What Are Gametes In Dihybrid Cross Oct 8 2020 nbsp 0183 32 The fusion of the gametes causes the mixing of genetic material from both the parents that have undergone recombination thus making the offspring genetically competent to face adverse situations and survive Thus Option a Both A and R are true and R is the correct explanation for A is the answer for the given question
Sep 17 2023 nbsp 0183 32 During the pollen grain formation the generative cell divides to give rise to the two male gametes What is t Get the answers you need now Gametes are produced as a result of meiosis during which the chromosome number is reduced to half and each daughter cell receives half the set of chromosomes These gametes egg and sperm unite to form a zygote If both of them were diploid the zygote would have twice the number of normal chromosomes and the organism produced would be abnormal

After pollination the generative cell after entering into the pollen tube divide mitotically to form two non motile male gametes Hence one meiotic division and two mitotic division are required for the formation of fully mature male gametophyte from microspore mother cell in angiosperm Aug 24 2023 nbsp 0183 32 assertion A child has some characteristics of the father and some characteristics of the mother reason Fertilization of male and female gametes takes place inside the body of a female The assertion and reason are both correct When fertilization occurs the genetic material from the father s sperm and the mother s egg combines resulting in a child who inherits traits
May 10 2022 nbsp 0183 32 Concept Cell containing only one set of dissimilar chromosomes are called gametes Find Answer those questions Solution a Man produced two types of gametes are sperms and male hetrogamy b No a male child cannot be inherit X chromosome from his father because chromosomes of male child are X Y and female has only X X chromosomes that s Total types of gametes that an organism can produce is represented by 2n Here n number of genes for which the organism is heterozygous The given genotype AaBbCcDd is heterozygous for 4 genes and can make 24 16 types of gametes Thus the correct answer is option D

Feb 9 2020 nbsp 0183 32 Answer A gamete is formed by meiosis in the germinal cells Meiosis is also known as reductional division because after meiosis 4 daughter cells are produced with half of the total no of chromosomes present in each Therefore a gamete formed through this process has only 23 chromosomes and not 46 Hope it helps Oct 7 2023 nbsp 0183 32 Answer Different types of gametes with altered chromosome number that could possibly be produced are XX YY O Explanation In spermatogenesis Normally After Meiosis I X and Y chromosomes separate Sister chromatids of each chromosome do not split yet After Meiosis II The sister chromatids of X or Y split in this stage and each chromatid goes into a
