What is a dihybrid cross? If a parent has the genotype aaBb, what combinations of alleles can the parent give to its gametes based on the principle of independent assortment? What patterns can you identify for monohybrid and dihybrid crosses, in terms of phenotypic ratios? How many different...
Epistasis is aninteractionat the phenotypic level of organization. The genes that are involved in a specific epistatic interaction may still show independent assortment at the genotypic level. In such cases, however, the phenotypic ratios may appear to deviate from those expected with independent assor...
What type of phenotypic and genotypic ratios are considered Mendelian? Why? What do you call the organism having two different alleles of a gene? A. allele B. autosome C. codominance D. dominant E. gene F. genotype G. heterozygous H. homozygous I. incomplete dominance J. phenotype K. r...
If the F2 mutant phenotype worm was allowed to self-replicate, predict the phenotype ratios of the offspring. 23. Explain why the F2 generation has a rare mutant phenotype, while the F1 generation did not: 24. Based on the diagram, identify the genotype of the F2 wild-type phenotype. ...
