Spider-Man and Spider-Woman are planning to have children in the near future. Spider-Man is able to spin webs (S) and cling to walls (C), whereas Spider-Woman can spin webs but cannot cling to walls. If both of these traits are inherited in a dominant manner (i.e., the dominant trait will always mask the recessive trait), Spider-Man is heterozygous for each trait, and Spider-Woman is heterozygous for the web-spinning trait...

1. B. Spiderman's genotype- SsCc.Explanation- He is heterozygous for both the traits i.e. he has two different alleles for each trait.
2. E. Spiderwoman's genotype- Sscc. Explanation- She is heterozygous for web spinning i.e. she has two different alleles for that trait and she is homozygous recessive for clinging to walls i.e. she can't cling to walls.
3. D. SC, Sc, sC, sc. Explanation- Gamete formation occurs by segregation of alleles and their independent assortment. A parent cell will produce 4 different types of gametes when the parental genotype is heterozygous for both the traits.
4. D. Sc and sc. Explanation- She is heterozygous for S trait and homozygous recessive for C trait. After segregation of alleles and independent assortment, these two different types of gametes are produced.
5. B. 12.5%. Explanation-
6. C. 25%. Explanation-
