Answer:
1 out of 16 or 1/16
Explanation:
Let:
R = Round seed r = wrinkled seed
Y = Yellow seed y = green seed
Starting from the parent generation or the P generation, the genotype of the parents would be:
RRYY x rryy
This is because the cross is between a parents that are "purebred" for specific traits. This means that the parents are homozygous for the traits which in genotype form is represented by either two capital letters or two lower case letters.
Attached is the F1 generation results between a cross between the P generation.
As you can see the genotype of all the offsprings is RrYy.
Now also below is the cross between the F1 generation offsprings.
For recessive traits, it is only expressed when the dominant gene is not in the genotype, or in other words, the genotype is all in small letters. Since we are looking at two traits, you need to look for how many squares out of the total have all lowercase letters.
There is only 1 rryy out of the 16 predictions. So the answer would be 1/16.
Answer:
Option C
Explanation:
Given ,
A1 allele is carried by 
% people
Let us assume A1 s dominant genotype
This means 
Thus, frequency of allele in the given population is 
It is also given that the population is in Hardy-Weinberg equilibrium thus
Frequency of fruit fly with genotype A2A2 will be
As per Hardy-Weinberg's second equation of equilibrium
Hence, option C is correct
A geographically large form of ecology is called a biome. Numerous approaches have been developed by ecologists to categorize the biosphere into major biomes.
<h3>What criteria are used to categorize biomes?</h3>
Based on the species that live there, a place is classified as a biome. Scientists can describe a biome by describing the temperature range, soil type, amount of light, and water that are particular to a location and provide niches for specific species.
<h3>What biome has warm summers and freezing winters? trees that progressively lose their leaves?</h3>
The prominent trees in this biome are called after them because they lose their leaves in the winter. These forests may have a 20 to 30 m tall overstory and a 5 to 10 m tall understory.

Allan already had a heart attack and can try to prevent another one by changing the diet, exercising, or even quit smoking, but there are non-modifiable risks such as age, sex and generic heritage, so If Allan is over 40 years old, male or comes from a family with heart diseases, Allan needs to be extra careful because those factors cannot be changed no matter how the way of life is changed.
