Heredity in animals biology. made for students in grade 10

This is about human and animal genomes

1. Heredity

2. Vocabulary
Get the definitions for the following
terms from your text:
gene
genotype genome
phenotype allele
homozygous heterozygous
dominant recessive

3. Law of Segregation
•Organisms inherit two copies of each
gene, one from each parent
•Organisms donate only one copy of each
gene in their gametes
•Two copies of each gene segregate, or
separate, during gamete formation

4. Segregation and Inheritance

5. Traits Studied by Mendel

6. Flower Color
In pea plants:
The allele for violet flower color
(B) is dominant
The allele for white flower color
(b) is recessive

7. Genotype vs. Phenotype

13. Incomplete Dominance
In snapdragons red
flower color is due to
gene (R) and whiteto its
corresponding allele (r).
The heterozygous (Rr)
condition results in pink
flower color. This is
referred to as
“incomplete dominance.”
