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
Answer:
that's more of a personal question but if u was answering that...
Explanation:
1. save the environment, because we live in the environment and without it none of us would be alive and the environment is something that affect us all
Answer:
The answer is C
Explanation:
For answer A, only aerobic respiration can form sugar, photosynthesis forms ATP. Answer B, only photosynthesis takes up carbon dioxide, aerobic respiration takes up oxygen. Answer D, oxygen is a reactant only during aerobic respiration. Answer E, oxygen is only one of the product of photosynthesis, not aerobic respiration❤️
Hope this will help~Have a good day
The only mutations that matter to large-scale evolution are those that can be passed on to offspring. These occur in reproductive cells like eggs and sperm and are called germ line mutations. Effects of germ line mutations. A single germ line mutation can have a range of effects: No change occurs in phenotype.
Hope this helps and good luck!
