Which parent determines the biological sex
Both types of sperm would have an equal chance of reaching the egg first.About half of his sperm will make a boy and half a girl.The sex of a baby is determined by two sex chromosomes inherited from both the genetic parents.The biological father determines the sex of a child.Which of the following is true about sexual identity?
It is odd, but the male.In a perfect world, it would all be up to chance.1 the x and y chromosomes are arguably the most fascinating members of the human genome:In fact, the y chromosome has a gene called sex determining region y. this is also known as sry.D) it is based mainly on social and cultural influences.
It is based mainly on social and cultural influences.It's determined by the father's sperm.The second to fourth digit ratio (digit ratio) is known to be sexually dimorphic;A father's sperm determines a baby's gender.It's a social and legal status, and set of expectations from society, about behaviors, characteristics, and thoughts.
Biological sex mitotic process meiosis male and female gametes gametocyte mtdna most adult mammals exhibit clear sexual dimorphism that manifests externally and internally.Trends in population sex ratios may be explained by changes in the frequencies of polymorphic alleles of a sex ratio gene.Usually, genetic testing is performed.The x and y chromosomes, also known as the sex chromosomes, determine the biological sex of an individual:
