Front (Question)

dominant gene

Back (Answer)

an allele that masks the effect of an another

Front (Question)

recessive gene

Back (Answer)

an allele that is masked by the alternative (dominant)

Front (Question)

gene

Back (Answer)

the factor that determines an inherited characteristic, located in chromosomes

Front (Question)

allele

Back (Answer)

an alternative form of a gene

Front (Question)

progeny

Back (Answer)

offspring

Front (Question)

principle of segregation

Back (Answer)

the principle that the alleles for a trait are separated during the formation of gametes

Front (Question)

monohybrid cross

Back (Answer)

a mating between individuals in which only one pair of contrasting alleles is being considered

Front (Question)

homozygous

Back (Answer)

a.k.a. pure-breeding individual has same alleles for particular characteristic

Front (Question)

heterozygous

Back (Answer)

a.k.a. hybrid individual has 2 different alleles for particular characteristic

#10

Front (Question)

phenotype

Back (Answer)

physical appearance of an individual determined by the expression of the alleles for that characteristic

#11

Front (Question)

genotype

Back (Answer)

the genetic make-up of an individual determined by the alleles for the characteristic being considered

#12

Front (Question)

first filial generation f1

Back (Answer)

offspring of the first set of parents

#13

Front (Question)

second filial generation f2

Back (Answer)

offspring from crossing the first filial generation

#14

Front (Question)

loci/locus

Back (Answer)

part of the chromosome where that gene is located

#15

Front (Question)

What did Gregor Mendel establish 2

Back (Answer)

• the various hereditary characteristics were controlled by factors (genes) that occurred in pairs • during the formation of the gametes, the pairs of each factors seperate and each gamete receives only one set of factors with the other set going to the other gamete not codominance or incomplete dominance!

#16

Front (Question)

Pedigree

Back (Answer)

a symbolic family tree showing males and females and those individuals that have a particular characteristic or disease

#17

Front (Question)

Autosomal

Back (Answer)

concerned with non-sex chromosomes

#18

Front (Question)

punnet square

Back (Answer)

predicts the probability of the genotype & phenotype of the offspring

#19

Front (Question)

codominance 2

Back (Answer)

two or more alleles are equally dominant both phenotypes are expressed e.g. I^A & I^a

#20

Front (Question)

multiple alleles

Back (Answer)

more than 2 alleles for a specific characteristic e.g. blood groups

#21

Front (Question)

genetic counselling

Back (Answer)

advice regarding the risks of genetic disorders in future children

#22

Front (Question)

Red-green colour blindness 2

Back (Answer)

• X-linked recessive • Lack the ability to discriminate between the colours green and red.

#23

Front (Question)

Haeomophilia 3

Back (Answer)

• X-linked recessive • The blood clots very slowly or not at all. • Prominent in the royal families that descended from Queen Victoria

#24

Front (Question)

Phenylketonuria 2

Back (Answer)

• Autosomal recessive • Can not produce the enzyme needed to break down phenylalanine which then accumulates, causing brain deformities and mental retardation.
