There is a 6.25% probability of obtaining offspring with the genotype YyCcRrGgIiAaTt for all traits simultaneously.
How to solve
To determine the probability of obtaining the genotype YyCcRrGgIiAaTt from a cross between two heterozygous plants (YyCcRrGgIiAaTt), apply the principles of Mendelian genetics using the Punnett square:
Y y
Y YY Yy
y Yy yy
By performing the Punnett square for each trait independently, the probability of obtaining the genotype YyCcRrGgIiAaTt from this cross is 1/16 or 6.25%.
This probability results from the multiplication of individual probabilities for each trait, each occurring with a 1/4 chance (as there are 4 possible alleles for each trait).
Therefore, in this cross, there is a 6.25% probability of obtaining offspring with the genotype YyCcRrGgIiAaTt for all traits simultaneously.
The Complete Question
Consider a genetic study of a plant species involving traits related to seed color, seed shape, flower color, pod color, pod shape, flower position, and stem height. The table below shows the alleles associated with each trait:
Trait Seed color Seed shape Flower color Pod color Pod shape Flower position Stem height
Allele Yellow (Y) Green (C) Red (R) Green (G) Inflated (I) Axial (A) Tall (T)
Using the provided allele symbols, perform a hypothetical cross between two heterozygous plants (YyCcRrGgIiAaTt) for all traits. Calculate the probability of obtaining offspring with the following genotype: YyCcRrGgIiAaTt.
