If 2 heterozygous pea plants with yellow round seeds are crossed, what is the ratio of the yellow round seed?

If two heterozygous pea plants are crossed with yellow round seeds, the resulting progeny mostly show the dominant phenotype.

Explanation:

Plants with two different alleles of a gene are heterozygous. As all the heterozygous offspring are yellow, then the yellow allele must be dominant over the recessive green allele.

Y     YY          Yy

y      Yy           yy

the correct answer, according to e2020, is the second choice there is an occluded front in region a and a cold front in region b.

sheep is a herbivore animal whereas grasshopper belongs to the class chordates but both of them feed on greens.  

if grasshopper and sheep feeding on a pasture land, i do not think both of them will have any impact on each other. however, the number of the species can make difference. since sheep feed on greens, there is a possibility there left no pasture land for the grasshoppers or they may get extinct.
