10. researchers observe a large population of birds on a remote island. birds in the population are found to have either red crest feathers or white crest feathers on their heads. genetic analysis indicates that the allele for red crest feathers is dominant over the allele for white crest feathers. in a survey of the population, the researchers determine the frequencies of the crest-feather phenotypes. the results of the survey are shown in the table below. phenotype frequencies in an isolated bird population phenotype number of individuals red crest feathers - 11,088 white crest feathers - 1,759 assuming that the bird population is in hardy-weinberg equilibrium, what proportion of future populations is expected to be heterozygous controlling crest feather color? give your answer as a value between 0 and 1, rounded to two decimal places.

Suppose that the proportion of the white crest alleles (r) is given by w and that of the Red crest allele (R) is given by p. We have that p+w=1. The probability that an individual has 2 r alleles is given by w*w since for each allele position the probability is w. Only these individuals have a White phenotype. Hence, we get that w^2= $\frac{1759}{1759+11088}$ ; the right hand side is the proportion of white birds in the total population. Doing the calculations, this yields that w=0.37. From this, we calculate that p=0.63. The possible ways we have heterozygous individuals are the combinations Rr and rR. The probability for each of those is p*w. Thus, the total probability is 2pw. This is equal to 0.466=0.47. This is the fraction of the future population that is going to be heterozygous assuming the conditions of the Handy-Weinberg equilibrium like random reproductive matching etc.

Suppose that the proportion of the white crest alleles (r) is given by w which of the Red crest allele (R) is given by p. We have that p+w=1.

The probability that a private has 2 r alleles is given by WW since for every allele position the probability is w. Only these individuals have a white phenotype.

What is probability?

Hence, we get that w^2= $\frac{1759}{1759+11088}$

The right-hand side is the proportion of white birds in the total population. Doing the calculations yields that w=0.37. From this, we calculate that p=0.63.

The possible ways we've heterozygous individuals are the combinations Rr and RR. The probability for every of these is PW. Thus, the total probability is 2pw.

This is equal to 0.466=0.47. This is the fraction of the future population that is going to be heterozygous assuming the conditions of the Handy-Weinberg equilibrium like random reproductive matching etc.

Thus, the result of the survey is 0.466=0.47.

the answer is admiramos

the rule for verbs is whoever you are referring to (in this case 'nosotros'), you need to change the ending of the word.

nosotros - amos

yo - o

tu - as

el, ella, usted - a

ellos, ellas, ustedes - an

(examples: nosotros bailamos (instead of bailar) or yo hablo (instead of habla)

Mouse liver cells were homogenized and the homogenate subjected to equilibrium density-gradient centrifugation with sucrose gradients. fractions obtained from these gradients were assayed for marker molecules (i. e., molecules that are limited to specific organelles). the results of these assays are shown in the figure. the marker molecules have the following functions: cytochrome oxidase is an enzyme involved in the process by which atp is formed in the complete aerobic degradation of glucose or fatty acids; ribosomal rna forms part of the protein-synthesizing ribosomes; catalase catalyzes decomposition of hydrogen peroxide; acid phosphatase hydrolysis monophosphoric esters at acid ph; cytidylyltransferase is involved in phospholipid biosynthesis; and amino acid permease aids in transport of amino acids across membranes. a) name the marker molecule and give the number of the fraction that is most enriched for each of the following cell components: lysosomes; peroxisomes; mitochondria; plasma membrane; rough endoplasmic reticulum; smooth endoplasmic reticulum.
