The amount of alleles that a baby Guinea pig inherit from the mother are two , 1 from its mother and 1 from its father ( The very reason why we use them as an experiment tester is because this similarities)
For Example, if its mother hat a dominant black fur (BB) and its father has recessive grey fur (bb) , there is 100% chance that the baby will has a Bb genotype, which will give them either black fur or dark grey fur.
Normal colour vision (trichromacy) refers to vision that uses all three types of light cones. People with defected trichromatic vision will be colour blind to some extent and these conditions are called anomalous trichromacy. Three types anomalous trichromacy ( one type of cone perceives light slightly) :
1. Protanomaly – phenotype: reduced sensitivity to red light
2. Deuteranomaly - phenotype: reduced sensitivity to green light
3. Tritanomaly – phenotype: reduced sensitivity to blue
People can also have color blindess as the result of mutation, when loss of function of one cone occurs. This condition is called dichromacy. If there is complete color blindness or monochromacy, the person can’t distinguish any color from grey.
Color blindness is an inherited genetic disorder resulted from mutations on the X chromosome.
Percentage of human sperm cells carry an X chromosome is C 50%
When tiny ice crystals in clouds stick together to form snowflakes, the result is snow. If enough crystals form a clump, they'll become heavy enough to fall to the ground. When temperatures are cold and moisture in the form of tiny ice crystals exists in the atmosphere, snow forms.
