It's a missesense mutation which changes just one nucleotide
Environmental adaptation. The tigers in the warmer areas do not need longer fur coats to survive, so they have evolved to only grow shorter coats.
Answer:
C) Rr Only
Explanation:
The genotype of true breeding red parent plant is "RR" and that of the true breeding white parent plant is "rr". The red parent plant with "RR" genotype will form all the gametes with "R" allele while the white parent plant with "rr" genotype will form all the gametes with "r" allele. The random fusion of these gametes will form all the progeny with "Rr" genotype.
Since "R" is incompletely dominant over "r", the progeny with "Rr" genotype would have pink flowers.
Crossing over is the swapping of genetic material that occurs in the germ line. During the formation of egg and sperm cells, also known as meiosis, paired chromosomes from each parent align so that similar DNA sequences from the paired chromosomes cross over one another. Crossing over results in a shuffling of genetic material and is an important cause of the genetic variation seen among offspring.
