43.7 g of irons it’s completely used in the reaction above, how many grams of oxygen are involved in the reaction

the answer to the blank provided is “an autosomal gene that is required for the expression of genes on the x chromosome”.

testis-determining factor, abbreviated as td, which is more popularly known as sex-determining region y or sry protein, is a dna-binding protein or  gene-regulatory protein/transcription factor, encoded by the  sry gene. it is the gene responsible for the initiation of male gender determination in humans.

answer: b. is a blend of the genetic material of its parents 

sexual reproduction  is where two  distinct types of reproductive  cells  called  gametes  fuse together. they are known as egg or a female's large  ovum and a male's sperm. each gamete contains half the number of genetic materials or chromosomes  of the organism. the two gametes fuse and their genetic material of parents blend during  fertilization to produce  dna replication  and the creation of a single-celled  zygote  which now includes genetic material from both gametes. the process of blending of genetic material of parents is called genetic recombination.
