Genetics Review

Study of the way traits are passed on from parent to offspring

In flowers, red (R) is dominant to yellow (r). If two flowers that are heterozygous are crossed, what would be their potential genotypes of their offspring?

Characteristics of our genes

A trait that is covered up or seems to disappear

In flowers, red (R) is dominant over yellow (r) . What would be the potential phenotypes of potential offspring if parent 1’s genotype is RR and parent 2’s is rr?

Male or female sex cells

Two flowers are crossed and their resulting offspring genotypes are 50% RR and 50% Rr. What are the parent genotypes?

Is a trait that is always expressed, or shown

Is the following genotype homozygous or heterozygous: Tt

In dogs, brown fur (B) is dominant to black fur (b). What must be the parent genotypes of a puppy with black fur?

The study of how traits are inherited in offspring

Basic unit of genetic information, determine the inherited characteristics

The outside appearance of an organism

Pairs of genes that carry the same traits and are found at the same locations on pairs of chromosomes

In humans, brown eyes (B) is dominant to blue eyes (b). If two parents have brown eyes, but are carriers for the blue eye allele, what is the probability they will have offspring with blue eyes?

An offspring that has many generations of the same trait

The genetic makeup of an organism

Both genes for that trait are not the same

Used to calculate the frequencies of different genotypes and phenotypes among offspring

In humans, being a tongue roller (R) is dominant over non-roller (r). A man who is a non-roller marries a woman who is heterozygous for tongue rolling. What are the chances for an offspring with the genotype Rr?

Both genes for that trait are the same

Would the genotype AA be considered heterozygous or homozygous?
