Perform a test cross of two homozygous individuals base on a hypothesis, I usually just guess to begin with.
Hypothesis:
Example: Purple x White
all Purple
Then cross the F1 generation (those guys above)
Purple x Purple
you get the fallowing ratios if the purple allel is dominant
3/4 Purple 1/4 white
Usually you are given a number of offspring for problems like this so lets
Example: purple x white
F1 all purple would mean purple is dominant, you can take it further too.
F2 100 offspring= 25 white and 75 purple
Note: In real life numbers wont be nice and even like this so you may have to do some chi squared analysis to check your hypotheses.
What else can I help you with?
What are the four complex patterns of inheritance?
Autosomal dominant, Autosomal recessive, X-linked recessive and X-linked dominant
Based on the pedigree above how many offspring from this cross had the recessive phenotype?
To determine the number of offspring with the recessive phenotype from the pedigree, you would need to analyze the specific symbols and relationships depicted in the pedigree chart. Typically, the recessive phenotype is represented by a specific shape or shading. By counting the individuals displaying that phenotype among the offspring shown in the pedigree, you can arrive at the total number of offspring with the recessive trait. If the pedigree is not provided, I cannot give an exact number.
What is the genotype of a person who is a carrier of a autosomal recessive trait?
The genotype of a person who is a carrier of an autosomal recessive trait is typically heterozygous, meaning they carry one copy of the recessive allele and one copy of the dominant allele for that trait. This would be represented as Aa, with the lowercase "a" representing the recessive allele.
Is the maple syrup disease sex-linked?
Yes, maple syrup urine disease (MSUD) is an autosomal recessive genetic disorder, not a sex-linked disorder. It is caused by mutations in genes on autosomal chromosomes, which both males and females can inherit equally.
Is cooley anemia sex-linked trait or autosomal trait?
Cooley's anemia, also known as beta-thalassemia, is an autosomal recessive genetic disorder. This means that both copies of the gene must be mutated in order for the disease to be present. It is not a sex-linked trait.
What are some common challenges faced when analyzing autosomal recessive pedigree problems?
Some common challenges when analyzing autosomal recessive pedigree problems include incomplete family medical history, consanguinity within the family, small family size, and the presence of other genetic disorders that may complicate the analysis.
Is cystic fibrosis an autosomal disease?
Yes, cystic fibrosis is an autosomal recessive disease.
What kind of diseases are the most common genetic diseases (?
Recessive Autosomal
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.
Can a human pedigree be used to detect a recessive trait?
Yes, a human pedigree can be used to detect a recessive trait by tracking the inheritance pattern of the trait within a family. Patterns such as multiple affected siblings, skip generations, and consanguinity can help identify recessive trait inheritance. Pedigree analysis can reveal carriers of the trait even if they do not show symptoms.
How many cases of SCID are autosomal recessive?
About 40% of SCID cases are inherited from the parents in an autosomal recessive pattern.
Is pku disease an autosomal dominant trait?
It is an autosomal recessive trait.
What are the four complex patterns of inheritance?
Autosomal dominant, Autosomal recessive, X-linked recessive and X-linked dominant
What it Autosomal recessive?
gene that is not strong
What are the probable mode of inheritance from a pedigree diagram showing phenotypes?
The modes of inheritance are y-linked, x-linked, and mitochondrial. Inherited traits can then be recessive, dominant, or autosomal depending on how they are inherited.
Is Zellweger syndrome dominant or recessive?
Zellweger syndrome is autosomal recessive.
