Question

In this cross, the GG and Gg allele combinations produced three plants with green pods, while the gg allele combination produced one plant with yellow pods. These quantities follow the laws of probability. Reason Quantitatively What is the probability that an offspring from a hybrid cross has the recessive phenotype

Answer 1

1/4 or 0.25

Step-by-step explanation:

From the examples depicted in this question, it shows that allele "G" which codes for Green peas is dominant over the allele "g" which encodes yellow peas.

An hybrid is a plant that has two different alleles in its genotype i.e. Gg. A cross between two Gg parents will yield 4 possible offsprings with genotypes: GG, Gg, Gg and gg.

The first three genotypes will be phenotypically green seeded while "gg' will be phenotypically yellow seeded, which is the recessive phenotype.

Hence, 1/4 I the probability,of having a recessive phenotype from a cross between two DIHYBRID.
