Q

F1 generation

Filial

A

First filial generation of offspring of distinctly different parents

17
Q

F2 generation

Filial

A

The filial generation comprised of offspring resulting from the mating of two members of fist filial generations

18
Q

Define linked genes

A

Genes on a chromosome are inherited together

19
Q

Define linkage groups

A

Packages of jeans that I always tended to be inherited together

20
Q

Define recombinant

A

Individuals with new combinations of jeans

21
Q

Define sex chromosomes

A

Seemingly mismatched chromosomes

22
Q

Define autosomes

A

Chromosomes that are the same between both male and female

23
Q

Define sex linked

A

A gene located on one of the sex chromosomes

24
Q

What are hybrids

A

Organisms produced by crossing parents with a different traits

25
Q

What is The first conclusion

A

Individual factors control the traits of organism

  • genes: control traits
  • alleles: contrasting forms of genes
26
Q

What is the second conclusion

A

Dominance principal

27
Q

Dominant allele

A

Always expressed and hides other (represented by capital letters)

28
Q

Recessive allele

A

Only expressed when a dominant gene is not present (represented by lower case letters)

29
Q

Define haploid

A

Cell with single set of unpaired chromosomes

30
Q

Define gamete

A

Mature haploid cell ready to fuse with another mature haploid cell

31
Q

Define zygotes

A

Diploid cell composed from the fusion of two haploid cells

32
Q

What is a cell with single set of unpaired chromosomes

A

Haploid

33
Q

What is a mature haploid cell ready to fuse with another mature haploid cell

A

Gamete

34
Q

What is a diploid cell composed from the fusion of two haploid cells

A

Zygotes

35
Q

What is the law of segregation

A

States that allele pairs separate or segregate during gamete formation and randomly unite at fertilization

36
Q

Genotype

A

The genetic constitution of an individual organism

37
Q

Phenotype

A

Characteristics of an individual resulting from the he interaction of its genotype with the environment

38
Q

What is independent assortment related to gamete formation

A

When the two factors for each trait are segregated during the formation of gametes
