Gametes: The term "gametes" is another way of describing sex cells within organisms. Both males and females that reproduce sexually must produce gametes in order to conceive offspring. Answer and Explanation:1 In humans, the male gamete which is sperm is produced within the testes while the fe...
How can asexual reproduction in plants produce genetically identical offspring when meiosis occurs? Describe how events of meiosis and the fertilization of gametes result in genetic variation. In plants, what are produced by meiosis? a) gametogamy b) spores c) gametophytes d) sporophytes ...
Seeds are formed when the male gametes contained in pollen come in contact with the female gametes (ovules) through a process called pollination. Many plants rely on pollinator animals such as a bees or butterflies to transfer pollen from the anther of one flower to the stigma of another flowe...
A stamen is the male part of a flower, and together all stamens form the inner third whorl of a flower structure called theandroecium. Each stamen comprises a long tubular filament with a sac called theantherat the top.Pollengrains contain male reproductive cells or malegametesand are produ...
4. The life cycle of plants consists of a distinctalternation of generations. This means that plants have both the haploidgametophytewhich produces gametes and the diploidsporophyte. Depending on the species, the generations can occur simultaneously or successively. ...
<p>To find the frequency of pure round seeded pea plants in the F2 generation of a dihybrid cross, we can follow these steps:</p><p><strong>Step 1: Understand the Dihybrid Cross</strong> A dihybrid cross involves two traits, each represented by two allel
It is called anembryofrom 3-8 weeks (the embryonic period.) Then after 8 weeks, it is called afetus. If it continues to grow normally it can eventually become a baby. Terms Gonads-specialized sex organs where gametes are formed. In the male, the gonad is the testes, while in the fe...
<p><strong>Step-by-Step Solution</strong></p><p>1. <strong>Definition of Test Cross</strong>: A test cross is a genetic cross performed to determine the genotype of an individual with a dominant phenotype. It involves crossing the individual in question
Dioecy (Greek: διοικία "two households"; adjective form: dioecious) is a characteristic of a species, meaning that it has distinct individual organisms that produce male or female gametes, either directly (in animals) or indirectly (in seed plants). Dioecious reproduction is biparental...
Spores are released into the environment where they can germinate into haploid gametophyte plants. These plants produce male and female gametes. After fertilization, a new sporophyte develops within a seed. The seed eventually is released and the new sporophyte plant grows. Alternation of Generati...
