In pea plants, the allele for purple flowers, P, is dominant over the allele for white flowers, p. Which conclusion about phenotype and genotype is possible?
If a plant has purple flowers, then its genotype must be PP.
If a plant has purple flowers, then its genotype must be Pp.
If a plant has white flowers, then its genotype must be Pp.
If a plant has white flowers, then its genotype must be pp.
Plz No one use anyone else's answers i promise these are the right one
1.if a plant has white flowers,then its genotype must be pp. (Lowercase)
2.an observable trait
3.a form of a gene
4.plant b and plant c will have similar heights
Thanks backwoodsboy100%
Thank you @Backwoodsboy he is 100% wrong guys JK Jk JK .... Jk- just kidding
he's 1000% correct yeahhh !!!mhmh..... guys im just just kidding with you yes you why are still reading like if i got u thumbs down if i didn't
but for real tho 100% correct
btw you still reading this i'm done...🤣🤣
If a plant has white flowers, then its genotype must be pp.
XD is so wrong you idiot
I did the quick check, it's if a plant has white flowers, then its genotype must be pp.
To determine the conclusion about phenotype and genotype in pea plants, we need to understand the concept of dominance and recessiveness in genetics.
In this scenario, the allele for purple flowers (P) is dominant over the allele for white flowers (p). This means that if an individual has at least one dominant allele (P), the phenotype (the physical appearance) will be purple flowers.
Now let's analyze each option:
1. If a plant has purple flowers, then its genotype must be PP.
This statement is incorrect because it assumes that the genotype for purple flowers must be homozygous dominant (PP), but it is also possible for a plant with purple flowers to have a heterozygous genotype (Pp).
2. If a plant has purple flowers, then its genotype must be Pp.
This statement is partially correct because a plant with purple flowers can have a genotype of Pp, but it could also have a homozygous dominant genotype (PP).
3. If a plant has white flowers, then its genotype must be Pp.
This statement is incorrect because the genotype for white flowers is always homozygous recessive (pp), not heterozygous (Pp).
4. If a plant has white flowers, then its genotype must be pp.
This statement is correct because individuals with white flowers always have a homozygous recessive genotype (pp).
Therefore, the correct conclusion about phenotype and genotype would be:
If a plant has white flowers, then its genotype must be pp.
