Flashcards in Heredity Deck (16):
1

The passing of genetic traits from parent to offspring.

Heredity

2

The trait observed in the first generation when parents that have different traits are bred.

Dominate Traits

3

A trait that reappears in the second generation after disappearing in the first generation when parents with different traits are bred.

Recessive Trait

4

One set of instructions for an inherited trait.

Gene

5

One of the alternative forms of a gene that governs a characteristic , such as hair color.

Allele

6

An organism's appearance or other detectable characteristics.

Phenotype

7

The entire genetic makeup of an organism.

Genotype

8

The likelihood that a possible future event will occur in any given instance of the event.

Probability

9

Chromosomes that have the same sequence of genes and the same structure.

Homologous Chromosomes

10

A process in cell division during which the number of chromosomes decrease to half the original by two division of the nucleus which results in the production of sex cells.

Melosis

11

One of the pair of chromosomes that determine the sex of an individual.

Sex Chromosomes

12

A diagram that shows the occurrence of a genetic trait in several generations of a family.

Pedigree

13

A molecule that is present in all living cells and that contains the information that determines the traits that a living thing inherits and needs to live.

DNA

14

In a nucleic-acid chain, a sub unit that consists of a sugar, a phosphate, and a nitrogenous base.

Nucleotide

15

A molecule that is present in all living cells and that plays a role in protein and protection.

RNA

16

A change in the nucleotide-base sequence of a gene or DNA molecule.
