Define gamete.

Expert Solution & Answer

Summary Introduction

To determine:

The definition of gamete.

Introduction:

A gamete is the cell containing the genetic information that is forms in human reproductive organ which fuses with other sex gamete at the time of fertilization.

Explanation of Solution

The reproductive system ensures the survival of human species by producing and nourishing gametes in the reproductive organ (gonad).

In humans there are two types of gametes:

Ova/egg: It is produced by female gonad (ovaries) present in adult females, containing single set of chromosome. Every month one immature gamete called as oocyte is produced by single ovary under the influence of hormones and later turns into ova at the time of fertilization.
Sperm: It is the male gamete produced by male gonad (testis) present in adult males with single set of chromosome. About half a billion sperms are produced every day by adult male and during the ejaculation sperms are mixed with the secretion of accessory glands and forms semen which is discharged from male reproductive organ.

Question #3: In the KeyGene paper, the authors state that it would be useful if pollen from an apomict would transmit apomixis-inducing genes to the female in the cross (assuming the pollen is viable). Assuming there was just one gene conferring gametophytic obligate apomixis, and that the two parents are inbreds, what would be the consequences of such a cross if: a) The apomixis was a dominant trait? Indicate the genotypes and phenotypes (apomict or non- apomict) of the parents, F1 and F2 generations. Remember to include the expected genotypic and phenotypic ratios (or percentages) in the F1 and F2 generations, and to position the female first (left side) in the parental cross. b) The apomixis was a recessive trait? Indicate the genotypes and phenotypes (apomict or non- apomict) of the parents, F1 and F2 generations. Remember to include the expected genotypic and phenotypic ratios (or percentages) in the F1 and F2 generations, and to position the female first (left side) in the…

Question #5: Assume that two genes are identified that confer gametophytic facultative apomixis in soybean. The genes show independent assortment. Recessive alleles at both loci are required for the facultative apomixis. Facultative apomixis is triggered when the temperature at pollination is above 20 degrees C. At temperatures below 20 degrees C, all reproduction is sexual, independent of genotype. A facultative apomict male, capable of producing viable pollen, was crossed with a sexually reproducing female. Assuming the parents are completely inbred, what are the predicted phenotypic ratios (apomict: non-apomict) for the F1, F2, and DH (F1-derived) generations at each of the following temperatures*: a) 15°C? b) 25°C? *for full credit, show crosses and genotypes where appropriate. Remember to position the female first (left side) in the cross. Type your answer here:
