Match each phenotype description to its corresponding sex chromosome genotype in humans. XO with SRY on an autosome XO XXXX XXY XYY Answer Bank phenotypically female with some abnormalities and overexpression of X chromosome genes phenotypically male with sterility and hypogonadism phenotypically male but karyotype indicates presence of only X chromosome female with Turner syndrome phenotypically male with an increase in average stature

Step 1
The genotypes given are XO with SRY on an autosome, XO, XXXX, XXY, and XYY. The SRY gene is responsible for initiating male sex determination. Normally, it is located on the Y chromosome. Show more…

Match each phenotype description to its corresponding sex chromosome genotype in humans. XO with SRY on an autosome XY with SRY deleted XXXX XXY XYY Phenotypically male but karyotype implies presence of only one X chromosome Phenotypically male with sterility and hypogonadism Phenotypically female but karyotype indicates presence of extra X chromosome

Identify the sexual phenotypes of the following genotypes in humans: $\mathrm{XX}, \mathrm{XY}, \mathrm{XO}, \mathrm{XXX}, \mathrm{XXY}, \mathrm{XYY}$
Match each type of inheritance with its definition. - Incomplete dominance - Polygenic inheritance - Sex-linked trait - Complete dominance - Co-dominance - Pleiotropy Dominant alleles are always present in the phenotype and recessive alleles are not present in the phenotype if a dominant allele is present. Multiple genes combine their effects to produce a single phenotype. A single gene produces multiple effects/phenotypes. Heterozygous individuals display a phenotype that is in between the dominant and recessive phenotypes. More than one dominant allele can be expressed in the phenotype. The gene for this trait is located on a sex chromosome (usually (X)).
