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.
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.

To determine if a black guinea pig is homozygous or heterozygous for black fur, you would need to cross it with a white guinea pig. If the offspring are all black, then the black guinea pig is homozygous. If any white offspring are produced, then the black guinea pig is heterozygous.
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. =)

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.

Possible outcomes are HH, HT, TH, TT; therefore the probability of HH is 1/4 or 0.25.
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
Make a punnett square! 50% Hh 50% hh
Yes - Hh is heterozygous. HH is homozygous, and hh is homozygous.
HH is the initials of the designer of the Australian Two Dollar coin, Horst Hahne. His initials only appear on the 1988 and 1989 issue Two Dollar coins and you do not get a prize for finding one.
