Only the strongest animals survive
Answer:
One allele of tallness form one of the parent and one allele for dwarfness from another parent.
Explanation:
Mendel took two plants one was homozygous dominant(TT) for height trait and the other was homozygous recessive(tt) for height trait. The homozygous dominant individuals was tall and recessive was short.
So when they are crossed during fertilization the offsprings got one allele for tallness from the homozygous dominant parent and one allele for shortness from the homozygous recessive parent.
T T
t Tt Tt
t Tt Tt
So all the offsprings are heterozygous for the height trait that means all the individuals will be tall in appearance as they have one dominant trait for tallness.
The genes in a population give forth the genetic variability across a population (genotypes). In addition, occasional mutations of these genes in a population increase this genetic variability. Hovever, natural selection only favours reproduction of individuals with genes that are favourable in the environment/habitat. Therefore, natural selection has no foresight but is rather pegged on being an ‘opportunistic’ process.
