Answers to Genetics Practice worksheet

Homozygous for each trait:

Dark eyes= DD

Short legs= ll

Wide stripes= WW

Simple tail= tt


Heterozygous

Long legs= Ll

Brown fur= Bb

Wide stripes= Ww

Complex Tail= Tt


Phenotypes

DdTt= dark eyes, complex tail

Llbb= Long legs, white fur

ddbb= white eyes, white fur


Parents: Bb x Bb

Genotypic Ratio: 1 RR: 2Rr: 1 rr

Phenotypic Ratio: 3 brown fur: 1 white fur

White brown


Vocab answers
Vocab Answers

  • The combination of alleles: Genotype

  • A characteristic of an organism: Trait

  • Two alleles are the same: Homozygous

  • Two alleles are different: Heterozygous

  • Only one of this allele needed to see trait: Dominant

  • Part of a chromosome that determines a trait: Gene

  • Two of this allele needed to see trait: Recessive

  • A form of a gene: Allele

  • The observed trait of an organism: Phenotype


- What is the TRAIT for the animals? noseshape

- What is the genotype of animal 1?

NN

- What is the recessive form of the trait? Horizontal nose shape

- What is the phenotype for animal 3? Horizontal nose
