Mendelian Genetics Exam Study Guide
with Complete Solutions
alleles - ✔️✔️The different forms of a gene. Y and y are different alleles of the gene that
determines seed color. Alleles occupy the same locus, or position, on chromosomes.
autosome - ✔️✔️Any chromosome that is NOT a sex chromosome.
co-dominant alleles - ✔️✔️Two different alleles at a locus are responsible for different phenotypes,
and both alleles affect the phenotype of the heterozygote.
dominant trait - ✔️✔️A trait expressed in the phenotype if the dominant allele is present in the
genotype.
F1 generation - ✔️✔️Offspring of a cross between the parental (P1) generation.
F2 generation - ✔️✔️Offspring of a cross involving the F1 generation.
genotype - ✔️✔️The genetic constitution of an organims with respect to a trait. For a single trait
on an autosome, an individual can be homozygous for the dominant trait, heterozygous, or
homozygous for the recessive trait. Yellow seeds are dominant, but yellow seeded plants could
have a genotype of either YY or Yy.
heterozygous - ✔️✔️differing alleles for a trait in an individual such as Rr.
homologous chromosomes - ✔️✔️The pair of chromosomes in a diploid individual that have the
same overall genetic content. One member of each homologous pair of chromosomes inherited
from each parent.
homozygous - ✔️✔️Both alleles for a trait are the same in an individual. They can be homozygous
dominant (YY), or homozygous recessive (yy).
Incomplete dominance - ✔️✔️Intermediate phenotype in F1, parental phenotypes reappear in F2.
linkage - ✔️✔️Genes that are inherited together on the same chromosome.
Mendel's law of independent assortment of alleles - ✔️✔️Alleles of different genes are assorted
independently of one another during the formation of gametes.
