Dominant - the allele that expresses itself at the expense of an alternate allele; the phenotype that is expressed in the F1 generation from the cross of two pure lines
Recessive - an allele whose expression is suppressed in the presence of a dominant allele; the phenotype that disappears in the F1 generation from the cross of two pure lines and reappears in the F2 generation
Mendel’s Conclusions
The hereditary determinants are of a particulate nature. These determinants are called genes.
Each parent has a gene pair in each cell for each trait studied. The F1 from a cross of two pure lines contains one allele for the dominant phenotype and one for the recessive phenotype. These two alleles comprise the gene pair.
One member of the gene pair segregates into a gamete, thus each gamete only carries one member of the gene pair.
Gametes unite at random and irrespective of the other gene pairs involved.
Mendelian Genetics Definitions
Allele - one alternative form of a given allelic pair; tall and dwarf are the alleles for the height of a pea plant; more than two alleles can exist for any specific gene, but only two of them will be found within any individual
Allelic pair - the combination of two alleles which comprise the gene pair
Homozygote - an individual which contains only one allele at the allelic pair; for example DD is homozygous dominant and dd is homozygous recessive; pure lines are homozygous for the gene of interest
Heterozygote - an individual which contains one of each member of the gene pair; for example the Dd heterozygote
Genotype - the specific allelic combination for a certain gene or set of genes
Problems:
A sexually reproducing animal has two unlinked genes, one for head shape (H) and one for tail length (T). Its genotype is HhTt. Which of the following genotypes is possible in a gamete from this organism?
A) T
B) HT
C) Hh
D) HhTt
A man has extra digits (six fingers on each hand and six toes on each foot). His wife and their daughter have the normal number of digits (five fingers on each hand and five toes on each foot.) Having extra digits is a dominant trait. The couple’s second child has extra digits. What is the probability that their next (third) child will have extra digits?
A) 1/2
B) 1/16
C) 1/8
D) 3/4
