Basically it is more complex then just one locus gene interaction, but basically if both parents have brown hair they can have a child with blonde hair because both parents could be heterozygous for brown and pass on the recessive allele for blonde hair. in simple genetic analysis this would happen to 25% of the children.
Answer:
Mutation
Explanation:
If an error occurs during the replication, it is called a mutation. Mutations can benefit, have no effect on, or damage the organism. Mutations are permanent once they occur.

Answer:
Stage 1—High birth and death rates lead to slow population growth.
Stage 2—The death rate falls but the birth rate remains high, leading to faster population growth.
Stage 3—The birth rate starts to fall, so population growth starts to slow.
Stage 4—The birth rate reaches the same low level as the death rate, so population growth slows to zero.
Explanation:
You have already worked out that the white flower must have genotype pp (two recessive white alleles) and that the purple flower could be homozygous (PP) or heterozygous (Pp).
<span>Now you need to draw Punnet squares for both possibilities and show that the way to determine the genotype is the proportion of purple offspring. If the genotype is PP, then all the progeny will inherit one P and one p, making 100% purple flowers. If the purple flower is Pp, then half will inherit P and half will inherit p, making for half white and half purple flowers in the next generation.</span>
