The genotype of the offsprings would be Cc, Cc, cc, cc i.e heterozygous cleft chin and no cleft chin. The phenotype of the offsprings could be 50% cleft chin and 50% without cleft chin.
there will be 50% chance of the child to have cleft chin.
Answer No 3:
A a
A Aa Aa
a Aa aa
There will be 25% chance for the offspring to have arched feet. As arched feet is a recessive trait, so for this trait to occur both the alleles of the gene should be recessive i.e aa.
Answer No 4:
B b
b Bb bb
b Bb bb
As blonde is a recessive trait, so both the alleles for this gene should be recessive for this trait to occur. Hence, according to the punnet square, there will be 50% chance for the offspring to be blonde.
Answer No 5:
F f
F FF Ff
f Ff ff
As normal vision is a resessive trait, hence both the alleles of the gene should be recessive for the trait to occur. According to the punnet square, there is 25% chance that the child will have normal vision.
<h2>Anterior-posterior orientation</h2>
Explanation:
Flatworms have an anterior-posterior orientation and as a result more coordinated and deliberate movement is established
- Flatworms also called Platyhelminthes are a phylum of relatively simple soft-bodied invertebrate animals
- They are the largest phylum of acoelomates and are found in marine,freshwater and even in some damp terrestrial environments
- Movement in some flatworms is controlled by longitudinal,circular and oblique layers of muscle
- Flatworms anterior end helps in moving towards their food while the posterior end ensures that these organisms walk away from irritants
Answer:
The Green plants are missing in the food chain
Explanation:
Producers: The green plants since they produce their own food are also termed as autotrophs. They absorb energy from the sun to make their food. In ocean the phytoplanktons are the producers. In oceans the zooplanktons eat the phytoplanktons. Again the smaller zooplanktons eaten by larger zooplanktons and this eaten by fish. The fish is eaten by a bird. The tertiary consumer.
Consumers: It includes all organism eat something to survive. They might be herbivores and carnivores
Decomposer: The microbes bacteria and fungi converts dead matter into carbon and nitrogen which backs into the atmosphere.
Answer:
Yellow
Explanation:
