Passing of traits from parent to offspring

alternative forms of a gene

A sequence of DNA that codes for a protein and determines a trait.

The genetic makeup of a trait. For example: Tt or TT (T = tall height)

The physical characteristic of a trait. For example: A tall pea plant

A trait that was passed down from parents through DNA. Determined before birth.

A red flower is crossed with a white flower and results in pink flowers. What is this called?

This Punnett square shows a cross between ---

What percent of offspring will have be homozygous dominant?

What is one advantage of sexual reproduction?

At the end of Meiosis I :

At the end of Meiosis II :

The egg and the sperm are examples of

In humans, sperm cell have ___ chromosomes and are ___, while skin cells (somatic) have ___ chromosomes are are ___.

With mitosis you get ____________ cells, but with meiosis, you get _______________.

During Metaphase I in meiosis, all 46 homologous chromosomes line up in the middle of the cell, however the order in which they line up is random and leads to 8 million different combinations. This process is called _

In Dogs, they have 78 chromosomes in its body cells. How many chromosomes are in the gametes?

What is happening during crossing over in Meiosis?

In what phase of Meiosis 1 is crossing over occurring?

In which process are Gametes produced?

What is the purpose of meiosis?

Codominant and incompletely dominant traits have three phenotypes instead of two. How many alleles (versions of the gene) are involved?

In humans, curly hair is dominant to straight hair, and wavy hair is an intermediate texture. Which explanation most likely accounts for wavy hair?

In chickens, black is co dominant with white feathers. Which cross would result in 50% black and white feathers?

What are the genotypes for type A blood?

Which could NOT result from a cross between I^AI^B and I^Ai?

If your genotype is Bb, then you can only pass a B or b to your child but you can't pass both. Which law explains this idea?

A recessive allele is only expressed when a dominant allele is not present. What law matches this statement?

Different traits are inherited independently of each other and chromosomes will line up randomly during Metaphase I in meiosis. What law explains this statement?

Who is considered the "father" of modern genetics?

ABO blood type is controlled by three alleles. This is an example of what kind of inheritance?

Colorblindness is a sex-linked trait. Having normal vision (X^N) is dominant over colorblindness (Xⁿ). If a heterozygous mother has babies with a colorblind man, what are the chances that they will have a colorblind child?

Sex-linked traits occur on the ___ and are more likely to be expressed in ___.

Traits that are controlled by multiple genes and have many possible phenotypes are called

Objective #13

On a pedigree how do we know if they have the trait?

If this pedigree shows a recessive disorder, what MUST the genotype of individual 4 be?
