Does your analysis support or refute mendels hypothesis of dominant and recessive inheritance?
You are from Kerr. The answer is on the textbook. The analysis does support the hypothesis because some of the offspring's genotype is heterozygous, as they have two different alleles. They do not have the recessive traits expressed, except in organisms that are homozygous recessive. You're so welcome.
What else can I help you with?
A single gene trait that has two alleles and that shows a simple dominant recessive pattern will result in?
A 3:1 phenotypic ratio (Mendelian inheritance).
Is a situation in which a dominant allele completely masks a recessive allele for a gene.?
If you have 2 dominant alleles, the gene will be dominant, if you have 2 recessive alleles, the gene will be recessive. But if you have 1 recessive and 1 dominant, the Dominant allele will mask the recessive one.
Explain how Mendel's particulate hypothesis is different from the blending hypothesis of inheritance?
Mendel showed in his experiments that inherited traits are not passed through the blending of inheritance theory. According to the blending of inheritance theory, an offspring's traits are a blend between the traits of the parent organisms. In Mendel's experiments however, he showed that this was not true, and that inheritance is actually based on genes, through the observation of recessive traits. He observed that an offspring could have a trait that neither of the parents had, which is now explained through both of the parents having the recessive gene for the trait, but not showing it because they are heterozygous dominant. There is a 25% chance that the offspring of two heterozygous dominant parents will produce a homozygous recessive offspring that will show the trait that neither of the parents shows.
What is the opposite of homozygous of dominant?
heterozygous recessive
What gene is masked if it is paired with a dominant gene?
The different forms of a gene are called alleles. In Mendelian genetics, a gene has a dominant allele and a recessive allele. The dominant allele masks the recessive allele if present. So there are two possible dominant genotypes: homozygous dominant, in which both dominant alleles are present; and heterozygous, in which one allele is dominant and the other allele is recessive. The only way to express a recessive trait is to have the homozygous recessive genotype.
Is the inheritance pattern of the BRCA1 gene dominant or recessive?
The inheritance pattern of the BRCA1 gene is dominant.
What are the four complex patterns of inheritance?
Autosomal dominant, Autosomal recessive, X-linked recessive and X-linked dominant
What are some patterns of inheritance in humans?
Autosomal dominant Autosomal recessive X linked recessive.
What are some patterns of humans inheritance?
Autosomal dominant Autosomal recessive X linked recessive.
When does a recessive trait dominant over a dominant trait?
A recessive trait cannot be dominant over a dominant trait. Dominant traits are always expressed over recessive traits in heterozygous individuals because they mask the expression of the recessive trait.
What is it called having a dominate and recessive allele?
Having a dominant and recessive allele is known as Mendelian inheritance, named after Gregor Mendel, the scientist who first described it. In this type of inheritance, the dominant allele masks the expression of the recessive allele in heterozygous individuals.
Which versions of genes are dominant over others in genetic inheritance?
In genetic inheritance, dominant genes are versions of genes that are expressed over recessive genes. Dominant genes mask the effects of recessive genes when they are present together in an individual's genetic makeup.
Is hereditary deafness recessive or dominant?
Hereditary deafness can be caused by both recessive and dominant genetic mutations. Autosomal recessive inheritance typically requires two copies of the mutated gene for deafness to manifest, while autosomal dominant inheritance only requires one copy of the mutated gene. There are also other forms of inheritance, such as X-linked and mitochondrial inheritance, that can cause hereditary deafness.
What are the states that some alleles are dominant and others are recessive?
Mendel's law of inheritance.
Is hirschsprung's disease dominant or recessive?
Hirschsprung's disease is typically non-Mendelian in inheritance, meaning it does not follow a simple dominant or recessive pattern. It is commonly associated with complex inheritance involving multiple genetic and environmental factors.
What is complte inheritance?
Complete inheritance refers to a situation where one allele is completely dominant over another in a gene pair, resulting in the dominant allele always being expressed in the phenotype, while the recessive allele remains hidden. This type of inheritance follows Mendel's laws of inheritance, where dominant traits mask the expression of recessive traits in an individual's phenotype.
Alleles that are neither dominant nor recessive produce an inheritance pattern known as .?
codominace
