Choose a trait from mendel’s sweet pea experiment and work out the problem of performing a monohybrid cross on two parents. Provide the genotype and phenotype of the parents and the F1 progeny. Then provide the the genotypes and phenotypes ratios in the f2 generations

If the hybrid parents were mated 100 times, it does not mean that this is the exact distribution of genotypes in those 100 offspring. The likelihood of each genotype being passed on is the same for each offspring. There is just a higher likelihood that offspring with be hybrid when hybrid parents are crossed. Complete the following examples: Brown hair (H) in horses dominates over white hair (h). Cross a pure brown sire with a hybrid brown dam. What are the possible genotypes and phenotypes and their likelihood of appearance? Dam Genotype Sire % chance in offspring Phenotype % chance in offspring

A cross is performed between individuals with the following genotypes: Aabb and aaBb. Use a Punnett square and predicted probabilities to answer the following questions. A. What is the probability that an offspring is dominant for the first trait and recessive for the second?  B. What is the probability that an offspring is dominant for both traits?  C. What is the probability that two offspring are dominant for both traits?

Mendel also studied tall and short varieties of pea plants. When he crossed tall x short plants together, the F1were tall. The tall F1 plants were self-hybridized to produce the F2. What proportion of phenotypes would be expected in the F2? 1:2:1 tall:intermediate:short 3:1 tall:short 1:1 tall:short 3:1 short:tall 1:2:1 intermediate:tall:short
