Thank you We sneak and here's your shmoop du jour

00:05

brought to you by dominant genetic traits The bullies of

00:09

dna high school a three to one few notification E

00:14

o is seen in a large family when looking at

00:16

the inheritance of a widow's peak or a dominant trait

00:20

called w what is the likely gino type of the

00:24

parents of this family on here The pension Well gina

00:32

type determines fino type right That means the combination of

00:35

dominant and recessive genes determines how an organism looks well

00:38

Let's go through each possible genotype of mom and dad

00:41

to find out which one gives junior or junior et

00:43

a seventy five percent chance of having a widow's peak

00:46

This thing first up option a big big dubbed by

00:52

big big depth well that's both parents having two dominant

00:55

genes for this trait Well as you can see this

00:58

would lead to all big w's and afford a zero

01:01

fino typical ratio I one hundred percent of their kids

01:04

will have widow's peaks Unless of course they take matters

01:07

into their own hands Okay next up answer Be big

01:10

Big dubbed by little that little dub one parent has

01:13

two dominant genes The other has to recess it well

01:16

Different results on the last one but still a four

01:18

to zero fina typical ratio If there's even one big

01:22

w present in the fina type that means you're in

01:24

the widow's peak club Very exclusive All right let's try

01:28

See Big dead little dubbed by little little Nope This

01:32

gives their offspring a fifty fifty chance kind Of like

01:35

flipping a genetic coin yes okay last won The correct

01:39

answer is d big dud little dubbed by big doubled

01:41

up ah three to one ratio is the hallmark of

01:44

a mano hybrid One dominant one recess If cross if

01:48

both of your parents have a widow's peak and share

01:51

this type of genome there's a seventy five percent chance

01:54

or three to one that you or your brothers or

01:57

sisters have won so d it is want to learn

02:01

way more about widow's peaks Well good for you to

02:03

do a google search for widow's peak It's that simple
