The probability of having both recessive traits is 1:16.
The probability that a given child will have PKU is 25%. This is because both parents are carriers of the recessive allele (heterozygous), so there is a 25% chance that they will each pass on the recessive allele, resulting in the child having PKU.
An example of a heterozygous chromosome is having one chromosome with a dominant allele and the other with a recessive allele for a particular gene. This can lead to different traits expressed depending on the dominant or recessive nature of the alleles.
Heterozygous means that it carries both dominant and recessive traits (as opposed to homozygous which carries only one) - the dominant trait is the one which is expressed (phenotype). A heterozygous trait can be expressed as Rr - "R" the dominant trait and "r" the recessive trait.
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.
A heterozygous genotype represents having two different alleles for a particular gene, with one being dominant and the other recessive. This results in the individual expressing the dominant trait while also carrying the recessive allele.
"Heterozygous" means having one copy each of the dominant and the recessive allele governing a particular trait."Dihybrid" means that you are following the inheritance of two traits ("di-" = 2).For example: in the peas that Mendel studied, round seeds (allele R) are dominant over wrinkled (r). So a heterozygous plant has the genotype Rr. Yellow seeds (Y) are dominant over green (y). In experiments following these two traits (seed shape and seed color) a dihybrid heterozygous individual therefore has the genotype RrYy.A dihybrid cross involves observation of two traits, e.g.RRYY x rryywhich would yield an F1 entirely made up of RrYy individuals.
The probability that a given child will have PKU is 25%. This is because both parents are carriers of the recessive allele (heterozygous), so there is a 25% chance that they will each pass on the recessive allele, resulting in the child having PKU.
Attached earlobes are a recessive trait. When one parent has attached earlobes and the other is heterozygous for free earlobes, the chances of any particular offspring having attached earlobes is fifty percent.
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.
The term is: heterozygous parents A monohybrid cross involves a single parent, whereas a dihybrid cross. The law of segregation requires having two or more generations to describe.
If you are heterozygous this means you carry both a dominant and recessive allele. if you are heterozygous for a recessive trait then you will have a dominant and recessive allele. example: let T represent tall and t represent short. a person with heterozygous for a recessive trait will have 'Tt'.
An example of a heterozygous chromosome is having one chromosome with a dominant allele and the other with a recessive allele for a particular gene. This can lead to different traits expressed depending on the dominant or recessive nature of the alleles.
Heterozygous means that it carries both dominant and recessive traits (as opposed to homozygous which carries only one) - the dominant trait is the one which is expressed (phenotype). A heterozygous trait can be expressed as Rr - "R" the dominant trait and "r" the recessive trait.
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.
Homozygous refers to having two identical alleles for a particular gene (e.g., two alleles for blue eyes). Heterozygous refers to having two different alleles for the same gene (e.g., one allele for blue eyes and one allele for brown eyes).
The plant with genotype PP is homozygous dominant, meaning it has two dominant alleles. The plant with genotype Pp is heterozygous, having one dominant and one recessive allele.
A heterozygous genotype represents having two different alleles for a particular gene, with one being dominant and the other recessive. This results in the individual expressing the dominant trait while also carrying the recessive allele.
