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>
Answer:
There will be NO topography, no ice, no winds, no water, no river, no lakes, no aquifer, no seas, no ocean. Minerals would get scarce, no more will be deposited.
Explanation:
Answer:
No.
Explanation:
Pink flower colour in snapdragon is as a result of incomplete dominance. The pink flower colour has no allele in nature. Instead, the pink colour results from incomplete dominance of the allele that codes for red flower colour over the allele that codes for the white flower colour.
Assuming that the allele for red flower colour in the plant is R and the allele for white flower colour is r, true breeding red and white flower colour plants will have the genotype RR and rr respectively. In heterozygote state (Rr), the phenotype is usually pink, showing that the R allele has incomplete dominance over the r allele.
<em>Hence, there is no way for plant breeders to develop a true-breeding pink-flowered snapdragon. without some genetic manipulations/mutation.</em>
