What Is The Probability That The Offspring Will Have Dimples?

Because dimples is an autosomal dominant trait, heterozygosity will express dimples, leading to a

50% chance

that the child will have dimples.

What is the probability percentage of offspring?

Divide the number of boxes with a dominant allele by four and multiply the result by

100

to get the percent chance that an offspring will have the dominant trait. For example (2/4)*100 = 50, so there is a 50 percent chance of an offspring having brown eyes.

How many of the children will likely not have dimples?

All eight children will have dimples, meaning

0

will NOT have them.

How do you calculate probability of offspring?

Count the total number

of boxes in your Punnett Square

. This gives you the total number of predicted offspring. Divide the (number of occurrences of the phenotype) by (the total number of offspring). Multiply the number from step 4 by 100 to get your percent.

What is the probability of the offspring showing the recessive trait?

If two heterozygotes are crossed, the probability that an offspring will show the dominant trait is 75% or 0.75. The probability that an offspring will show the recessive trait is

25% or 0.25

.

Do dimples come from Mom or Dad?

Facial dimples are genetically inherited. Since

his dad

also has dimples, it was pretty much a surefire outcome. Since dimples are a dominant trait, only one parent needs to have them. If you or your partner has dimples, there is an over 50% chance your baby will have them.

What is the rarest dimple?

Upper cheek dimples, known as “Indian Dimples” in Korean

, are some of the rarest dimples in the world. While only a small percentage of people in the world have these particular dimples, some idols are among the rare few!

What is the probability that parents AaBb and AaBb will have offspring with genotype AaBb?

The correct answer: The probability of an aabb offspring when AaBb x AaBb parents are crossed is

b. 1/16

.

What percentage of offspring is yellow?

The result is a

1 in 4 (25 percent)

probability of both parents contributing a Y, resulting in an offspring with a yellow phenotype; a 25 percent probability of parent A contributing a Y and parent B a y, resulting in offspring with a yellow phenotype; a 25 percent probability of parent A contributing a y and parent B …

Is PP genotype or phenotype?

A simple example to illustrate genotype as distinct from phenotype is the flower colour in pea plants (see Gregor Mendel). There are three available genotypes, PP (

homozygous dominant

), Pp (heterozygous), and pp (homozygous recessive).

How do we calculate probabilities?

1. Determine a single event with a single outcome.
2. Identify the total number of outcomes that can occur.
3. Divide the number of events by the number of possible outcomes.

What does sum mean in probability?

The sum and product rules of probability refer to methods of figuring out the probability of two events, given the probabilities of each event. The sum rule is for

finding the probability of either of two events that cannot occur simultaneously

.

What is the probability of YyRR?

From the cross worked out in the above Punnett square, we can see that the gametes from both parents combine to give rise to progeny with two characteristic genotypes, YyRR and yyRR. The chance for occurrence of each of these genotypes is

50%

.

What true plant always produces offspring with the same trait as the parents?

The result is highly inbred, or “true-breeding,”

pea plants

. These are plants that always produce offspring that look like the parent. Today, we know that these “true-breeding” plants are homozygous for most traits.

What is the percentage of a homozygous dominant offspring?

What does BB mean on a Punnett square?

BB is called

homozygous dominant

. Both genes are the same and dominant. The dominant trait is expressed. Bb is called heterozygous. The organism has a dominant gene and a recessive gene.
