True or False. By using cuttings, exact genetic characteristics can be maintained.​

Biology
1 answer:
Brrunno [24]3 years ago
7 0

Answer:

It is true to say that by using cuttings, exact genetic characteristics can be maintained, because the cuttings retain the same genetic information about the plant from which they were extracted.​

Explanation:

Cuttings are buds or branches extracted from a plant to obtain a plant of the same species, through a type of asexual reproduction.

Once separated from the "progenitor" plant, the cutting is provided with a suitable medium for growth, and will have the possibility of growing roots, developing and growing as an independent plant, with the same genetic characteristics of the original plant, as if it were a clone.

In this reproductive process, man intervenes.

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>
