flower color of gumamela
human blood groups
Which of the following is TRUE about sex-linked traits?
Sex-linked traits are recessive.
They are controlled by the genes found in the somatic chromosomes
The traits are expressed only in one gender.
The traits are controlled by three or more alleles.
What pattern of inheritance is shown above?

100%
In some chickens, feather color is controlled by codominance. When a black chicken mates with a white chicken, all of the offspring are covered in both black and white feathers.
A farmer mates a black chicken (BB) with a black-and-white (BW) chicken.
What are the chances of having white chicken?
0%

In humans, hair texture exhibits incomplete dominance. The gene for curly hair (H) is incompletely dominant to the gene for straight hair (h). Individuals that are heterozygous (Hh) have wavy hair.

50%
25%
75%
0%
