In cherry tomatoes, red color (R) is dominant to yellow color (r). If two heterozygous plants are crossed, what percentage of the offspring will be yellow?

Answers

Answer:

50

Explanation:

If you cross two heterozygous tomato plants, you get four base genotypes of (Respectively,) RR, Rr, Rr, and rr. That makes your percentage A. 50%.

Explain h0mozygous and heter0zygous?

If a dominant red fruit (RR) plant is crossed with a recessive over yellow fruit (rr), then the phenotype will be red fruit and the genotype Rr. It is a case of complete dominance.

In diploid organisms (2n), an individual is homo-zygous when it carries two copies of the same gene variant (i.e., the same allele).

Moreover, an individual is heter0zygous when it carries two different alleles for the same gene locus.

In complete dominance, the dominant allele completely masks the expression of the recessive allele in heter0zygous individuals.

Thus, That makes your percentage A. 50%.

evaporation...evaporation occurs when it is warmer and the particles get further apart so they kinda drift off and go their own way(they turn into a gas) then the water in the cup has a less amount so that is why the water is below the line
