At a hypothetical locus, a man’s genotype is Aa. What proportion of his gametes would be expectedto receive the A allele?a.1/3b.
nydimaria [60]

Answer: The correct answer is 1/2

Explanation:

Based on Mendel's 2nd law - the law of independent assortment of genes - each character behaves as a separate unit and is INHERITED independently of any other character.

So, Aa will separate in two alleles "A" and "a". And by the law, each will be received by the gametes in equal rate of 50:50 i.e 1/2.

So for"A" allele, it is 1/2

Which statement concerning the reproductive cells in the diagram below is correct?
alexandr1967 [171]

The gametes that are produced contain half the actual number of chromosomes that are found in the organism.

Option C

<h3><u>Explanation:</u></h3>

The gametes are the units of sexual reproduction. These gametes are formed from the gamete mother cell by the process of meiosis. Meiosis actually convert a diploid cell into a haploid cell by reducing the chromosome number to half. So the genetic information of the gamete is also half to that of the other cells of that organism.

When two gametes fuse, they actually complete the full set of chromosomes and form a new organism which contains the characters according to the dominant and recessive basis. So offsprings are not completely similar to any of the parents.

Plantae: Autotrophic, Multi- or Monocellular, have cell walls as well as a membrane, have a chloroplast making the characteristic green color and to capture sunlight for photosynthesis. Break down generated glucose into it's components.

Animalia: Heterotrophic, Multi- or Monocellular, have a cell membrane made of a phospholipid bilayer, and many mitochondria to aid with movement energy. Feed on plants or other animals. Eukaryotic cells.

Fungi: Heterotrophic, most Multicellular, have a rigid cell wall made of chitin, specialized cells to aid with decomposition of dead organic matter. Eukaryotic cells.

Protista: Can be plant-like, animal-like, or fungus-like. Most are single-celled, may be chemosynthetic or photosynthetic. Eukaryotic cells.

Archeabacteria: Prokaryotic. Do not have nuclei or membrane-bound organelles. Move around using a flagellum to propel itself. Lives in mainly fluid environments (air, water). Separated from Eubacteria due to it's high tolerance of extreme conditions, such as high salinity, no oxygen, burning heat, or freezing cold. Can be chemosynthetic or anaerobic, as well as aerobic.

Eubacteria: Normal, everyday bacteria. Prokaryotic, chemosynthetic, anaerobic, or aerobic. Do not have nuclei or membrane-bound organelles. Mobile using a flagellum to propel itself.
