25%
2. select the best explanation for how gender is displayed within a normal human karyotype.
gender is determined from the 1st chromosome pair in a human karyotype
the 23rd chromosome pair displays gender as either xx for female or xy for male.
you cannot determine gender from a human karyotype
the 23rd chromosome pair displays an xy for female and xx for male
3. j indicates the allele for jagged-edge leaves.
j indicates the allele for smooth-edge leaves.
which statement about the offspring is correct if a cross between jj and jj was conducted?
0% will be heterozygous or homozygous dominant, and 100% will be homozygous recessive
50% will be heterozygous, 50% will be homozygous dominant, and 0% would be homozygous recessive
75% will be heterozygous, 25% will be homozygous dominant, and 0% will be homozygous recessive
50% will be heterozygous, 25% will be homozygous dominant, and 25% will be homozygous recessive
