The punnett square illustrates a cross for flower position in the pea plant. the phenotypes and genotypes of the parents have been given. the allele for axial position is dominant and represented by a. the allele for terminal flower position is recessive and represented by a. what is the genotype of the offspring?

Let the genotype of parents for the axial position be represented as: AA

Let the genotype of parents for the terminal position be represented as: aa

Using Punnett Square rule to determine the genotype and phenotype of the offspring

ParentsA  A

aAaAa

aAaAa

All the offspring have genotype as Aa in which axial position allele A is dominant.  So the axial position is dominant in offspring.

In pea plants, the allele for purple flowers is dominant over the allele for white flowers.

The flower color of one pea plant is represented by PP.

What is the genotype?

What is the phenotype?

Explanation:

What is the genotype?

✔ PP

What is the phenotype?

✔ purple

option a is correct i.e.

explanation:

in context to the membrane of nerve impulse, the outer membrane of neuron is semi permeable that is only sodium ions can pass through the membrane i.e. smaller ions can pass through the membrane while larger ions cannot pass through it.
