I have a feeling it's when they are embryos.
In homo sapiens(humans), males are the heterogametic sex meaning their sex chromosomes are not the same(=XY) while females are homogametic(=XX).
Sex linked traits or x linked traits are traits whose genes are present on the X chromosome. So if there is a recessive mutation in those genes, males will express that recessive trait. Basically males express everything that’s on their X chromosome because they only have 1, but females have 2 which helps “hide” the mutation and to not express the particular recessive trait.
That is why sex linked traits are more evident in males in the population and an example of that would be colorblindness.
Hope this helps:)
Answer:
during cell division daughter cells are genetically identical to the mother cell
Explanation:
DNA replication refers to the biological process by which two identical DNA molecules are produced from one original DNA molecule. DNA replication generates two identical DNA molecules known as sister chromatids which separate during mitosis. After this process, both daughter cells contain identical genetic information as the parent cell. Moreover, DNA replication is semiconservative because the two daughter DNA molecules that are synthesized have one parent (original) DNA strand and one newly synthesized complementary strand.
