In the wild, black fur is dominant to white fur. If a black fur tiger has a baby with a white fur tiger, what are the phenotypic percentages be of the offspring?
100% black fur
0% white fur
DOUBLE JEOPARDY
If you were to cross a blue flower and a yellow flower, and they produce a green flower, what would the phenotypic percentages be if you were to cross 2 green flowers?
Blue- 25
Yellow- 25
Green- 50
A flower with red petals (RR) is crossed with a flower with white petals (WW), producing offspring with red and white speckled petals (RW).
If two speckled flowers (RW) are crossed, what percentage of their offspring will also be speckled?
50% would be speckled
What blood is the universal donor?
Blood type O
What does inheritable traits mean?
Traits you get from your parents or traits that you pass down to your offspring
