Answer:
The proportion of a genotype (i.e., AB) in a population.
Explanation:
- Every trait is controlled by some alleles and their combinations. Allele frequency determines the frequency of occurrence of a particular allele in a population.
- It can be determined by genotype frequency or proportion of a particular genotype in a population. As a genotype is a result of various alleles coming together, its frequency can help us to calculate the allele frequency.
- For example, in a population with two alleles A and B, A allele can either occur as AA or as AB. To calculate the frequency of A we will have to calculate the genotype frequencies of AA and AB.
Gymnosperm plants important adaptation of the seed allowed plants to spread quickly across the land.
What is a gymnosperm ?
- Unlike angiosperms, or flowering plants, whose seeds are enclosed by fully developed ovaries, or fruits, gymnosperms, or any vascular plant, reproduce by the use of an exposed seed, or ovule.
- Many gymnosperms bear their seeds in cones, which are known as "raw seeds" because they are not visible until they are fully developed.
- Yew ,Gingko biloba, Cycads , Pines, Spruce are examples of gymnosperm
What is adaption in plants?
- Special characteristics that enable a plant or animal to survive in a specific location or habitat are known as adaptations.
- The plant can find it exceedingly challenging to live in a foreign environment because of these adaptations.
- This explains why some plants are only found in particular places.

Answer:
The bugs evolved beak lengths that were adapted to their host plant.
Explanation:
This is an interesting case of evolution in which bugs evolved (changed) quickly over a few generations. In less than 50 years the bugs evolved beak lengths to match the size of the new host plant’s seed pods. The bugs were not used to live out of that plant but they started feeding on it and then they changed some of their characteristics.
