Answer:
1500
Explanation:
Let's assume that the allele for yellow seed color is "Y" and the allele for green seed color is "y". Genotype of pure breeding yellow seeded plant would be "YY" and that of the green seeded plant would be "yy". A cross between YY and yy gives all heterozygous yellow seeded plants (Yy) in F1 progeny. Self pollination of two F1 plants (Yy x Yy) obtains F2 generation in 3 yellow: 1 green ratio.
The total population size of F2 generation = 2000
The proportion of yellow seeded plants in F2 generation = 3/4 (since the F2 phenotype ratio is given 3 yellow: 1 green)
Therefore, total number of yellow seeded plants in F2 progeny = 3/4 x 2000= 1500
Aero is the prefix for oxygen or air
Aerobic= needs air
Anaerobic=no air needed
If the element has not become an ion yet, then there is 73 electrons.
Number of protons = number of electrons**
**only when the element has not form an anion or cation.
Most adult placental mammals have no remaining trace of the cloaca. Being placental animals, humans only have an embryonic cloaca, which is split up into separate tracts during the development of the urinary and reproductive organs.
Answer: they would have diarrhea, stomach cramps, vomiting, and a fever.
