Ch 11 Genetics Vocab

Front 1

mendel

Back 1

discovered what traits offsprings gets from there parents after doing a square chart

Front 2

heredity

Back 2

passing on of physical or mental characteristics genetically from one generation to another.

Front 3

alleles

Back 3

one of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome

Front 4

dominant trait

Back 4

if you go something similar to one family member then the other like your dad has green eyes and mom brown eyes and you get green eyes or if you look more like your mom then your dad

Front 5

recessive trait

Back 5

recessive traitsTraits that typically do not show in a person unless both genes for the trait are inherited

Front 6

phenotype

Back 6

phenotype the outward expression of the environmental effects on an organism's traits

Front 7

Genotype

Back 7

the genetic makeup of an organism

Front 8

homozygous

Back 8

having one each of two different alleles

Front 9

heterozygous

Back 9

both alleles are different, one is expressed and the other doesn't affect the organism and the allele that is expressed is dominant

Front 10

monohybrid

Back 10

using a single trait with two alleles

Front 11

dihybrid

Back 11

using two traits with two alleles each

Front 12

segregation

Back 12

the action or state of setting someone or something apart from other people or things or being set apart.

Front 13

ind assort

Back 13

random combinations of chromosomes in meiosis and of genes on different pairs of homologous chromosomes by the passage according to the laws of probability of one of each diploid pair of homologous chromosomes into each gamete independently of each other pair.

Front 14

gametes

Back 14

a mature haploid male or female germ cell that is able to unite with another of the opposite sex in sexual reproduction to form a zygote.

Front 15

zygote

Back 15

is a combination of the DNA in each gamete, and contains all of the genetic information necessary to form a new individual.

Front 16

incomplete dominance

Back 16

which one allele does not completely dominate another allele, and results in a new phenotype.

Front 17

cordominance

Back 17

a relationship between two versions of a gene. people receive one version of a gene called an allele from each parent.

Front 18

multiple alleles

Back 18

a series of three or more alternative gene only two of which can exist in any normal, diploid individual.

Front 19

polygenic

Back 19

is one whose phenotype is influenced by more than one gene
