n 2 of 16 IncorrectIncorrect Incorrect Sapling Learning Map Suppose there are four newly discovered genes, each with two alleles, in humans that all follow a simple Mendelian inheritance pattern. Alleles are noted by a + or for dominant and recessive, respectively. The genes and their phenotypes are listed in the table below. Gene Wiz Serp Time Drgn Have the ability to cast spells Can communicate with snakes Have the ability to travel through time Have the ability to hatch dormant dragon eggs Cannot hatch dragon eggs Dominant Phenotype Cannot cast spells Cannot talk to snakes Experience normal time What is the probability of two completely heterozygous parents having a child with a Wiz Wiz erp'Serp genotype or a child with a Wiz Wiz Serp Serp genotype? Enter your answer as a Incorrect Each of the two genotypes are mutally exclusive of one another. First, calculate the probability of two heterozygous parents having a child with the first Wiz and Serp genotypes by multiplying the probabilities of obtaining the genotypes from each of the two loci. Next, calculate the probability of having a child with the second Wiz and Serp genotypes using the same strategy, Finally, add these two probabilities together Number 0.063 1.

Explanation / Answer

Wiz+ = W

Wiz- = w

Serp+ = S

Serp- = s

Parental cross: WwSs X WwSs

Progeny:

Phenotypic ratio:

W_S_ = 9/16

W_ss = 3/16

wwS_ = 3/16

wwss = 1/16

Genotypic ratio:

WWSS = 1/16

WWSs = 2/16

WwSS = 2/16

WWss = 1/16

WwSs = 4/16

Wwss = 2/16

wwSs = 2/16

wwSS = 1/16

wwss = 1/16

Required progeny = Wiz+ Wiz- Serp+ Serp+ = WwSS = 2/16 = 1/8 = 0.125

Required progeny = Wiz+ Wiz+ Serp- Serp- = WwSS = 1/16 = 0.0625
