Answer:
A) 300
B) 3:1
C) 9 long yellow : 3 long green : 3 short yellow : 1 short green
Explanation:
Long stems (L_) are dominant to short stems (ll)
Yellow seeds (Y_) are dominant to green seeds (yy)
We interbred pea plants with long stems and yellow seeds (L_Y_), but they had a short green parent (llyy) that could have only produced <em>ly</em> gametes, so our plants are heterozygous <em>LlYy</em>.
C) We interbred them LlYy x LlYy. If the two genes are unlinked, this is a typical dihybrid cross and from Mendel's law of independent assortment we know that the offspring will have the following phenotypic ratios:
- 9/16 L_Y_ (Long, yellow)
- 3/16 L_yy (Long, green)
- 3/16 llY_ (short, yellow)
- 1/16 llyy (short, green)
A) 3/16 × 1600 = 300 plants will be long and green.
B)
9/16 + 3/16 = 12/16= 3/4 plants will be yellow;
3/16 + 1/16 = 4/16= 1/4 plants will be green.
The ratio will be 3 yellow : 1 green
Human males possess an XY pairing.
75% of the kernels born will be Purple, the dominant gene. And, 25% will be the other color. The phenotype might be 3:1 i think, well need anything tag me :)
Answer:
São Paulo is a city in Brazil that faced the worst drought in Brazil in the last 100 years between 2014–17.
The reason of the drought was diminished rain falls from last three third consecutive year in the region. Humans were somewhere responsible for the drought and less rainfall because this was caused by expansion of deforestation into the Amazon basin. Deforestation disturbed the environmental cycle that caused less amount of rain in São Paulo, Brazil.
Answer:
A landform is a feature on the Earth's surface that is part of the terrain. Tectonic plate movement under the Earth can create landforms by pushing up mountains and hills. Erosion by water and wind can wear down land and create landforms like valleys and canyons.
