If Emily is pure dominant, what is her genotype?
Identify the genotypes of the parents in the boxes provided.
A genetic cross involving one gene is represented below.
Which genotype is NOT possible in the offspring produced by the cross?
Possible genotypes and phenotypes of angelfish are shown below.
Which table shows the expected phenotypes of offspring resulting from a silver angelfish and a heterozygous black angelfish?
In cattle the allele for cloven hooves (H) is dominant over the allele for mule-foot hooves (h). The phenotypes for each trait are shown below in the picture.
The probability (% chance) that the offspring will have cloven hooves if both parents are heterozygous is
In tomato plants, hairless stems are present in tomato plants that are homozygous recessive for that trait. Plants that have the dominant trait have hairy stems.
If a homozygous recessive plant mates with a heterozygous plant, of the offspring will have hairy stems, and of the offspring will have hairless stems.
Albinism (a) is a recessive condition. Normal pigmentation (A) is dominant. In order to have albinism you must have two recessive alleles.
Which circle graph shows the genotype probability when an albino female mates with a male that is homozygous dominant?
A baby with the recessive green eyes trait has two brown eyed parents.
Based on this information above, which of the following must be TRUE?
In humans, tongue rolling is dominant. NOT being able to roll your tongue is recessive.
Juliet has one gene for being able to roll her tongue and one gene for not being able to roll her tongue.
When Juliet has children, which of the following will be TRUE?
Chickens can have different types of feathers. Frizzled feathers curl toward a chicken’s head. Assume that feather type is determined by a single gene and that the allele for frizzled feathers is dominant over the allele for straight feathers. In a cross between two chickens with straight feathers, what percentage of the offspring can be expected to have frizzled feathers?
The inheritance pattern for hair color in a family is shown below.
Which child can ONLY have light hair color?
A model of the genetic control of fruit fly eye color is shown.
Which Punnett square represent a cross that would produce Sepia (tan) offspring?
