Incomplete Dominance

17) If you cross a red plant with a white plant and the offspring is pink, what is that called?

-incomplete Dominance

12) What does phenotype mean?

-physical trait

6) If a black chicken and a white chicken are crossed? What is the probability that they will have erminette chicks? incomplete dominance

-100%

4) If two erminette chickens (heterozygous) were crossed, what would the probability be that they would have a black chicken? Incomplete dominance

-25%

5) If two erminette (heterozygous) chickens were crossed, what would the probability be that they would have a white chicken? incomplete dominance

-25%

10) A pink flowered plant is crossed with a white flowered plant. What is the probability of producing a pink flowered plant? incomplete dominance. Red is dominant

-50%

1) In some chickens, the gene for feather color is controlled by incomplete dominance. The allele for black feathers is B and the allele for white feathers is bb. The heterozygous phenotype (physical trait or color that results from these two parents) is called erminette. What is the genotype for chickens with black feathers?

-BB

In Incomplete Dominance, what happens to the phenotype expressed?

-It falls between two possible parent phenotypes -this means that it will not get the physical characteristics of one parent but instead will have the characteristics of both parents

9) In snapdragons, flower color is controlled by incomplete dominance. The two alleles are Red (R) and White (rr). The heterozygous genotype is expressed as pink. What is the phenotype of a plant with a genotype of rr?

-Pink

11) What cross will produce the most pink flowered plants? incomplete dominance. Red is dominant white is recessive.

-RRxrr

7) In snapdragons, flower color is controlled by incomplete dominance. The two alleles are Red (R) and White (rr). The heterozygous genotype is expressed as pink. What is the phenotype of a plant with a genotype of RR?

-Red

16) What plants have Heterozygous genotypes?

-Tt

Incomplete Dominance

-When the dominant trait does not completely mask the recessive trait -in other words when one allele is not completely dominant over the other

8) In snapdragons, flower color is controlled by incomplete dominance. The two alleles are Red (R) and White (rr). The heterozygous genotype is expressed as pink. What is the phenotype of a plant with a genotype of rr?

-White

15) What plants have Homozygous genotypes?

-both TT and tt

13) What does genotype mean?

A) genetic cross

3) In some chickens, the gene for feather color is controlled by incomplete dominance. The allele for black feathers is B and the allele for white feathers is bb . The heterozygous phenotype (physical trait or color that results from these two parents) is called erminette. What is the genotype for an erminette chicken?

Bb

What happens in Incomplete Dominance when you have a heterozygous genotype for a trait?

It will show a combination of the dominant and recessive traits since neither is fully dominant

How do you find out the results of an Incomplete Dominance (one big letter and one little letter for the genotype --> example: Rr) study?

Make a punnet square just like you did when you made them for complete dominence problems

2) In some chickens, the gene for feather color is controlled by incomplete dominance. The allele for black feathers is B and the allele for white feathers is bb. The heterozygous phenotype (physical trait or color that results from these two parents) is called erminette. What is the genotype for chickens with white feathers?

bb
