Which term refers to an organism's physical appearance

Which term refers to an organism's genetic make up?

Which genotype represents a heterozygous individual?

Which genotype represents a homozygous dominant individual?

An allele whose trait always shows up in the organism when the allele is present.

Who is considered the "father" of genetics?

Another way to state (write) homozygous is

The study of heredity is known as

Which of Mendel's laws states that alleles are separated during meiosis?

Which of Mendel's laws states that alleles are distributed to gametes independent of one another?

When an area of a chromatid is exchanged with the matching area on a chromatid of its homologous chromosome, _________________ occurs

This allele will mask (cover up) the other allele

A genotype in which the two alleles of a gene are different

What predicted percentage of the offspring will be heterozygous?

What process is seen in the diagram?

If alleles look like AA in a genotype it is said to be

What shows the possible combinations of alleles that can result from a genetic cross?

How many times in meiosis does the cell divide?

The color purple (P) is dominant over the color white (p). According to the Punnett Square, what is the probability of an offspring being WHITE?

The color purple (P) is dominant over the color white (p). According to the Punnett Square, what is the probability of an offspring being PURPLE?

Which sex chromosome combination is for a female?

Are gametes (sex cells) haploid or diploid?

Meiosis makes sperm and egg cells. In humans, sperm and egg cells each have _____ chromosomes. Therefore a fertilized human egg cell (sperm and egg cell combined) would create a cell with a TOTAL of _____ chromosomes.

Type of cell division that reduces the number of chromosomes; therefore it is referred to as reduction division.

Complete the Dihybrid Cross, Box 1.

Let's say that the letter "A" is dominant for Allergies to pollen. This would mean that "a" is recessive. And the letter "B" is dominant for Brown eyes. This would mean that "b" is recessive.

Please complete the Genotype for Box 1.

Complete the Dihybrid Cross, Box 10.

Let's say that the letter "A" is dominant for Allergies to pollen. This would mean that "a" is recessive. And the letter "B" is dominant for Brown eyes. This would mean that "b" is recessive.

Please complete the Phenotype for Box 10.

What ratio of the offspring from the cross shown will be homozygous recessive for the  trait of tallness?
