How many alleles for a trait will you pass on to your child?

1

At minimum, how many dominant alleles do you need to show the dominant trait

1

The second generation of offspring, obtained from an experimental cross of two organisms; the offspring of the F1 generation

f2 generation

The first generation of offspring obtained from an experimental cross of two organisms

f1 generation

This process makes identical body cells to allow organisms to grow and repair tissue. Also used for Asexual reproduction.

Mitosis

Who is considered the father of modern genetics?

Gregor Mendel

_____ plants are a good choice to use by Mendel because they are fast growing and easy to raise.

Pea

The study of how traits are inherited in offspring

Genetics

Two flowers are crossed and their resulting offspring genotypes are 50% RR and 50% Rr. What are the parent genotypes?

RR and Rr

In flowers, red (R) is dominant to yellow (r). If two flowers that are heterozygous are crossed, what would be their potential genotypes of their offspring?

25% RR 50% Rr 25% rr

In dogs, brown fur (B) is dominant to black fur (b). What must be the parent genotypes of a puppy with black fur?

bb and bb

In humans, brown eyes (B) is dominant to blue eyes (b). If two parents have brown eyes, but are carriers for the blue eye allele, what is the probability they will have offspring with blue eyes?

25%

In humans, being a tongue roller (R) is dominant over non-roller (r). A man who is a non-roller marries a woman who is heterozygous for tongue rolling. What are the chances for an offspring with the genotype Rr?

50%

In flowers, red (R) is dominant over yellow (r) . What would be the potential phenotypes of potential offspring if parent 1’s genotype is RR and parent 2’s is rr?

100% red

An allele whose trait always shows up in the organisms when the allele is present

dominant allele

An allele that is masked when a dominant allele is present

recessive allele

Having two identical alleles for a trait

homozygous

Having two different alleles for a trait

heterozygous

The genetic makeup of an organism

genotype

Cell division where the chromosomes in a cell nucleus are separated into two identical sets of chromosomes, each in its own nucleus.

mitosis

Cell division that halves the number of chromosomes when forming sex cells

meiosis

XX is what gender?

female

Aa x Aa

25% AA, 50% Aa, 25% aa

AA x Aa

50% AA, 50% Aa, 0% aa

aa x AA

0% AA, 100% Aa, 0% aa

A chart that shows all possible combinations of alleles.

punnett square

A sex cell formed in the male reproductive organs that contains half the number of chromosomes as body cells

sperm

sex A cell formed in the female reproductive organs that contains half the number of chromosomes as body cells.

egg cell

Where is genetic material located in a plant or animal cell?

Nucleus

What is an example of genetic material?

DNA, genes, or chromosomes

How many chromosomes do humans have?

46 or 23 pairs

True or False: Chromosomes contain genes

True

What is a section of DNA called?

Gene

What is the passing down of traits from one generation to next generation?

Heredity

What is a characteristic or feature determined by genes?

Inherited Trait

How many chromosomes do human sperm and egg cells (gametes) have?

23

Which trait will always express itself regardless of what other trait it is paired with?

Dominant

What is the structure made of tightly coiled DNA?

Chromosome

True or False: In his genetics experiments with pea plants, Gregor Mendel determined traits were passed down in a random pattern.

False: It is in a predictable pattern

What are the different forms of a gene called?

Alleles

What is the observable characteristics in an individual resulting from the expression of genes?

phenotype

What are the chances of a woman with Type AB and a man with Type A having a child with Type O?
