Reason -

There is no link of genetic engineering with the creation of deadly weapons and those too physical weapons.

The common ethical concerns related to biotechnology experiments consists of the following –  

a) Leaking of genetic information of an individual

b) Creation of harmful species

what function does the electron transport chain play in the light- dependent cycle of photosynthesis ?
romanna [79]

Answer:

The light-dependent reactions use light energy to make two molecules needed for the next stage of photosynthesis: the energy storage molecule ATP and the reduced electron carrier NADPH. In plants, the light reactions take place in the thylakoid membranes of organelles called chloroplasts.

For this week's CRQ, you are to design your own genetic cross between a female and a male. Be sure to include each of the follow
svp [43]

Answer and Explanation:

Punnett squares are illustrations that display the product of hybrid trait crosses by genetic breeding. Established parent genotypes and phenotypes are used and are usually compatible with Mendelian ratios and inheritance. The phnomenon influencing this behaviour is the

  • Law of Segregation,
  • Law of Independent assortment
  • and Dominance

For this cross...

Assuming Widow's peak= dominant

<u> 1. What are the dominant and recessive traits in cross?</u>

Parent generation or P generation:

gametes: Ww → Widow's peak dominant (W), No Widow's peak recessive (w)

<u>2. Is the male homozygous dominant, homozygous recessive, or heterozygous?</u>

Heterozygousity describes the allelic makeup; these traits are made of two different forms of the same gene.

Male: Ww  →  with the W.peak;  

(Thus, with both W and w this is a heterozygous trait)

<u>3. Is the female homozygous dominant, homozygous recessive, or heterozygous?</u>

However, homozygous traits are made up of the same forms of the gene called alleles.

Female: ww → without the W.peak  

(Thus, with both w ad w this is a homozygous trait)

<u>1. genotypes and phenotypes for parent and offspring...</u>

<u></u>

Assuming heterozygousity of the male , for the cross

P generation:                          Ww× ww

                            Widow's peak  ×No Widow's peak  

F1 generation:

  • genotype:                       Ww × ww       ...(from punnet square)
  • phenotype:          2 with the W.peak; 2 without

<em>∴ 50% are genotypically heterozygous while 50% is homozygous , 2 with the W.peak; 2 without </em>
