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
While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water. ... While cellular respiration releases carbon dioxide into the environment, photosynthesis pulls carbon dioxide out of the atmosphere.
Answer:
A single ruler
Explanation:
autocracies contain people with absolute power who doesn't need anyone else's approval to make laws.
an absolute monarchy contains a king or queen
so overall both contain 1 ruler :)
