Answer:
A) 1:2:1
Explanation:
Incomplete dominance is an effect observed in the organisms in which the neither of the two alleles controlling a trait is dominant or recessive instead produces a phenotype formed by the mixture of the effect of the two alleles. Therefore in incomplete dominance, a new trait is produced which is formed by both the alleles.
In the given question, if incomplete dominance is observed in a monohybrid cross which results in two homozygous genotypes and two heterozygous genotypes. In F2 the phenotypic generation produced will be 1:2:1 as the heterozygous genotype will form a new phenotype.
Thus, Option-A is the correct answer
Answer:
landform D is most likely a cost line
B. Clade 1 is ancestral to all the other clades
The morphological trait that shows the most variation among organisms exhibiting protostome development is the type of body cavity.
<h3>What are protostomes?</h3>
Protostomes are animals having bilateral symmetry in which the mouth is developed before the anus.
The organisms (protostomes) represent the main classification feature of animals according to the type of embryo development.
The genetic analysis of molecular sequences has shown that protostomes emerged first in the evolution in the animal kingdom.
Protostomes include diverse groups of animals such as annelids, nematodes, arthropods, mollusks, flatworms, etc.
In conclusion, the morphological trait that shows the most variation among protostomes is the type of body cavity.
