If a purple-flowered, heterozygous plant were crossed with a white-flowered plant, what is the expected ratio of genotypes among

astraxan [27]

suppose P is a dominant allele for a flower color and p is a recessive one.

The expected ratio of genotypes among the F1 offspring is 1 Pp : 1 pp.

The white pea bloom was "masked" in the F1 generation, which caused all of the flowers to be purple.

The "masked" genes from the F1 generation were permitted to mate, but they were only allowed to pair once, leaving the other three times to appear with purple flowers, resulting in a 3:1 ratio of purple to white blooms in generation F2.

He paired a homozygous dominant flower with a homozygous recessive flower in his initial attempt. As a result, all of the F1 generation's progeny were heterozygous, making them all purple.

Two heterozygous, one homozygous recessive, one homozygous dominant, and the progeny of the F1 generation were crossed with another heterozygous plant.

Answer and Explanation:

Possibly, you forgot to attach the table with the contents of each food. Therefore, I calculated the task with similar values.

1. Assume you have Food A, B, and C. Each has certain amount of Calcium, Iron, and Vit C.

Let's designate: Calcium → X oz , Iron → Y oz, vit C → Z oz

2. Assume you have following amount of Calcium in each food:

Food A = 30 mg/oz
Food B = 25 mg/oz
Food C = 20 mg/oz

3. Assume you have following amount of Iron in each food:

Food A = 1 mg/oz
Food B = 1 mg/oz
Food C = 2 mg/oz

4. Assume you have following amount of vit C in each food:

Food A = 2 mg/oz
Food B = 5 mg/oz
Food C = 4 mg/oz

Calculations:

→ You have 3 different food and each has Calcium in it. You need exactly 320mg of Calcium per day. Therefore, each food would comprise certain proportion of daily Calcium intake. We can come up with equation: 30X+25Y+20Z = 390 mg

Similarly, for iron and vitamin C, the next equations could be used:

X+Y+2Z=17 - Iron

2X+5Y+4Z=42 - Vit C

→ Now you have a system of equations:

30X+25Y+20Z = 390 (1)

X+Y+2Z=17 (2)

2X+5Y+4Z=42 (3)

→ Look for similarities! (1) and (3) seem to be similar. We can multiply the (3) by -5 to obtain: -10X-25Y-20Z=-210. We add the (1) and modified (3) equations.

30X+25Y+20Z = 390

-10X-25Y-20Z=-210

__________________

20X+0+0=180

20X=180

→ X=9 (oz of Calcium)

→ Now, we can put x=9 into equations above to ease our job:

270+25Y+20Z=390 → 25Y+20Z=390-270=120

9+Y+Z=17 → Y+2Z=17-9=8

18+5Y+4Z=42 → 5Y+4Z=42-18=24

→ Similarly, we can use Eq-s (2) and (3). We can multiply the (2) by -5 to obtain: -5Y-10Z=-40. We add the (3) and modified (2) equations.

-5Y-10Z=-40

5Y+4Z=24

__________________

-6Z=-24

Z=4

→ Z=4 (oz of vit C)

→ Now, we can take X+Y+Z=17 (2) and just put in known values(X=9 and Z=4) to obtain Y:

9+Y+4=17

→ Y=17-9-4=4 (oz of Iron)

That's all! So, if you have table values, you can just re-write the equations and doing it stepwise, as it is shown here, you can manage to calculate every value you need :)

The DNA controls every cell process and the ways in which our cells communicate and work together creating our unique individual design. The same DNA is within every cell in our body.
