por Benjamin D Morgan

How many boxes would say BB?

Brown is dominant to green. What is the probability of these parents having green offspring?

1/4

2/4

3/4

4/4

The dominant trait is

yellow pea seeds

green pea seeds

there is no dominant seed

Jolly green giant

To be a yellow seed genotype must be

AA or Aa

A Punnet Square will

tell you exactly what your offspring will look like

increase the chance you pass on recessive traits

predict genotypes and phenotypes in offspring

have no purpose but for Taylor to give us extra assignments

How do two purple flowers produce white flower offspring?

They cant have white flowered offspring

Both flowers are heterozygous and can pass on the white allele

They are both homozygous Dominant

They do not have the recessive allele in their genotype

Both parents in this Punnet square

are homozygous dominant

are homozygous recessive

are heterozygous

have blue eyes

What allele combination should go in the missing box?

none of these

If B = brown hair and b = blonde hair, what is the probability of brown hair?

25%

50%

75%

T - tall and t = short In the punnett square below, what belongs in the missing square

Dominant alleles are represented by a:

male gene

lowercase letter

recessive trait

capital letter

BB, Bb, and bb are examples of _________________

Dominant

Homozygous

Genotype

Phenotype

This is the expression of alleles. It is the observable trait we can see _________________

Dominant

Homozygous

Genotype

Phenotype

In some animals, brown eyes (B) are dominant over blue eyes (b). Which of these genotypes will complete the Punnett Square to the right?

What would go into punnet square 1

all choices

What would go into punnet square 2

all choices

What would go into punnet square 3

all choices

What would go into punnet square 4

all choices

What would go into punnet square 1

What would go into punnet square 3

What would go into punnet square 2

If two organisms reproduce sexually, then their offspring will exhibit a genetic makeup that is -

identical to only one parent

identical to all of its siblings

a unique combination of traits

the recessive traits of each parent

How many parents does asexual reproduction involve?

one

two

three

four

The offspring from asexually reproduced organisms are?

Different than their parents

Identical to parents

Like a combination from both parents

A different species

utations are a source of _______________.

Variation

Disease

Polypeptide

Any change in the sequence of DNA is...

Transgenic Shift

Single Genotype

Monohybrid Trait

Mutation

Are all mutations bad?

yes

Mutations:

are permanent changes in the DNA sequence or structure

produce allelic variation

are more likely to neither harm or help the organism

all of the above

Which of the following is heterozygous?

Which of the following is homozygous recessive?

Which of the following is homozygous dominant?

Mark is heterozygous. If B is for brown hair, and b is for blonde hair, what is Mark's phenotype?

Brown Hair

Blonde Hair

Brown and Blonde Hair

Black Hair

Mark is heterozygous. If B is for brown hair, and b is for blonde hair, what is Mark's genotype?

Genetic variation describes offspring that have different traits, such as Paulie and Nicole. Offspring with different traits must be a result of

asexual reproduction

sexual reproduction

Why do Paulie and Nicole have so many different traits?

Paulie got more DNA from their mom, while Nicole got more DNA from their dad

Paulie and Nicole both got half their DNA from mom and half from dad, but they get different genetic combinations

Paulie and Nicole are not actually related

Paulie's DNA has a lot of mutations, which are very common

What is another reason for genetic variation besides sexual reproduction?

Partial mating

Asexual reproduction

Unequal chromosome distribution

Mutation

Sara has red hair. No one else in her family has red hair except her grandmother. How is this possible?

Red hair is random and cont connected to past generations

The genetic information for red hair was destroyed in the rest of Sara's family

Sara shares DNA with Grandma, but not her own parents

Grandma passed down some genetic information from her DNA to Sara

A pure plant that has a genotype of GG is crossed with a pure plant that has the genotype gg. What are all the possible genotypes of the offspring?

GG, gg, and Gg

only Gg

only GG

GG and gg

The differences in the sets of alleles between individuals in a population

genetic variation

gene

allele

none of the above

An organism's appearance or other detectable characteristic

genotype

phenotype

allele

genetic variation

Genetic variation allows for...

Species to change over time

Populations to survive

Differences in a population

All choices

What causes genetic variation? (pick all correct choices)

Choose one or more answers

Mutations

Sexual Reproduction

Asexual Reproduction

Mitosis

cell division

A mutation occurs at the genetic level. What does this cause?

The gene (allele) makes a different protein

The gene (allele) codes for a different trait
