Q

physical characteristics

A

penotype

17
Q

genetic makeup

A

genotype

18
Q

genes that segregate independently( genes for seed shape and seed color in pea plants), do not influence each other’s inheritance

A

independent assortment

19
Q

one allele is not completely dominant over another

A

incomplete dominance

20
Q

both alleles contribute to the phenotype

A

co dominance

21
Q

white and red flowers

A

codominance

22
Q

pink flowers

A

incomplete dominance

23
Q

more than two alleles

A

multiple alleles

24
Q

traits controlled by two or more genes, having many genes

A

polygenic traits

25
Q

chromosomes that come from the male, has a corresponding chromosome from the female

A

homologous

26
Q

cell that contains both sets of homologous chromosomes, 2n=8, contain two complete sets of chromosome and genes

A

diploid

27
Q

single set of genes, n=4

A

haploid

28
Q

process of reduction division in which the number of chromosomes per cell is cut in half through separation of homologous chromosomes in a diploid cell (creates genetically different cells, 4 )

A

meiosis

29
Q

four chromosome structure, created during meiosis

A

tetrad

30
Q

eschange of alleles between homologous chromosomes

A

crossing over

31
Q

showing the relative locations of each known gene

A

Gene Map

32
Q

states that some alleles are dominant and others are recessive

A

principle of dominance

33
Q

MItosis results in the production of two genetically identical diploid cells, wheres Meiosis produces four genetically different haploid cells

A

difference between Mitosis and meiosis

34
Q

each chromosome is actually a group of linked genes, independent assortment still hold true, it is the chromosome, however, that assort independently, not individual genes

A

Gene Linkage explained

35
Q

two traits

A

dihybrids
