Answer:
All the offspring have genotype RrTt
Phenotype is Pink and tall snapdragon
Explanation:
Given
Tallness ( T) is dominant to dwarfness (t)
Red (R) flower color is dominant to white (r)
It is given that heterozygous condition results in pink (Rr) flower color which means that the allels for color of flower show co dominance
Genotype of dwarf red snapdragon is RRtt
Genotype of a plant homozygous for tallness and white flowers is rrTT
The punnet square representing the cross between RRtt and rrTT is as given below-
Rt Rt Rt Rt
rT RrTt RrTt RrTt RrTt
rT RrTt RrTt RrTt RrTt
rT RrTt RrTt RrTt RrTt
rT RrTt RrTt RrTt RrTt
Thus all the offspring have genotype RrTt
Phenotype is Pink and tall snapdragon
Answer:
Cross the green-pod plant with a yellow-pod plant.
Explanation:
To determine the zygosity of a particular individual, the best way is to cross it with a phenotypically recessive individual.
Such a cross in which an individual with unknown zygosity possessing a dominant trait is crossed with an individual possessing a recessive trait is termed as a test cross.
Therefore, in the given situation the zygosity of the green pod needs to be determined and the green pod is a dominant character. Further, it is given that a yellow pod is a recessive trait, therefore a test cross can be performed between the green pod and yellow pod, and then the offsprings can be observed.
if the offsprings are all phenotypically dominant then the green pod is homozygous and if there are phenotypically recessive offspring also present then the green pod is heterozygous genotypically.
Answer:
Planaria.
Explanation:
The kingdom eukarys is divided into the different phyla including almost all the animals. The organism are classified on the basis of their level organisation, cavity and on the basis of coelom.
The cephalization is initial process for the deposition of nervous tissue in brain. The cephalization is absent in porifera and coelenterate. The planaria also known as flat worms shows the process of cephalization and this process becomes more complex in higher animals.
Thus, the correct answer is option (4).
To separate the pebbles you should hand pick it,
meaning-from the word itself, you don’t have to use any kind of instrument but
your hand.
On the other hand, to separate the mud you can use
decantation or sedimentation or filtration.
To separate the husk you have to use sieving.
Carbon is one of the most common elements
Can form bonds and double bonds with up to 4 other atoms, including other carbon atoms
If you add more elements and you can create amino acids, and that is the base of all proteins.
