In your notebook… think about your genetic family…

1. Are there some traits that your parents have but you don’t?

2. Are there some traits that you have but your parents don’t?

VOCAB FLIPDominant Recessive

Co-Dominant Alleles

Chromosomes Punnett Squares

•Observed trait of an organism that mask the recessive form of a trait.

•For example, the allele for widow's peak is dominant and the allele for straight hairline is recessive. One widow's peak allele (dominant) and one straight hairline allele (recessive), they will have a widow's peak.

DOMINANT

RECESSIVE: 

• Trait of an organism that can be masked by the dominant form of a trait.

• Traits due to recessive alleles are only observed when two recessive alleles are present.

CODOMINANCE:

•Codominance is a relationship between two versions of a gene. If two dominate, but different, genes are expressed, can sometimes create a blended phenotype (brown eyes + green eyes = hazel eyes)

ALLELE

• alternative forms of a gene for each variation of a trait of an organism.

CHROMOSOMES:

• are thread-like structures located inside the nucleus of animal and plant cells containing DNA. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA). Passed from parents to offspring, DNA contains the specific instructions that make each type of living creature unique.

PUNNET SQUARE

• The Punnett square is a diagram that is used to predict an outcome of a particular cross or breeding experiment.

• It is named after Reginald C. Punnett, who devised the approach. The diagram is used by biologists to determine the probability of an offspring having a particular genotype.
