∙ 11y agoThey are carriers because they are heterozygous for the trait, so they do not have the recessive disorder but can pass on a recessive allele to an offspring. If both parents are carriers, then both may pass on their recessive alleles to an offspring, resulting in that offspring having the recessive disorder.

True or False In heterozygous individuals only the recessive allele is expressed?
In heterozygous individuals, only the dominant allele is expressed. The recessive allele is present, but not expressed
When inheritance of a particular trait follows a pattern of what individuals that are heterozygous for the trait have the same phenotype or physical characteristic as individuals who are homozyg?
This type of inheritance represents alleles at the same locus where one is recessive to the other. The dominant phenotype occurs in all heterozygous offspring as well as the homozygous dominant offspring. This yields a 3:1 phenotype and a 1:2:1 genotype.
What does does heterozygous mean?
Heterozygous means that you are carrying 1 dominant trait and 1 recessive trait.If an allelic pair has one dominant and other recessive gene it is called heterozygous.
What heterozygous mean?
Heterozygous means that you are carrying 1 dominant trait and 1 recessive trait.If an allelic pair has one dominant and other recessive gene it is called heterozygous.
What is an organism with one dominant and one recessive gene for a trait?
that organism is a heterozygous one which contain the traits of recessive as well as dominant genes.

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.
True or False In heterozygous individuals only the recessive allele is expressed?
In heterozygous individuals, only the dominant allele is expressed. The recessive allele is present, but not expressed
What is the probability of 2 heterozygous individuals producing a homozygous recessive offspring?
25%
How is sickle cell alleles maintained through natural selection?
Heterozygous induviduals pass the dominant and recessive alleles to offspring

How is the sickle cell allele maintained through natural selection?
Individuals with two recessive alleles have very high rates of reproduction.

How would a recessive trait show up in a cross between two individuals with a dominant phenotype?
If both the individuals are heterozygous dominant then the probability of recessive (homozygous) phenotypic offspring would be 1:4
How is the sickle cell maintained through natural selection?
Heterozygous individuals pass the dominant and recessive alleles to offspring.
How is the sickle allele maintained through natural selection?
Heterozygous individuals pass the dominant and recessive alleles to offspring.
Why are heterozygus individuals called carriers for non-sex-linked and X-linked recessive patterns of inheritance?
Aa. This is the heterozygous condition. Two alleles, one of which is dominant and masks the expression ( to varying degrees ) of the other allele. 'A' dominant and 'a' recessive. So, if the trait in question is the recessive allele the dominant allele masks its expression and the organism is a ' carrier ' of the trait and can pass it on to progeny.
