Traits that Mendel studied.
What are seven "non-blending" pea plant traits.
100

The probability of two heterozygous tongue-rolling (Rr) parents having a child without the ability to roll his/her tongue, if being unable to roll one's tongue is a recessive trait?

What is 25%?

100

This allele that masks the effect of another allele for one gene.

What is the dominant allele?

100

Heterozygous defined

What is a hybrid or has one dominant allele and one recessive allele for one gene?

100

The number of chromosomes a gamete will have.

What is half the regular body cell? (half of what is in a somatic cell)

200
Reasons Mendel chose to study garden peas.
What is-they are easy to grow, have many offspring, and have distinct traits?
200

Letters represent this for the offspring inside the Punnett square.

What are genotypes (or alleles) of offspring?

200

The study of biology that involves how different traits are transmitted from one generation to the next.

What is genetics?

200

This cross that involves one trait where the parents are heterozygous for the trait.

What is a monohybrid cross?

200

Somatic cells are these

What are body cells?

300
Mendel referred to these as "factors" and are the genetic components of a trait
What is "alleles"?
300

Percentage of heterozygous offspring when 2 heterozygous parents are crossed for one trait.

What is 50%?

300

All the genes in an organism or a species.

What is a genome

300

Phenotype defined

What is the physical appearance of a trait?

300

The "ploidy" of all somatic cells

What is diploid?

400

Form Mendel, this was the "hidden trait" after crossing two different true breeders (like a true breeder for purple flowers with a true breeder with white flowers)

What is the recessive trait?

400

Genotype for pea plant that is heterozygous tall.

What is Tt?

400

This states that alleles of different genes (and different traits) separate during the process of meiosis to create unique gametes.

What is the Law of Independent Assortment?

400

Homozygous defined

What is an organism has two of the same alleles (2 dominant alleles or two recessive alleles) for a gene?

400

Different forms of a gene.

What are alleles?

500

This is the genotypic ratio seen with a monohybrid cross (Aa x Aa)

What is 1 AA : 2 Aa : 1 aa?

500

Capital letters show this in genetics.

What is the correct way to represent a dominant allele?

500
This states that the inheritance of one trait (and thus those alleles) has no effect on the inheritance of another trait (and thus those alleles).
What is the Law of Independent Assortment?
500

Phenotypic ratio for a monohybrid cross.

What is 3 (dominant) : 1 (recessive)?

500

These are examples of gametic cells.

What are sperm and egg cells?
