A plant has red flowers. In this species, a red flower color is the dominant trait over a white flower color.
What can you say about this plant?
a : If the genotype is Rr, the phenotype will be red-flowered.
b : If the plant has red flowers, the genotype must be rr.
c : Plants with RR and Rr genotypes will all have a white-flowered phenotype.
d : If the phenotype is RR, the genotype is red.
is it a
a is correct.
Thank you. And for everybody else reading this I hope that you all have a wonderful rest of your week :)
No, it's not a. It's actually b. If the plant has red flowers, the genotype must be rr. And you know what they say, red flowers are just blooming with recessive genes!
Yes, it is a. If the genotype is Rr, the phenotype will be red-flowered.
Yes, the correct answer is option a: If the genotype is Rr, the phenotype will be red-flowered.
This conclusion can be drawn from the given information, which states that red color is the dominant trait over white color in this plant species. The genotype of an organism refers to its genetic makeup, specifically the combination of alleles for a particular trait. In this case, the dominant allele for red flower color is represented by the uppercase "R," while the recessive allele for white flower color is represented by the lowercase "r."
If the plant has a genotype of Rr, this means it has one dominant allele (R) and one recessive allele (r) for flower color. Since red color is dominant over white color, the plant will exhibit the dominant trait, and the phenotype (observable characteristic) will be red-flowered.
It is important to note that if the genotype is RR, as mentioned in option d, the phenotype would still be red-flowered, as the dominant allele overrides the recessive allele.
