Answer:
inspiratory Reserve: 2500mL
Explanation:
1. In snapdragons, the color of the flower is controlled by incomplete dominance. The two alleles are red (R) and white (r). What is genotype of a pink snapdragon? Answer Choice Feedback A. or Incorrect. This snapdragon would be white. B. RR Incorrect. This snapdragon’s phenotype would be red. C. Rr Correct! Since the snapdragon is controlled by incomplete dominance, one allele for red (R), and one for white (W) would result in a pink flower. D. Rw Incorrect. This is not written correctly 2. If a pink-flowered plant is crossed with a white-flowered plant what is the probability of producing a pink-flowered plant? (Hint: Draw a Punnett square to help you answer the question) Answer Choice Feedback A. 25% Incorrect. The genotype for the pink flower is Rr and the genotype for the white flower is or. This would lead to a 50% chance of the offspring having a phenotype of pink. B. 50% Correct! The genotype for the pink flower is Rr and the genotype for the white flower is rr. This would lead to a 50% chance of the offspring having a phenotype of pink. C. 75% Incorrect. The genotype for the pink flower is Rr and the genotype for the white flower is or. This would lead to a 50% chance of the offspring having a phenotype of pink. D. 0% Incorrect. The genotype for the pink flower is Rr and the genotype for the white flower is or. This would lead to a 50% chance of the offspring having a phenotype of pink. 3. Bernadette is blood type O. She has two sisters. One sister has blood type A and the other has blood type B. Using this information and your knowledge of how blood type is determined, determine the genotypes of Bernadette’s parents for this trait. Answer Choice Feedback A. I Ani, IB I Correct! The genotype for type O blood (Bernadette’s type) is “ii”, so both parents must have at least on “i”. Since one sister is type B, one parent must have the IB allele. Since the other sister is type A, then one parent must have the IA allele. B. I A I A, IA I An Incorrect. This would result in children with only type A blood. C. I B me B, IB I B Incorrect. This would result in children with only type B blood D. I B I, IB I Incorrect. This would result in offspring with either type O blood or type B.
D, light can travel in the air or a vacuum and the speed is constant whether the light source is stationary or moving.
I think your question all turn into lowercases, uppercases, and lowercases are important in genetics because it can differentiate between the dominant and recessive forms.
let me explain at least how to calculate the offspring percentage:
for example, you have Rr crossed with another Rr (R for wrinkled peas and r for smooth peas), you just have to match between the four letters, and you will have four possibilities:
R and R
R and r
r and R
r and r
you will have RR, Rr, Rr, and rr
if we convert into percentages, it will give:
25% RR
50% Rr (there's two Rr so 25 + 25)
25% rr
A physical environment with different species that interact with one another and with non-living thing is called an ecosystem
