Human Development-Sex Variations Individuals may acquire chromosomal sex variations, where the number and type of sex chromosomes are not average. A list of some of these variations is below. For each one, predict if the zygote would be assigned male or female or intersex at birth. Later, compare your predictions to the actual phenotypes.

Look carefully at the pedigrees below and:
1) indicate whether the transmission appears autosomal or
sex-linked
2) indicate whether the transmission appears dominant or
recessive
3) provide at least two characteristics for each that support
your conclusion.
In general, the following characteristics suggest (but do not prove) specific inheritance patterns: Autosomal recessive inheritance: -affected individuals can be born to unaffected parents -if both parents are affected, all children are affected -observable effect of relatedness (consanguinity) -horizontal" inheritance: trait appears at...
