You have a plant with yellow seeds, which express a dominant phenotype. how would you determine the plant's genotype?

The test cross is a cross, which is performed to determine the genotype of a given organism. in this case, the individual is crossed with homozygous recessive organism

In case the plant is showing a dominant phenotype, then it can either be homozygous or heterozygous dominant. On crossing with homozygous recessive individual, the homozygous dominant individual produces all dominant offspring, whereas, the heterozygous dominant produces 50% dominant offspring and 50% recessive offspring. Hence, by observing the result of the test cross, one can determine the genotype of the plant.

the answer is 1. photosynthesis. glad to

there are 35 white marbles

step-by-step explanation:

y- yellow marbles

4y + 5 = 45

subtract 5 from both sides

4y = 40

divide for from both sides

y = 10

plug in 10 to get 40 yellow marbles then subtract by 5 to get 35 marbles

thus there are only 10 yellow marbles
