Refers to one of the two forms of a gene. Ex. “T” or “t”
Allele
Genes
Locus
Hybrid
Recessive
If a cross is made with both homozygous parents, it is possible to determine that:
100% of the offspring will be heterozygous
25 % of the seeds will express the recessive trait.
75 % of the seeds will be rounded
50% of the offpring will be wrinkled seeds
What does it mean if an organism is heterozygous for a trait?
The allele combination of an organism (TT, tt, Tt)
The way an organism looks and behaves (tall or short)
An organism is heterozygous for a trait if its two alleles for the trait are different
An organism is homozygous for a trait if the two alleles for the trait are the same
What is the Law of Segregation?
An organism is homozygous for a trait if its two alleles for the trait are different
Genes for height can either produce genes for tall plants or genes for short plants
Every organism has two alleles of each gene and when gametes are produced the alleles separate
Genes for different traits are inherited independently of each other
An organism is a hybrid genotype (Tt) but is appears tall instead of short.
Law of Dominance
Law of Segregation
Law of Independent Assortment
Law states that 1 allele is more dominant than the other. Recessive allele is only expressed when dominant is not present
Law of dominance
Law of inheritance
Law which states that different traits are inherited independently of each other
Law of independent assortment
Genetics law
What does heterozygous mean?
An organism that has the same alleles for a trait (TT or tt)
An organism that has different alleles for a trait (Tt)
When neither allele is fully dominant; offspring is a mixture of both
the different forms of a trait (hair color--> brown, blonde, red
Which of the following genotypes is homozygous recessive?
Tt
tt
TT
T
Phenotype refers to the ______________________ of an individual.
genetic makeup
actual physical appearance
recessive alleles
