How is a zygote formed? How is DNA related to reproduction? How does Taenia saginata sexually reproduce? How does gene flow contribute to speciation? Why did Mendel use cross-pollination to study inheritance? What are seed plants that produce flowers and fruits?
If a human gamete that is missing a chromosome participates in fertilization with a normal human gamete, what will be the result? How many chromosomes will the zygote have? The diploid number of chromosomes in humans is 46. What is the haploid number? If a cell ha...
Assertion : The method of development of embryo sac from a single functional megaspore is termed as monosporic development. Reason : In monosporic (Polygonum) type of embryo sac development, usually the megaspore which is situated towards micropylar end remains functional. ...
Step-by-Step Text Solution:1. Definition of Asexual Reproduction: Asexual reproduction involves only one parent organism. In this process, offspring are produced without the fusion of gametes.2. <stro
The process by which the gametes of two parents fuse to form a zygote is referred to as sexual reproduction. Human reproduction: The male and female reproductive organs are in charge of procreation. Sperm is produced in a male's testes, and eggs are produced in a female's ovary. ...

There are centers in which it is transferred in the zygote stage, on day 2 of embryonic development or in the morula stage. However, the most common practice today is to carry out the embryo transfer on day 3 (in the early embryonic stage) or on day 5 (in the blastocyst stage). Desp...
zygotene spermatocytes; P, pachytene spermatocytes; Sa and Sb, early spermatids; Sc and Sd, late spermatids. There is, however, a chaotic placement of these various stages of spermatogenesis in a random mix in humans rather than in an orderly wave as in other animals along the semi...
Once the zygote starts to grow, the ovary begins developing into a fruit and the ovules begin to form seeds. The outside wall of the ovary and pistil becomes the skin of the fruit, or in some cases like the apple and pear, there develops a fleshy and edible material outside the ovary...
