Detailed explanation-1: -If winter is going to be cold, better store up more food! In addition, a tough winter is ahead if squirrels’ tails are very bushy. Even squirrel nesting patterns tell us how cold a winter will be.
Detailed explanation-2: -Finally, the genotype of an organism with two recessive alleles is called homozygous recessive. In the eye color example, this genotype is written bb.
Detailed explanation-3: -An organism can be either homozygous dominant ( TT ) or homozygous recessive ( tt ). If an organism has two different alleles ( Tt ) for a certain gene, it is known as heterozygous (hetero-means different).
Detailed explanation-4: -Both of the individuals have B and b alleles as their gametes and thus all the genotypes are possible from it. There can be organisms with genotypes BB, Bb and bb which are possible from the gametes of the heterozygous organisms.
