Who is considered the Father of Genetics?
Gregor Mendel
the shape of Punnett squares
what are squares?
a trait that overpowers another trait or the recessive trait
what is a dominant trait?
The scientific name for a purebred in genetics
Homozygous
A purebred brown horse is crossed with a purebred cream horse. The offspring is a gold colored horse called a Palomino. In this case of incomplete dominance, write the genotype of the Palomino. Use Hb and Hc for alleles.
HbHc
the transmission, or passing of genes
what is heredity?
Two parents that are dominant homozygous for brown hair create an offspring, what is the child's hair color?
what is brown?
a trait is not observed, or is "hidden," in the phenotype of a heterozygous individual
what is a recessive trait?
The scientific name for a hybrid in genetics
Heterozygous

what is a trait?
purpose of a punnett square
used to determine the traits of an offspring
The trait that is normally the capital letter (B)
what is a dominant trait?
The physical expression of a trait is called
phenotype
a version of a gene
what is allele?
BB and a Bb cross, what is the percentage that the offspring has the dominant traits?
100%
The trait that is normally the lowercase letter (b)
what is a recessive trait?
The genetic combination of alleles for a trait is called
genotype
When an offspring born expresses both of its parents unique phenotypes separately, this is an example of which genetic occurrence?
co-dominance
bb and Bb cross, what is the percentage that the offspring has the dominant trait?
50%
Relating to genes or heredity of traits
what is genetics?
If an organism born shows a blend of its parents two different phenotypes, this is an example of which kind of genetic occurrence ?
Incomplete dominance
