Some angel Fish colors are determined by codominance. Possible phenotypes and genotypes of angel fish colors are shown.
Which table shows the expected phenotypes of offspring resulting from a cross between a black angelfish and a black-lace angelfish?
Albinism is an autosomal recessive condition. Which circle graph shows the genotype probability with an albino female mates with a male that is heterozygous for the albinism trait?
Normal fruit flies have brownish-yellow bodies, and this body color is dominant. A mutation in the gene for body color can produce flies with ebony body color. A homozygous normal fruit fly (e+e+) is crossed with a homozygous ebony fruit fly (EE). What is the predicted outcome of this genetic cross?
All the offspring will have ebony bodies.
of the offspring, 75% will have brownish-yellow bodies, and 25% will have ebony bodies.
All the offspring will have brownish-yellow bodies
Of the offspring, 75% will have ebony bodies, and 25% will have brownish-yellow bodies.
