☆☆☆☆☆DNA doubles and produces sister chromatids before meiosis begins.
the chromosomes must replicate
a homozygous trait is when an offspring has either both dominant genes or both recessive genes from its parents. a heterozygous trait is when an offspring has both dominant and recessive genes. for example: a long-tailed cat is dominant and a short-tailed cat is recessive. the long-tailed cat (homozygous dominant) had offsprings with the short-tailed cat (homozygous recessive). by doing the punnett square, 100% of their offspring will be heterozygous.
Color blindness is a recessive sex linked trait.
Ill tell you when your older
Cause attached earlobes are the dominant trait. Unattached earlobes are reccessive.
Only men have them.
Scientists discovered chromosomes in DNA
mitosis only has to do with celluar reproduction
meiosis has to do with sex cells reproducing
Mitosis creates new cells that are used for development, repair, asexual reproduction and growth. Meiosis creates cells in order for organisms to reproduce sexually.
