Cattle egret follow herds of cattle and feed on both the insects stirred by the movement of the cattle and the biting insects th
kirill115 [55]

Commensalism relationship is shown between cattle egret and cattle.

Usually cattle egrets follow herds of large hoofed mammals such as cattle, buffalo. They eat the insects that have been stirred up by the buffalo as they move. This relationship is commensalism, because the birds benefit but the ungulate is neither harmed nor helped.

The cattle egret and grazing cattle in a close association is a classic example of commensalism. It is a common sight in rural areas where one can see ticks hovering over the cattle. They feed on cattle's blood and hence are harmful to them as they can transmit several diseases. The cattle egret and grazing cattle in a close association is a classic example of commensalism.

1. In a population of 200 field mice, 98 mice are homozygous dominant for brown fur (FF), 84 mice are heterozygous (Ff), and 18
iVinArrow [24]
A.
The genotype frequencies can be determined by dividing the number of individuals with a genotype by the total number all the individuals. 
FF genotype frequency:
98÷200=0,49. There are approximately 5 <span>homozygous dominant mice in 10.
Ff genotype frequency:
84</span>÷200=0,42. There are approximately 4 <span>heterozygous mice in 10.
ff genotype frequency:
18</span>÷200=0,09. There are approximately 1 <span>homozygous recessive mouse in 10.

B.
To determine the frequency of an allele we can divide the number of times that the allele appears by the total number of alleles.
F allele frequency:
</span>\frac{(98*2)+84}{400}<span>=0.7
There are 7 F alleles in 10 random alleles.
f </span>allele frequency:
\frac{84+(18*2)}{400}=0.3
There are 3 f alleles in 10 random alleles.<span>
