FLASHCARD QUESTION

Front

What is co-dominance in genetics?

Back

Co-dominance is a type of inheritance pattern where both alleles in a heterozygous individual contribute to the phenotype, resulting in offspring that express both traits simultaneously.

2.

FLASHCARD QUESTION

Front

What is incomplete dominance?

Back

Incomplete dominance is a genetic situation in which one allele does not completely dominate another allele, resulting in a phenotype that is a blend of the two.

3.

FLASHCARD QUESTION

Front

What is the phenotypic ratio of a cross between a red flower (RR) and a white flower (WW) in incomplete dominance?

Back

100% of the offspring will have pink flowers (RW).

4.

FLASHCARD QUESTION

Front

In snapdragons, which genotype leads to a blended phenotype?

Back

The heterozygous genotype (RW) leads to a blended phenotype.

5.

FLASHCARD QUESTION

Front

What is the phenotypic ratio when crossing a red flower (RR) with a speckled flower (RB)?

Back

The phenotypic ratio is 2 red flowers to 2 speckled flowers.

6.

FLASHCARD QUESTION

Front

What does the term 'genotype' refer to?

Back

Genotype refers to the genetic constitution of an individual, specifically the alleles present for a particular gene.

7.

FLASHCARD QUESTION

Front

What is a Punnett square used for?

Back

A Punnett square is a diagram used to predict the outcome of a genetic cross by showing the possible combinations of alleles from the parents.
