This figure shows the results for _______ _______.

This figure shows the results for _______ _______.

Incomplete dominance

When a dominant allele does not fully mask the recessive allele:

Incomplete dominance

What is pedigree in a biological context?

Record of descent/ ancestry

Types of mutations that cause changes in structure (HINT: 4 types, separate with commas)

Deletion, duplication, translocation, inversion

Piece missing off the end of a chromosome:

Deletion

Chromosome piece appears twice:

Duplication

Piece is removed, then moves to wrong location.

Translocation

Piece comes back in wrong direction

Inversion

Which is missing from the list? Mendel worked with garden peas because they..

1. are easy to cultivate

2. are self-pollinating plants

3. have simple, objective traits

have a short generation

What is a result of non-disjunction?

Aneuploid cells

• 1 nuclear division

This overview best describes the process of...

Meiosis

Mitosis is a nuclear division process that allows _____ and ______ for cells.

Growth, repair

Meiosis is a nuclear division process to allow for ________ __________.

Sexual reproduction

When meiosis does not complete properly; causes genetic disorders

Non-disjuction

The microtubule organizing center (In animal cells only, come in pairs).

Centrosomes

Before mitosis begins, chromatin is wrapped and condensed into an 'X' shape... this is called a:

Chromosome

DNA & histone proteins are collectively called...

Chromatin
