Suppose there are two alleles for gene C: C1 and C2. C1C1, C1C2, and C2C2 are the three possible genotypes. The fitness for genotype C1C1 is represented by W11, C1C2 is represented by W12, and C2C2 is represented by W22. Match the correct change in fitness to each natural selection event.
1. Directional selection against recessive allele C2
2. Directional selection against dominant allele C1
3. Directional selection against incompletely dominant allele C1
4. Underdominance

Parthenogenesis is a type of reproduction that does not require a mate. it’s rarely seen in birds and higher vertebrates. parthenogenesis involves the formation of a zygote. but this zygote is formed without fertilization. in parthenogenesis, in the absence of a male gamete, the ovum develops directly in the zygote.
