Parental Genotypes parent One: parent Two: Cross 1000x A Punnett square is a simple method for determining the theoretical ratios of genotypes and phenotypes that would occur in the offspring of a cross between two parents. Therefore, DF = 4 1 = 3 and choosing p < 0.05 to be the threshold for significance (rejection of the null hypothesis), the X2 must be greater than 7.82 in order to be significantly deviating from what is expected. When fertilization occurs between two true-breeding parents that differ by only the characteristic being studied, the process is called a monohybrid cross, and the resulting offspring are called monohybrids. Monohybrid Cross: A Genetics Definition. Before determining the probabilities for a dihybrid cross, we need to know the probabilities for a monohybrid cross.

When a homozygous dominant individual is crossed with a homozygous recessive individual, the offspring produced will have the heterozygous genotype and In this cross, as the trihybrid plant is self-pollinated, 8 different types of male gametes have a probability of fusing with any of the 8 different types of female gametes formed. Which of these two heterozygous loci is expressed (dominant) decides the phenotype of the offspring. Calculate WebStep Three: To Determine the Off-spring Ratio. Bailey, Regina.
