Punnet Squares + Intro to Averages

Multiple Choice

Heterozygous is when...

• the alleles are the same

• the alleles are different

• the alleles are absent

• the alleles are present

Multiple Choice

This type of allele masks the recessive allele and is capital ________________

• Dominant

• Homozygous

• Genotype

• Phenotype

Multiple Choice

What is a phenotype

• The genetic make up (code)

• The physical trait

Multiple Choice

What are different forms of a gene called?

• Alleles

• Chromosomes

• Factors

• Traits

Creating and Solving monohybrid Punnett squares

Please watch the directions twice and take notes- Questions to follow

Multiple Choice

• AA

• Aa

• aa

• none of these

Multiple Choice

• tt

• Tt

• Bb

• TT

Multiple Choice

Genotype and phenotype ratio and percentages

In four squares, each square represents 25% of the total or 1/4.

Multiple Choice

What are the chances that the offspring will have homozygous recessive traits?

• 1 in 4

• 3 out of 4

• 75%

• 50%

Multiple Choice

The dominant trait is

• yellow pea seeds

• green pea seeds

• there is no dominant seed

• Jolly green giant

Multiple Choice

The genotypic ratio here is

• 25% blue eye 75 % brown eye 

• BB = 25% Bb = 50% bb = 25%

• BB= 50 % bb = 50%

• All brown eye

Multiple Choice

What is the genotypic ratio represented by the punnett square?

• 1:1

• 3:1

• 1:3

• 1:2:1

• Mean- average.

Median

Example

Multiple Choice

Find the median of these numbers:
4,2,7,4,3

• 2

• 5

• 7

• 4

Multiple Choice

What is the median?

mean

should be able to do it by hand, but calculator will come in handy. know how to do it by hand.

Multiple Choice

Find the mean of these numbers:
2, 57, 38, 42, 6

• 29

• 38

• 50

• 145

Multiple Choice

Find the mean of the numbers below:

12, 8, 14, 5, 1, 3, 0, 8, 10, 11

• 7.2

• 8

• 9

• 7.4

Mode

The easiet one. Mode means the most. Which numbers appears the most. isnt that hard. please dont mess this up.

Multiple Choice

At Donald's Donuts the number of donut holes in a bag can vary. Help Donald find the mode.
12,10,10,10,13,12,11,13,10

• 13

• 12

• 11

• 10

Multiple Choice

The scores awarded to 25 students for an assignment were as follows:

4 7 5 9 8 6 7 7 8 5 6 9 8 5 8 7 4 7 3 6 8 9 7 6 9

What is the mode?

• 6

• 7

• 8

• 9

Frequency table

this is a frequency table. it tells you how many of each value there are. so it shoul d be pretty easy to find a few things.

Mode number of pets?

Median number of pets?

Total number of pets?

Mean number of pets per student?

Multiple Choice

What is the definition of the mean?

• The average

• The middle number

• The difference between the highest and lowest numbers

• The number that occurs the most
