What else can I help you with?
The term true-breeding strain refers to a genotype?
True-breeding strain refers to a genotype that, when self-pollinated or crossed with another organism with the same genotype, always produces offspring with the same phenotype. This means that the trait is homozygous and will be consistently expressed in the offspring generation after generation.
How do you determine a phenotype when the genotype is different but the phenotype is the same?
You look at the offspring. Offspring of a heterogenous match are going to have different phenotype percentages than those of a homogenous match.
What is the phenotype of a rooster with the genotype FBFW?
the offspring will have both black and whit feathers.
What is the genotype and phenotype ratios for a homozygous dominant female and a homozygous resessive male?
When a homozygous dominant female (genotype AA) is crossed with a homozygous recessive male (genotype aa), all offspring will inherit one dominant allele from the mother and one recessive allele from the father, resulting in a genotype of Aa for all offspring. The phenotype ratio will show all offspring displaying the dominant trait. Thus, the genotype ratio is 100% Aa, and the phenotype ratio is 100% expressing the dominant trait.
What is the genotype of the offspring that do not share the parents phenotype?
If both parents have the same phenotype, but the offspring did not share that phenotype, then it is likely that the parents have a dominant phenotype, but the offspring has a recessive phenotype, which means that the offpring's genotype would be homozygous recessive, and it's parents' genotypes would be heterozygous. For example, the parents may both have the genotype Bb, which gives them black fur. Approximately 25% of their offspring should have the genotype bb, which gives them the phenotype of white fur.

What was the genotype of the offspring that did not share the parent's phenotype?
The genotype of the offspring that had the same phenotype as the parents is rr or wrinkled. The phenotype for the seed shape of both parent plants is round.
What was the genotype of the offspring the did not share the parents' phenotype?
If both parents have the same phenotype, but the offspring did not share that phenotype, then it is likely that the parents have a dominant phenotype, but the offspring has a recessive phenotype, which means that the offpring's genotype would be homozygous recessive, and it's parents' genotypes would be heterozygous. For example, the parents may both have the genotype Bb, which gives them black fur. Approximately 25% of their offspring should have the genotype bb, which gives them the phenotype of white fur.
What describes organisms or genotypes that are homozygous for a specific trait that always produce offspring of the same phenotype?
Organisms or genotypes that are homozygous for a specific trait and always produce offspring of the same phenotype are said to be true breeding. This means that when bred with another organism of the same genotype for that trait, all offspring will display the same characteristic.
What was the phenotype of the offspring that did not share of the parents phenotype?
If both parents have the same phenotype, but the offspring did not share that phenotype, then it is likely that the parents have a dominant phenotype, but the offspring has a recessive phenotype, which means that the offpring's genotype would be homozygous recessive, and it's parents' genotypes would be heterozygous. For example, the parents may both have the genotype Bb, which gives them black fur. Approximately 25% of their offspring should have the genotype bb, which gives them the phenotype of white fur.
Which of the following statements about a gene that shows maternal effect inheritance is true?
A gene that shows maternal effect inheritance is one where the phenotype of the offspring is determined by the genotype of the mother, rather than the offspring's own genotype. This means that even if the offspring carries a certain genetic variant, it will only display the phenotype associated with the mother's genotype.

Breeding an individual of dominant phenotype with a homozygous recessive individual to determine the individuals genotype?
