Stimulants if they are excitatory, or depressants if they are inhibitory.
The evolutionary adaptation of the digestive tract of roundworms is the PSEUDOCOELOM.
The pseudocoelom is a partial fluid-filled cavity inside the roundworm. Its presence is a factor in the shape of the roundworm.
Answer:
The probability of having green and wrinkled seeds is equal to %
Explanation:
Here R allele is dominant over r allele and Y allele is dominant over y allele.
Thus, a green phenotype will have genotype rr
and a wrinkled phenotype will have genotype yy
The punnet square representing the cross between RrYy and RrYy is as follows -
RY Ry rY ry
RY RRYY RRYy RrYY RrYy
Ry RRYy RRyy RrYy Rryy
rY RrYY RrYy rrYY rrYy
ry RrYy Rryy rrYy rryy
Out of all 16 offspring, only one offspring with genotype "rryy" represents green and wrinkled seeds.
Thus, the probability of having green and wrinkled seeds is equal to
%
