GENETICS

Genetics 1

100

How many recessive alleles are needed for the trait to show up?

2

200

This is the PHYSICAL appearance of an organism.

Phenotype

300

How many parents are required for asexual reproduction?

ONE

400

This type of letter is used to represent a recessive gene.

Lower case letters

500

How do offspring compare genetically to their parent in asexual reproduction?

They are genetically identical

Genetics 2

100

What type of asexual reproduction involves a small version of the parent growing and detaching?

Budding

200

This is the different forms of characteristics.

Traits

300

Why can large populations from asexual reproduction be a disadvantage?

Creates food scarcity and competition

400

A hybrid brown-eyed man is crossed with a pure recessive blue-eyed woman. What percent of their offspring will have brown eyes?

50% will have brown eyes

500

How do plants reproduce through vegetative reproduction?

They grow new plants, using runners, bulbs, tubers, or plantlets.

Genetics 3

100

How many dominant alleles are needed for that trait to show up?

Only one

200

This is the allele combination or genetic makeup of an organism.

Genotype

300

What type of asexual reproduction occurs when an organism splits into two identical cells?

Fission or binary fission

400

This type of letter is used to represent a dominant gene.

Capital letters

500

Which method of asexual reproduction allows plants to spread rapidly through underground stems?

Rhizomes or runners (Vegetative Propogation)

Genetics 4

100

What is an example of an animal that reproduces by budding?

hydra

200

An organism that has a dominant and recessive allele for a trait.

Heterozygous or hybrid

300

How do environmental factors affect asexual reproduction? 

They create variation

400

2 hybrid brown-haired people are crossed. What percent of their offspring will have pure dominant traits?

25% will be pure dominant

500

What is an advantage of sexual reproduction?

Diversity or variation of traits

Genetics 5

100

An organism that has 2 different alleles for a trait.

Heterozygous or hybrid

200

A chart that shows all the possible combinations of alleles that can result from a genetic cross.

Punnett square

300

An organism that has 2 identical alleles for a trait.

Homozygous or purebred

400

A homozygous recessive white haired rabbit is crossed with a homozygous dominant brown haired rabbit. What genotype will all the offspring have? Use B/b for alleles.

All offspring will be "Bb".

500

2 heterozygous brown-eyed people are crossed. What are the possible genotypes and phenotypes of their offspring? Use B/b for alleles. (Brown eyes are dominant and Blue eyes are recessive)

Genotypes: 1 BB, 1 bb, 2 Bb Phenotypes: 3 brown eye, 1 blue eye
