Question

part 2 procedure:the female monster (described in table 1) is married to a male monster (see table 2 below) and they plan to have baby monsters. they are interested in finding out the probabilities of which traits their offspring will have.1. fill in the missing genetic information in the table for the male.table 2: genotypes & phenotypes for male monster|trait|genotype|phenotype|| ---- | ---- | ---- ||eyes|ee|white||eye color (incomplete)|ee|white||skin color (codominant)|gg|green||tail shape|pp|straight||tail color|pp|purple||tail (regulatory gene)|tt|no tail||teeth|rr|round||feet (incomplete)|ff|blended toed||horn color|ww|white||ear shape|yy|round||ears (regulatory)|ee|have 2 ears||claws|ss|short|2. complete the punnett squares to predict what traits would result from a cross between the two monsters for each trait, and answer the following questions:a. eyes - what percent of offspring will have only one eye?b. eye color - what percent of offspring will have red eyes?c. skin color - what percent of offspring will have green skin?d. tail - what percent of offspring will have a tail?e. feet - what percent of offspring will have three toes?f. horn color - what percent of offspring will have purple horns?g. ears - what percent of offspring will have ears?h. claws - what percent of offspring will have long claws?

Explanation:

First, we need to infer the female monster's genotypes from the male's and the Punnett square for eyes (to complete all Punnett squares and verify the percentage questions):

Step1: Identify female eye genotype

From the eyes Punnett square: Male = $ee$, offspring all $Ee$ / $ee$. So female = $Ee$ (phenotype: one eye, since $E$ is dominant for one eye, $e$ is recessive for two eyes).

Step2: Eye Color (incomplete dominance)

Male = $ee$ (white). Assume female = $RR$ (red, incomplete dominance: $RR$=red, $Rr$=pink, $rr$=white). Punnett square:

$$\begin{array}{c|cc} & e & e \\ \hline R & Re & Re \\ R & Re & Re \\ \end{array}$$

All offspring $Re$ (pink), so 0% red.

Step3: Skin Color (codominant)

Male = $GG$ (green). Assume female = $GG$ (codominant, so $GG$=green, $Gg$=green-yellow, $gg$=yellow). Punnett square:

$$\begin{array}{c|cc} & G & G \\ \hline G & GG & GG \\ G & GG & GG \\ \end{array}$$

All $GG$, 100% green.

Step4: Tail Shape

Male = $PP$ (straight, $P$ dominant for straight, $p$ for curly). Assume female = $pp$. Punnett square:

$$\begin{array}{c|cc} & P & P \\ \hline p & Pp & Pp \\ p & Pp & Pp \\ \end{array}$$

All $Pp$ (straight), 0% curly.

Step5: Tail Color

Male = $Pp$ (purple, $P$ dominant for purple, $p$ for blue). Assume female = $pp$. Punnett square:

$$\begin{array}{c|cc} & P & p \\ \hline p & Pp & pp \\ p & Pp & pp \\ \end{array}$$

50% $Pp$ (purple), 50% $pp$ (blue).

Step6: Tail (regulatory gene)

Male = $tt$ (no tail, $T$ dominant for tail, $t$ recessive for no tail). Assume female = $Tt$. Punnett square:

$$\begin{array}{c|cc} & t & t \\ \hline T & Tt & Tt \\ t & tt & tt \\ \end{array}$$

50% $Tt$ (has tail), 50% $tt$ (no tail).

Step7: Teeth

Male = $RR$ (round, $R$ dominant for round, $r$ for sharp). Assume female = $rr$. Punnett square:

$$\begin{array}{c|cc} & R & R \\ \hline r & Rr & Rr \\ r & Rr & Rr \\ \end{array}$$

All $Rr$ (round), 0% sharp.

Step8: Feet (incomplete dominance)

Male = $FF$ (blended toes, $FF$=blended, $Ff$=three toes, $ff$=two toes). Assume female = $ff$. Punnett square:

$$\begin{array}{c|cc} & F & F \\ \hline f & Ff & Ff \\ f & Ff & Ff \\ \end{array}$$

All $Ff$ (three toes), 100% three toes.

Step9: Horn Color

Male = $ww$ (white, $W$ dominant for purple, $w$ for white). Assume female = $WW$. Punnett square:

$$\begin{array}{c|cc} & w & w \\ \hline W & Ww & Ww \\ W & Ww & Ww \\ \end{array}$$

All $Ww$ (purple), 100% purple.

Step10: Ear Shape

Male = $yy$ (round, $Y$ dominant for pointed, $y$ for round). Assume female = $YY$. Punnett square:

$$\begin{array}{c|cc} & y & y \\ \hline Y & Yy & Yy \\ Y & Yy & Yy \\ \end{array}$$

All $Yy$ (pointed), 0% round.

Step11: Ears (regulatory gene)

Male = $EE$ (has ears, $E$ dominant for ears, $e$ recessive for no ears). Assume female = $ee$. Punnett square:

$$\begin{array}{c|cc} & E & E \\ \hline e & Ee & Ee \\ e & Ee & Ee \\ \end{array}$$

All $Ee$ (has ears), 100% have ears.

Step12: Claws

Male = $SS$ (short, $S$ dominant for short, $s$ for long). Assume female = $ss$. Punnett square:

$$\begin{array}{c|cc} & S & S \\ \hline s & Ss & Ss \\ s & Ss & Ss \\ \end{array}$$

All $Ss$ (short), 0% long claws.
