1. Deafness is caused due to rupturing of pinna.
2. Watson and Crick showed the double helical structure of the molecule RNA.
3. Remarkable human fossil was that of Homo habilis.
4. Apical dominance is caused by auxins.
5. Cones enable us to see in darkness
6. Everyone in Squidward's family has light blue skin, which is the dominant trait for body color in his hometown of Squid Valley. His family brags that they are a "purebred" line. He recently married a nice girl who has light green skin, which is a recessive trait. Create a Punnett square to show the possibilities that would result if Squidward and his new bride had children. Use B to represent the dominant gene and b to represent the recessive gene.
A. List the possible genotypes and phenotypes for their children.
B. What are the chances of a child with light blue skin?_______%
C. What are the chances of a child with light green skin?_______ %
D. Would Squidward's children still be considered purebreds? Explain!

4.Name a pair of chromosome carrying alleles for a particular character.
5.V-shaped chromosomes having centromere at centre.
6.Stage after crossing over occurs in meiosis.
