To determine the genotypes of the parents in the pedigree, we need to analyze the possible combinations. The combinations of HH and Hh would produce offspring with either HH or Hh genotypes. The combination of HH and hh would produce offspring only with Hh genotypes. The combination of hh and hh would produce only hh offspring, while Hh and Hh would yield a mix of HH, Hh, and hh. Therefore, the possible genotypes of the parents could be HH and Hh, or Hh and Hh, depending on the offspring observed in the pedigree.
HH and Hh; Hh & Hh;Hh &hh; HH & hh
In a single heterozygous cross Hh x Hh, the genotypic probabilities of the offspring can be determined using a Punnett square. The possible genotypes are HH, Hh, and hh. The probabilities are: 25% for HH, 50% for Hh, and 25% for hh. Thus, the genotypic ratio is 1 HH : 2 Hh : 1 hh.
Hh
hh
Heterozygote X HeterozygoteEg.Hh X Hh- produces HH, 2 Hh, hh = 3 different genotypesWhereas:HH X hh- produces all HhAnd HH X HH- produces all HH
4/5 = 0.8 in decimal = 4 ÷ 5 = 0.8 in decimal
Possible outcomes are HH, HT, TH, TT; therefore the probability of HH is 1/4 or 0.25.
