WebJun 30, 2024 · (a) They are divided equally between terrestrial and aquatic species. (b) Many produce large numbers of gametes to ensure successful reproduction. (c) The behaviours associated with mating are often highly synchronized. (d) The probability of any one egg being fertilized and developing into an adult can be low. Answer WebFour different types of eggs are produced by a double heterozygous female fly, each of which combines with a sperm from the male tester fly. Four different phenotypic (appearance-based) classes of offspring are produced in this cross, each corresponding to a particular …

What animal produces male gametes by mitosis?

WebGametes ( sperm and ova) are haploid cells. The haploid gametes produced by most organisms combine to form a zygote with n pairs of chromosomes, i.e. 2 n chromosomes in total. The chromosomes in each pair, one of which comes from the sperm and one from the egg, are said to be homologous. WebIn sexual reproduction new organisms are produced from the fusion of a male sex cell with a female sex cell. This fusion of gametes is called fertilisation. Sex cells are also known as... northern co-op meat company

Gametophyte Structure and Sporophyte Generation

WebThe gametes produced by the F 1 individuals must have one allele from each of the two genes. For example, a gamete could get an R allele for the seed shape gene and either a Y or a y allele for the seed color gene. It cannot get both an R and an r allele; each gamete can have only one allele per gene. WebJul 20, 1998 · Gametes are formed through meiosis (reduction division), in which a germ cell undergoes two fissions, resulting in the production of four gametes. During fertilization, male and female gametes fuse, producing a diploid (i.e., containing paired chromosomes) zygote. WebThe gametophyte generation creates gametes. These gametes are produced by gametangia. These gametes are then transferred between plants or spread into the environment. When a gamete encounters a gamete of the opposite sex, it fuses with it to form a zygote which eventually becomes a sporophyte. northern contracting inc il
