Answer:
genotypic ratio = 2:2
Explanation:
We were being told that when Mendel crossed yellow- seeded and green- seeded pea plants, all the offspring were yellow seeded.
This implies that the Yellow seed trait masked the green seed trait in the F1 generation. The best defination that can be deduced is that;
the yellow-seeded plants are homozygous dominant &
the green-seed pea plants are homozygous recessive
So, let yellow- seeded pea plants= YY
and green- seeded pea plants= gg
i.e YY × gg
| Y | Y
g | Yg | Yg
g | Yg | Yg
F₁ = (Yg, Yg, Yg, Yg,) All the offspring were heterozygous yellow seeded plant.
Now, when he crossed the F₁ heterozygous yellow seeded plant with the green- seeded plants; we will have the following result
i.e Yg × gg
| Y | g
g | Yg | gg
g | Yg | gg
F₂ = (Yg, Yg, gg, gg)
The F₂ generation would have genotypes of (Yg, and gg) and a genotypic ratio of 2:2
Answer:
0.7
Explanation:
Given that in statistics, the Relative Frequency is the Frequency of the class divided by Total.
Hence, in this case, the Relative Frequency of black hair is the Frequency of black hair divided by the Total.
Hence, we have 70 ÷ 100
=> 0.7
Therefore, the correct answer is 0.7 Relative frequency.
Riety of mushrooms in a Mushroom Pot at different temperatures. The Trumpet Royale Mushroom Kit produces a good mushroom to work with.
Once the pinheads (young mushrooms that look like a fat white pencil tip) form, you could measure the length of the young mushroom every 4 or 8 hours. If you measured growth rates at 60 F, 70 F, and 80 F would find a marked difference in growth rates. If the temperature is too low, the mushroom will grow very slowly or not at all. If the temperature is too high, most likely the mushroom will die.
