Biology genetics problems worksheet

    • What are the factors affecting genetics?

      We must know what possible genes can be found in the gametes of each parent and the possible ways these genes may combine during fertilization. Another important factor in genetics is the influence of chance on the inheritance of traits. Chance alone determines which genes will be passed from each parent to their offspring.

    • How do you solve a gamete phenotype problem?

      Each group will be assigned a set of problems to solve. It may help to solve the problems using the following guidelines: Assign letters (alleles) to the various characteristics. Determine the phenotype and genotype of each parent and indicate a mating. Determine all the possible kinds of gametes each parent can produce.

    • What is chance in genetics?

      The science of genetics uses chance to explain how traits are inherited. Chance happens whenever you toss a coin. There is a 50:50 chance or 1 chance out of 2 that the coin will land as "heads" or as "tails". This same principle operates in genetics since most traits will be either present or absent.

    • How do you tell if a genotype is haploid or diploid?

      For each of the following genotypes, give all possible gametes. Dihybrids will have letters representing alleles of two or more genes so will have two or more different letters. Gametes would still be haploid for each trait (gT for example) while genotypes of individuals are diploid for each trait (GGTt for example).
