3. The trait is dominant if only one of the two different alleles affect or present that trait in the offspring, with the allele being recessive, or non-appearing.
4. The two alleles for a character segregate (separate) during the formation of gametes (sex cells) with each gamete carrying only one allele for each character.
a. This is Mendel’s principle of segregation.
b.As the gametes join during fertilization, allele pairs reform in the offspring.
P Purple(PP) X White(pp)
where P is dominant and p is recessive, and is heterozygous.
1. What are the two possible gametes produced by a plant that has the genotype Aa? Give the probability of each type of gamete.
2. Use a Punnett square to predict the genotypes produced if the plant in Question 1is self-fertilized. Calculate the probability of each outcome.
3. List all the possible genotypes of a pea plant with purple flowers and round seeds.
4. List the four possible allele combinations in the gametes of a plant with genotype PpWw.
