FLASHCARD QUESTION

Front

What is codominance?

Back

Codominance is a genetic scenario where both alleles in a heterozygous individual are fully expressed, resulting in offspring with a phenotype that is neither dominant nor recessive.

2.

FLASHCARD QUESTION

Front

What is incomplete dominance?

Back

Incomplete dominance is a genetic situation where one allele is not completely dominant over the other, leading to a blending of traits in the phenotype of the offspring.

3.

FLASHCARD QUESTION

Front

In a Punnett square, what does a 50% chance of a trait indicate?

Back

A 50% chance indicates that there is an equal likelihood of the offspring expressing either of the two traits being considered.

FLASHCARD QUESTION

Front

What phenotype results from a cross between a homozygous black cat (BB) and a homozygous white cat (WW) under incomplete dominance?

Back

The phenotype of the offspring will be gray (BW), showing a blend of both traits.

5.

FLASHCARD QUESTION

Front

What is the expected phenotype ratio in a monohybrid cross involving codominance?

Back

The expected phenotype ratio is 1:2:1, representing the three possible phenotypes.

6.

FLASHCARD QUESTION

Front

If a plant with red flowers (RR) is crossed with a plant with white flowers (WW) and the offspring are all pink (RW), what type of inheritance is this?

Back

This is an example of incomplete dominance.

FLASHCARD QUESTION

What is the phenotype of a calico cat?

Back

A calico cat exhibits both orange and black fur, demonstrating codominance.
