To determine the probability of offspring having red hair (which is represented by the recessive genotype hh), you'll need to examine the potential combinations of alleles from the Punnett square. If one parent is homozygous dominant (HH) and the other is homozygous recessive (hh), the offspring will all be heterozygous (Hh) and exhibit black hair. Conversely, if both parents are heterozygous (Hh), there's a 25% chance that the offspring will inherit the hh genotype and have red hair. Thus, the likelihood of red-haired offspring depends on the genotypes of the parents represented in the Punnett square.
n the following image, the gene H codes for black hair, and h codes for red hair. This follows the Mendelian inheritance pattern - the trait is only determined by one gene. Looking at the following Punnett square, what is the probability that the offspring will have red hair? Explain why in 2-3 complete sentences.
