1 answer:
Answer:
3 Pollen tube forms and grows through the style
5 Sperm fertilizes the egg
1 Pollen is released from the anther
4 The pollen tube reaches the ovule within the ovary
2 Pollen sticks to the stigma
Explanation:
The process of double fertilization entails the fertilization of the egg by one sperm and that of two polar nuclei to produce the triploid endosperm tissue that nourishes embryo.

Answer:
Frequency of allele S is p
Frequency of allele C is q
The population is not in Hardy-Weinberg equilibrium
Explanation:
Given -
Number of individuals with straight hair
Number of individuals with curly hair
Number of individuals with Wavy hair
Let "p" represents the frequency for allele for straight hair and "q" represents the frequency for allele for curly hair
represents the frequency of genotype "SS"
represents the frequency of genotype "CC"
represents the frequency of genotype "SC"
Frequency of allele S is p
Frequency of allele C is q
tex]= \sqrt{0.444} \\= 0.666[/tex]
For being in Hardy Weinberg's equation-
Substituting the values in above equation, we get -
hence, the population is not in Hardy-Weinberg equilibrium
