Is the female indicated a heterozygous or homozygous carrier?

Transcribed Image Text. While examining a human female, you discover that she has 44 autosomes and two sex chromosomes, an X and a Y. This may lead you to suspect that there is a mutation within this individual's SRY gene X chromosome recessive alleles autosomes. …

What is a carrier of disease?

What is the genotype of a carrier of a recessive disorder?

Only individuals with an aa genotype will express a recessive trait; therefore, offspring must receive one recessive allele from each parent to exhibit a recessive trait.

What is the genotype of the carrier mother?

The genotype of the carrier is Ff (one dominant non-disease gene, F, and one recessive, CF gene, f).

What is female genotype?

Genotypic sex refers specifically to an individual's two sex chromosomes. Most people have either two X chromosomes (genotypic female) or an X and a Y chromosome (genotypic male).

What is an autosomal recessive disorder?

In an autosomal recessive disorder, one mutated gene is inherited from each parent. The parents each carry one mutated gene and one normal gene for the disease, although the parents do not have the disease.

What is a carrier in genetics?

A carrier is an individual that has a change in one of those two copies. When two individuals that are carriers meet and produce an offspring, if that offspring inherits the changed or misspelled copy of the gene from each parent, that individual, that offspring, will have a recessive disorder and will have clinical features of a recessive disorder.

What is a carrier in medical terms?

A carrier is an individual who carries and is capable of passing on a genetic mutation associated with a disease and may or may not display disease symptoms.

What is a carrier?

=. A carrier is an individual who carries and is capable of passing on a genetic mutation associated with a disease and may or may not display disease symptoms.

What is a genetic carrier?

Genetic carriers are individuals who carry. one copy of a recessive mutated allele and one normal copy. FEEDBACK: Genetic carriers have one copy of a recessive mutated allele and do not show signs of the disease. Individuals with one or more copies of a dominant mutated allele would show signs of the disease.

What is it called when two alleles are identical?

The individual has two copies of the same allele for the gene. FEEDBACK: When the two alleles for a gene are identical, the individual is said to be homozygous. If the two alleles are different, the individual is referred to as being heterozygous for that gene.

How many chromosomes are in a human karyotype?

two X chromosomes. FEEDBACK: A normal karyotype will show 22 homologous pairs of autosomes. In addition, a female would have two X chromosomes and a male would have one X chromosome and one Y chromosome. In humans, the presence of an SRY gene.

What is the SRY gene?

FEEDBACK: The SRY gene is a sex-linked gene on the Y chromosome that functions as a master sex switch, which commits a developing embryo to male. The Y chromosome in humans is. normally found in single copy. FEEDBACK: The Y chromosome is always found as a single copy in males. Human males are XY.

Can girls inherit recessive X-linked disorders?

There is a misconception that girls cannot inherit recessive X-linked disorders. Girls can in fact inherit these disorders, but at a lower rate than boys. The following choices give the genotypes for pairs of mothers and fathers. Which pair of parents could have a daughter with the recessive disorder a?

Which chromosome is X linked?

X-linked disorders. Duchenne muscular dystrophy, hemophilia, and fragile X syndrome are all X-linked disorders whose genes are found on the X chromosome. Because males only have one X chromosome, they exhibit the disease significantly more frequently than females.

What is X-linked disorder?

X-linked disorders. Duchenne muscular dystrophy, hemophilia, and fragile X syndrome are all X-linked disorders whose genes are found on the X chromosome. Because males only have one X chromosome, they exhibit the disease significantly more frequently than females.

What is Marfan syndrome?

Marfan syndrome occurs when an individual inherits one or two copies of the defective FBN1 gene. Marfan syndrome is caused by a defect in FBN1 gene located on chromosome 15. The gene normally encodes the fibrilllin-1, which is important for the elasticity and appropriate growth of connective tissue.
