1 What is the difference between homozygous and heterozygous?
Homozygous refers to having two identical alleles for a trait, while heterozygous refers to having two different alleles for a trait. In other words, homozygous individuals have either two dominant or two recessive alleles, while heterozygous individuals have one dominant and one recessive allele.
Is huntington disease homozygous or heterozygous?
Huntington disease is autosomal dominant, meaning that individuals who inherit one copy of the mutant allele from either parent will develop the disease. Thus, individuals with Huntington's disease are heterozygous for the mutant allele. Homozygous individuals would not survive past a certain age due to the severity of the disorder.
If you have two copies of the same allele are considered to be for that traits whereas if you have two different alleles you are considered to be for that trait?
Having two copies of the same allele for a trait is termed homozygous, while having two different alleles for a trait is heterozygous. Homozygous individuals will display the trait determined by that allele, while heterozygous individuals may express either allele's trait, depending on dominance relationships.
Differentiate the terms homozygous and heterozygous?
Homozygous is a description of alleles that are the same (HH,hh): either both dominant or both recessive. Heterozygous is a description of alleles that are different (Hh): one dominant, one recessive.
What is the difference between a homozygous dominant homozygous recessive and heterozygous individual?
They are the same
What is the probability of 2 heterozygous individuals producing a heterozygous recessive offspring?
The probability is 50%. There are four probabilities: dominant homozygous, recessive homozygous, or heterozygous.
What is the differences between homozygous dominant and homozygous recessive and heterozygous?
Homozygous dominant individuals have two copies of the dominant allele for a trait, homozygous recessive individuals have two copies of the recessive allele, and heterozygous individuals have one copy of each allele. Homozygous dominant and heterozygous individuals will express the dominant trait, while homozygous recessive individuals will express the recessive trait.
What crosses will only produce heterozygous offspring?
A cross between two individuals that are homozygous for different alleles will only produce heterozygous offspring. This is because each parent can only donate one type of allele, resulting in all offspring being heterozygous for that particular gene.
1 What is the difference between homozygous and heterozygous?
Homozygous refers to having two identical alleles for a trait, while heterozygous refers to having two different alleles for a trait. In other words, homozygous individuals have either two dominant or two recessive alleles, while heterozygous individuals have one dominant and one recessive allele.
How can one determine whether an individual is homozygous or heterozygous using gel electrophoresis?
In gel electrophoresis, an individual can be determined to be homozygous or heterozygous by looking at the number and size of bands on the gel. Homozygous individuals will show only one band, while heterozygous individuals will show two bands of different sizes.
What is the probability of 2 heterozygous individuals producing a homozygous recessive offspring?
25%
Is asthma homozygous or heterozygous?
heterozygous
Can you please distinguish homozygous and heterozygous individuals?
Homozygous individuals have two identical alleles for a particular gene (e.g., AA or aa), while heterozygous individuals have two different alleles for the same gene (e.g., Aa). Homozygous conditions often result in specific traits, while heterozygous conditions can lead to a blending or mix of traits from each allele.
When two alleles of a pair are identical it is a condition if the two alleles are different this is a condition?
When two alleles of a pair are identical, it is referred to as homozygous. When the two alleles are different, it is referred to as heterozygous. Homozygous individuals have two identical alleles (e.g., AA or aa), while heterozygous individuals have two different alleles (e.g., Aa).
What is the difference between homozygous and herterozygous?
Homozygous refers to having two identical alleles for a particular gene, while heterozygous means having two different alleles for the same gene. Homozygous individuals can be either homozygous dominant (two dominant alleles) or homozygous recessive (two recessive alleles), while heterozygous individuals have one dominant and one recessive allele.
What are the genotype a of a homozygous and a heterozygous tall pea plant?
homozygous- TT; heterozygous- Tt :)
How would selection against heterozygous individuals over many generations affect the frequencies of homozygous individuals?
If heterozygous individuals are not favored, then the frequency of heterozygous individuals will decrease as the frequency of homozygous individuals increase. This can be shown using the Hardy-Weinberg equation for allele frequencies in a population: p2 + 2pq + q2 = 1 where q2 & p2 are the frequencies of the two different homozygous individuals (eg. aa and AA) and 2pq is heterzygous (eg. Aa). As the equation shows, if 2pq decreases, the other two variables must increase to compensate.
