Haploid gametes produced in males are called sperm. O True False

A scientist working in an IVF (in vitro fertilization) clinic mistakenly produced a human zygote with 45 chromosomes. What biological process could explain how this happened? Group of answer choices failure of an egg to complete meiosis II failure of the egg nucleus to be fertilized by the sperm a non-disjunction in meiotic anaphase occurring in either an egg or sperm incomplete cytokinesis during spermatogenesis after meiosis I 2. When Mendel crossed in his P generation a yellow-seeded and green-seeded pea plants, all the offspring were yellow seeded. When he took these F1 yellow-seeded plants and crossed them with the original yellow-seeded plant from the P generation, what genotypic ratio was expected? Group of answer choices 1:2:1 3:1 1:1:1:1 1:1

O C The end product is four gametes. O D Meiosis only occurs in reproductive structures. O E It involves two rounds of division.

Gamete formation results in ____.   the pairing of homologous chromosomes   offspring that are genetically distinct from each other   offspring that are genetic clones of the present   asexual reproduction   the fusion of gametes
