Violence

Violence is defined as a physical act that causes or is intended to cause harm. Violence can cause physical, emotional, or both types of harm. Violence is defined by the World Health Organization as the intended use of physical force and power that causes threat or harm against oneself, another person, or against a community or group, and has the potential to cause damage, death, mental distress, maldevelopment, or poverty.

Question

I need help with question #13 part B . please help

13. Petal coloration of pea plants has a complete dominance relationship where purple petals are dominant
over white petals. There are 276 plants, 273 have purple petals.
a. Find: the frequency of the dominant and recessive alleles and the frequency of individuals with the
dominant, heterozygous, and recessive genotype.
b. After 100 generations, the population of pea plants grows to 620. If the plant population is in hardy
Weinberg equilibrium, how many pea plants would have white and purple flowers?
14. A student in a dorm discovers a room full of 666 cockroaches which included 24 albinos. These albinos
were so scary looking that the student squashed them and let the remaining cockroaches breed. The next
generation of cute little baby cockroaches totaled 13,485. Assuming that the allele for albinism is recessive
how many of these youngsters were albino?
Frequency of albino cockroaches = q^2= 24/666 0.036
Number of albino individuals in youngsters 0.036 * 13, 485 = 486
