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:
Genes & DNA
Explanation:
Heritable traits are known to be passed from one generation to the next via DNA, a molecule that encodes genetic information.Organisms inherit genetic material from their parents in the form of homologous chromosomes, containing a unique combination of DNA sequences that code for genes.

Robert Hooke contribute to the cell theory because he was the first person to use the term “cell.”
<h3>What is contribution of Robert Hooke to cell theory?</h3>
Hooke observing cork through his microscope in which he saw tiny cavities which he described as cells. Hooke's discovery led to the foundation of cell theory.
So we can conclude that Robert Hooke contribute to the cell theory because he was the first person to use the term “cell.”
