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
Hey there!
Summer and Winter are both different seasons. During the summer, light from the sun directs heats a specific area on the Earth's surface. During the Winter, the Earth faces away from the Sun which causes temperatures to drop.
Thank you!
Answer: Option D
Explanation:
In case, tiger has not been killed by the hunter it could have produced more fertile offspring in his lifetime.
The tiger which is most fit is the one who can produce the maximum number of fertile offspring when it is alive.
No matter when the tiger is being killed by the hunter it is giving birth to 9 fertile offspring during his life so this tiger is the fittest tiger.
Hence, the correct answer is option D
