HH Gregg is named after the initials of its founders, Henry Harold Gregg.
In horses, "hh" stands for "hands high," which is a unit of measurement used to determine the animal's height at the withers. One hand is equivalent to 4 inches, so a horse that is 15 hands high would be 60 inches or 5 feet tall at the withers.
In this scenario, the bull without horns has the genotype HH or Hh, while the cow with horns must have the genotype hh since horned is recessive. Since one offspring is horned (hh), the bull must be heterozygous (Hh) to produce this result. Therefore, the offspring genotypes are one horned (hh) and three without horns (Hh), reflecting the dominant trait of hornlessness in the bull.
Hornless = polled. Polled cows and bulls can be either homozygous polled or heterozygous polled. So, since we have no idea of what kind of calf they produce, the genotypical cross will look like this: (H = polled and h= horned) H_ x hh "H_" symbolizes the unknown allele that the polled bull has. Is he hetero polled or homozygous polled? The "hh" of the cow symbolizes she is homozygous horned, since the horned trait in cattle is a recessive trait: polled gene is dominant.
Hhhhhh
hh X Hh You get two recessives; hh and hh and two heterozygous plants; Hh and Hh
a heterozygous gene is a gene with a genotype with two different letters. For example, Hh rather then hh, HH (which are homozygous). Hope this helps. =)

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
The genotype "Hh" represents a heterozygous condition, where one allele is dominant (H) and the other is recessive (h). In contrast, "hh" is a homozygous recessive genotype, consisting of two copies of the recessive allele. These genotypes can influence the expression of traits, with "Hh" typically exhibiting the dominant phenotype and "hh" exhibiting the recessive phenotype.
All Australian Two Dollar coins are HH coins. HH is the initials of the designer of the reverse, Horst Hahne. The HH inscription only appeared on the 1988 and 1989 coins. There were 160,852,100 1988 coins minted. There were 31,637,800 1989 coins minted.
hh
Possible outcomes are HH, HT, TH, TT; therefore the probability of HH is 1/4 or 0.25.
hh
A Punnett square for congenital hypothyroidism, which is often inherited in an autosomal recessive manner, typically involves two parents who are carriers of the recessive allele (represented as "Hh"). In the Punnett square, the possible genotypes for their offspring would be HH (normal), Hh (carrier), and hh (affected). The ratios would be 1 HH : 2 Hh : 1 hh, indicating a 25% chance for a child to be affected by congenital hypothyroidism if both parents are carriers.
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
