If two loci R/r and W/w are linked and are 14 map units apart, and an RW/rw individual is testcrossed, you will obtain: Group of answer choices 1)7% RW individuals 2)86% Rw individuals 3)14% RW individuals 4)14% rW individuals 5)43% rw individuals

Within a large population, it is unusual for a single gene to have more than two different alleles (versions). A) True B) False

Below is the mapping data from three different crosses of Hfr strains with separate samples of an F- strain. Appearance of Genes in F- cells Hfrl: Genes d+ c+ ft et g+ Time (min) 4 15 26 44 58 Hfr2: Genes b+ d+ c+ f+ g+ 59 Time (min) 3 5 16 27 Hfr3: Genes et f+ c+ d+ b+ Time (min) 6 24 35 46 48 Use the mapping data from these interrupted conjugation crosses to construct a genetic map for these genes, indicating their order on the bacterial chromosome and the distances between them.

In assessing data that fell into two phenotypic classes, a geneticist observed values of 20:150. She decided to perform a Chi-Square (X) analysis by using the following two different null hypotheses: a) the data fit the 3:1 ratio, and b) the data fit the 1:1 ratio. Calculate the Chi-Square (x) values for each hypothesis. What can be concluded about each hypothesis?

In a certain population in the US, the frequency of CCR5-Δ32 homozygous individuals is 1%. Assuming genetic equilibrium, what is the frequency of heterozygotes in this population?

If one parent is dominant tall, and one parent is mixed hybrid, what is the phenotype in percentage (%) for the possible offspring? Use the reference sheet below to answer.

A population of dragons or Varanus dragonus has two alleles B and P encoding for phenotypes blue and purple scales, is dominant over B. You have population of 345 individuals. PP = 100, BP; =90 , and BB = 155 . What is the frequency of the P allele? Please use and round to four decimal points.

Could you please help find the type of trait and genetic interactions shown in this picture?

Snow geese (Chen caerulescens) come in two color types, white “snows” and “blues” with dark bodies. A single gene controls coloration, where the dark (“blue”) allele (D) is dominant. A population of 30,012 geese includes 9236 dark individuals. Genetic testing reveals that 7636 of the 9236 dark individuals are heterozygous (Dd). According to the Hardy-Weinberg equilibrium, what is the expected number of individuals of genotype Dd? Group of answer choices A.) 14752.40 B.) 13596.09 C.) 8898.56 D.) 3608.26
