For a person with the genotype Dd, which of the following will be TRUE?
In cockatiel birds, the gray color cockatiel is dominant over the yellow color. A heterozygous gray cockatiel bird is mated with a heterozygous gray cockatiel bird. What percent of their offspring will have yellow feathers?
In a rare species of tropical sea turtle, red shells are dominant to green shells. A homozygous red-shelled sea turtle falls in love with a homozygous green-shelled sea turtle. What percent of their offspring will have red shells?
In dogs, being smelly is dominant to not being smelly. If a hybrid dog mates with a dog who is pure recessive, what percent of their offspring will be smelly?
Chickens can have different types of hackles (the feathers on the back of their head). Assume that feather type is determined by a single gene and that the allele for short hackles is dominant over the allele for long hackles. In a cross between a male chicken that is heterozygous and a chicken that is pure dominant, how many of the chicks will be born pure dominant?
In humans, the ability to taste PTC is dominant. NOT being able to taste PTC is recessive.
Juliet is homozygous dominant (PP) for tasting PTC.
When Juliet has children, which of the following will be TRUE?
Blue eyes are recessive to green eyes. A child is born heterozygous for green eyes. What genotypes did the parents have to have a heterozygous child?
Achondroplasia (A) is a dominant condition, a primary feature is dwarfism. Normal condition (a) is recessive. In order to have a normal condition you must have two recessive alleles.
Which circle graph shows the genotype probability when a heterozygous female mates with a male that is homozygous recessive?
In dogs the allele for pointy ears (P) is dominant over the allele for floppy ears (p). The phenotypes for each trait are shown below in the picture.
The probability (% chance) that the offspring will have floppy ears if both parents are heterozygous is
In tomato plants, short stems are present in tomato plants that are homozygous recessive for that trait. Plants that have the dominant trait have long stems.
If a homozygous dominant plant mates with a heterozygous plant, of the offspring will have long stems, and of the offspring will have short stems.
In giraffes, short necks are recessive to long necks. Two long neck giraffes, who are both heterozygous for the neck length trait, mate. What is the probability that they will have an offspring with a long neck length?
In teachers, giving homework is dominant to not giving homework. A teacher who is pure dominant for giving homework falls in love with a teacher who is hybrid for the trait. What is the probability that they will have offspring who are hybrid?
In humans, dimples are dominant to no dimples. If a female who is homozygous for having dimples were to mate with a male who does not have dimples, then what would be the probability that their offspring would have dimples?
In humans, having free earlobes is considered a dominant trait, while having attached earlobes is considered recessive. A female who is heterozygous for free earlobes mates with a man who is also heterozygous for free earlobes. What percent of their offspring would be homozygous for having free earlobes?
Possible phenotypes and genotypes of eye color are shown below.
Which table shows the expected phenotypes of offspring resulting from a green eyed father and a hybrid brown eyed mother?
