A calico cat shows both the traits for orange fur and black fur. What kind of inheritance pattern is this?

Incomplete Dominance

Co Dominance

Sex-Linked

Polygenic

A red flowered plant (RR) breeds with a White flowered plant (WW). The gene for petal color in these plants expresses incomplete dominance. What percentage of the offspring will have pink (RW) flowers?

25%

50%

100%

This type of inheritance pattern is a Blend of both traits.

incomplete dominance

co-dominance

complete dominance

recessive pattern

Which of the following genotypes belongs in the red box in the Punnett square?

X^BX^B

X^bX^b

X^bY

X^BY

Hemophilia is a recessive x-linked disorder. According to the Punnett square, what percentage of offspring will have the disorder?

25%

50%

In chickens, black is co dominant with white feathers. Which cross would result in 50% black and white feathers?

BW x BW

BB x WW

BW x WW

WW x BB

A child has blood type AB. If blood types are passed on through codominance, which blood types would his parents most likely have?

B and O

O and A

A and B

AB and O

Some flowers are controlled by codominance. Red flowers (RR), blue flowers (BB) and Speckled flowers (RB).

Cross a red flower with a speckled flower. What is the phenotypic ratio?

2 red, 2 speckled

2 red, 2 blue

2 blue, 2 speckled

The sex of a child is determined by

whether the father's sperm contains an x or y chromosome

whether the mother's egg contains an x or y chromosome

the age of the parents

10.

Males are more likely to suffer from a sex-linked disease or disorder because

males are the weaker sex

males have less DNA

males have 1 X chromosome, so the disorder is more likely to be expressed

11.

When we say that a woman is a carrier for a genetic disease or disorder it means that

she has 1 gene, but not the disorder

she has 2 genes for the disorder

she can pass the gene only to male children

she can pass the gene only to female children

12.

Hemophilia is a recessive x-linked disorder.
Which genotype represents a female who is a carrier for hemophilia?

X^HX^h

X^hX^h

X^HX^H

X^hY

13.

A black male and white female produced this grey offspring:

Incomplete dominance

Codominance

Complete dominance

14.

A tall plant (TT) is crossed with a short plant (SS) and a medium plant (TS) results. This is what type of inheritance pattern?

Incomplete Dominance

Codominance

15.

How are Incomplete Dominance and Co Dominance different than a normal Mendelian cross?

There is no difference

The heterozygous genotype has a unique phenotype

There is no heterozygous genotype

There is only one phenotype regardless of genotype.
