4. A __________________ can help you predict what an offspring will look like.
a. ____________________ stands for dominant alleles.
b. ____________________ stands for recessive alleles.

5. Genotype—the _________________ of an organism
a. homozygous—an organism with two alleles for one trait that are _____________ (written T __ or t __)
b. heterozygous—an organism with two alleles for one trait that are ______________ (written T __)

6. Phenotype—the way an organism ____________________ as a result of its genotype

Answer 1

The different forms of a trait that a gene may have are alleles.
During meiosis, a pair of chromosomes separates and the sister chromatids move into separate sex cells.
Each sex cell now contains one allele for each trait.
The study of how traits are inherited is genetics.
B. Gregor Mendel—the father of genetics

Mendel was the first to use pea plants to explain heredity and to trace one trait for several generations.
Hybrid—receives two genetic information for a trait from each parent
a. Dominant allele—covers up or dominates the other trait
b. Recessive allele—the trait seems to disappear
Probability helps you predict the chance that something will happen.
A Punnett square can help you predict what an offspring will look like.
a. Uppercase letter stands for dominant alleles.
b. Lowercase letter stands for recessive alleles.
Genotype—the genetic makeup of an organism
a. Homozygous—an organism with two alleles for one trait that are identical (written Tt or tt)
b. Heterozygous—an organism with two alleles for one trait that are different (written TT)
Phenotype—the way an organism appears as a result of its genotype.

Answer 2

The different forms of a trait that a gene may have are alleles.

During meiosis, a pair of chromosomes separates and the chromatids move into separate sex cells.

Each sex cell now contains one allele for each trait.

The study of how traits are inherited is genetics.

B. Gregor Mendel—the father of genetics

Mendel was the first to use pea plants to explain heredity and to trace one trait for several generations.

Hybrid—receives different genetic information for a trait from each parent

a. Dominant allele—covers up or dominates the other trait

b. Recessive allele—the trait seems to disappear

Probability helps you predict the chance that something will happen.

A Punnett square can help you predict what an offspring will look like.

a. Capital letter stands for dominant alleles.

b. Lowercase letter stands for recessive alleles.

Genotype—the genetic makeup of an organism

a. Homozygous—an organism with two alleles for one trait that are the same (written T __ or t )

b. Heterozygous—an organism with two alleles for one trait that are different (written T)

Phenotype—the way an organism looks or behaves as a result of its genotype.
