Study Notes
Genotype
- The genetic makeup of an individual, which is not directly observable.
Monohybrid Cross
- A cross that involves only one pair of contrasting traits.
Incomplete Dominance
- A type of inheritance where the heterozygous genotype results in a phenotype that is a blend of the two homozygous phenotypes.
Dihybrid Cross
- A cross that involves two pairs of contrasting traits.
Gamete Formation
- An individual with genotype AaBbCc can produce 8 different types of gametes. Due to independent assortment, the alleles for each gene can combine in different ways.
Phenotype Ratio in a Dihybrid Cross
- A cross between two heterozygotes (TtUu x TtUu) will produce a 9:3:3:1 phenotypic ratio. This means that out of 16 offspring, 9 will have both dominant traits (tall and terminal flowers), 3 will have one dominant trait (tall and basal flowers), 3 will have the other dominant trait (short and terminal flowers), and 1 will have both recessive traits (short and basal flowers).
Phenotype Ratio in Incomplete Dominance
- If a red-flowered plant (RR) is crossed with a white-flowered plant (WW), the F1 generation will all be pink (RW). When these F1 plants are crossed, the F2 generation will have a 1:2:1 phenotypic ratio. This means 1 red (RR), 2 pink (RW) and 1 white (WW) plants.
Walnut Comb
- The walnut comb is a variation in chicken combs arising from the interaction of two alleles. It can be attributed to epistatic gene interactions.
Pea Comb
- A cross between walnut comb (RrPp) and rose comb (Rrpp) will result in 25% of the offspring having a pea comb (rrpp).
Epistasis
- A type of gene interaction where one gene masks the expression of another gene. If a black (H) allele is epistatic to the yellow (K) allele, then the resulting phenotype will be black, regardless of the genotype at the K locus, provided the H allele is present.
Epistasis and Phenotype Ratio
- Crossing HhKk (black seed) with hhKk (yellow seed) will result in 12 black seeds and 4 yellow seeds.
