What is the percentage of homozygous recessive offspring?

25%

50%

75%

this image is an example of

codominance

dominance

incomplete dominance

12.

A breed of chicken shows codominance for feather color. One allele codes for black feathers, another codes for white feathers. The feathers of heterozygous chickens of this breed will be:

all black

all white

all gray

speckled black and white

13.

In some carnations, flower color exhibits codominance. Identify the correct genotypes for red, white, and speckled carnations.

Red = RR, white = rr, speckled = SS

Red = RR, white = WW, speckled = SS

Red = RR, white = RW, Speckled = WW

Red = RR, white = WW, speckled = RW

14.

If this image were real, it would represent what type of inheritance?

incomplete dominance

codominance

polygenic inheritance

compete dominance

15.

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%

16.

The different forms of a gene are called

traits

pollinators

alleles

hybrids

17.

A roan cow shows codominance in fur color (brown and white). What is the phenotype ratio expected in offspring a female roan and a male roan mate together?

All four would be brown and White

Half would be orange, half would be white

2 Brown: 2 Brown and White: 0 White

1 Brown: 2 Brown and White: 1 White
