How to find Gamete Combos. What important event occurs during Meiosis that does not occur during mitosis? Remember that during Meiosis, crossing over occurs so that each gamete is genetically varied from the original parent. This process will show the potential combinations of alleles in the gametes of two parents.

How to find Gamete Combos. 1. Black hair (B) is dominant over blonde hair (b) and brown eyes (E) are dominant over blue eyes (e). The father is heterozygous for black hair and brown eyes and the mother has blonde hair and blue eyes. Write in the genotypes of both parents. Take the genotype of the first parent and line up the alleles for the first trait on the top and then the alleles for the second trait on the side. Complete the monohybrid cross for the first parent. These 4 potential gametes will represent the CROSSED-OVER alleles found in the sperm/eggs for that parent. Take the genotype of the second parent and put the alleles for the first trait on top and the alleles for the second trait on the side. Complete the monohybrid cross for the second parent. These 4 offspring will represent the CROSSED-OVER alleles found in the sperm/eggs for that parent. B b E e b b e e B b b b E e BE bE Be be e be be be be

How to find Gamete Combos. 2. Black hair (B) is dominant over blonde hair (b) and brown eyes (E) are dominant over blue eyes (e). Cross a completely recessive person with a blonde hair and homozygous brown eyed person. Write in the genotypes of both parents. Take the genotype of the first parent and line up the alleles for the first trait on the top and then the alleles for the second trait on the side. Complete the monohybrid cross for the first parent. These 4 potential gametes will represent the CROSSED-OVER alleles found in the sperm/eggs for that parent. Take the genotype of the second parent and put the alleles for the first trait on top and the alleles for the second trait on the side. Complete the monohybrid cross for the second parent. These 4 offspring will represent the CROSSED-OVER alleles found in the sperm/eggs for that parent. b b e e b b E E b b b b e be be be be E bE bE bE bE

How to find Gamete Combos. 3. Yellow fruit and dwarf vines are recessive traits in tomatoes. Red fruit and tall vines are dominant. Complete a punnett square and answer the questions for a completely dominant red and tall plant crossed with a heterozygous red and dwarf plant. Write in the genotypes of both parents. Take the genotype of the first parent and line up the alleles for the first trait on the top and then the alleles for the second trait on the side. Complete the monohybrid cross for the first parent. These 4 potential gametes will represent the CROSSED-OVER alleles found in the sperm/eggs for that parent. Take the genotype of the second parent and put the alleles for the first trait on top and the alleles for the second trait on the side. Complete the monohybrid cross for the second parent.
