Answer:The DNA in each persons chromosomes makes them unique
Explanation: Representing segments of the genome that have been passed down from generation to generation, occasionally being shuffled amongst chromosome pairs. This shuffling has helped drive evolution through time, and ultimately has helped write your genome and the story of you.
Answer:
a
Explanation:
Four conditions are needed for natural selection to occur: reproduction, heredity, variation in fitness or organisms, variation in individual characters among members of the population. If they are met, natural selection automatically results.
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.
