Mendelian Traits

You create a punnett square to determine the probability of hair color being passed to offspring. Brown hair is dominant. Blond hair is recessive. Both parents have brown hair. Both parents are heterozygous. What is the probability that the offspring will also have brown hair?

What is a genotype?

• The type of geno in the genes.

• The visible or physical trait resulting from the allele pair.

• The genetic combination of allele's in the allele pair.

• The width of the chromosome.

Dominant alleles are represented by a(n)

• upper case letter

• punnett square

from both parents for one trait
