Answer:

the sample of 200 medium ground finches measured in 1976 (Figure 1). The number of individuals has increased to close to the number of birds present in the population before the drought. However, the most common beak depth has increased from 8.8 mm to 9.8 mm .

Suppose the human trait for hair type is controlled by a simple dominant and recessive relationship at one locus. Curly hair, C,
Zepler [3.9K]

Answer:

The frequency of the dominant allele, C = 0.2234

and the heterozygous genotype, Cc= 0.1736

Explanation:

Given -  

Curly hair, C, is the dominant allele, and straight hair, c, is the recessive allele

Thus, C is dominant over c

The genotype frequency of curly hair is 52 in 131 students

so, remaining 131-52 = 79 are straight hair students.  

Since straight hair is a recessive allele , the genotypic frequency of "cc" is  

\frac{79}{131}\\0.6030

Frequency of "cc" is represented by q^{2}

Thus frequency of allele "q"  

= \sqrt{0.6030} \\= 0.7765

As per Hardy Weinberg's I equation -  

p+q=1\\p + 0.7765=1\\p = 0.2234

As per Hardy Weinberg's II equation -  

p^{2} +2pq + q^{2} =1\\0.2234^2+2pq+0.6030=1\\2pq= 0.1736

Hence,  

The frequency of the dominant allele, C = 0.2234

and the heterozygous genotype, Cc= 0.1736

Summarize variations in climate among three major zones as you travel south from the equator toward the South Pole?
Ainat [17]
Equator area: closest to the sun and hot and humid due to the mass evaporation from the excess heat. 

Mid equator/south pole: somewhat mild, colder, probably mid-humid, depending on which end of the midsection you're going for

South Pole: cold and dry. Cold because it's naturally far away from the sun (like the north pole) and dry because there isn't significant water evaporation here and any that may form crystallizes into snow and ice.
