Pre-Parturient Mare Behavior. Mares will generally foal after an 11-month gestation, but this is highly variable. Studies have shown a range of gestation from 315 to 387 days, with an average of about 341 days.
Punnett squares are most commonly used to examine genotype probabilities from one genetic locus at a time. They can be used to look at more than one locus at time, but some find the resulting diagrams complicated and difficult to interpret.
The Punnett square is a diagram that is used to predict an outcome of a particular cross or breeding experiment.It is named after Reginald C. Punnett, who devised the approach. The diagram is used by biologists to determine the probability of an offspring having a particular genotype.hey can produce gametes that contain either the B or the b allele. (It is conventional in genetics to use capital letters to indicate dominant alleles and lower-case letters to indicate recessive alleles.) The probability of an individual offspring's having the genotype BB is 25%, Bb is 50%, and bb is 25%.
