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>
Answer:
Refer to the attached image for correct labeling.
Explanation:
- The diagram is of a plant cell and its organelles.
- The nucleus houses the genetic material and controls all life processes.
- A plant cell contains one large vacuole in the center that stores water and nutrients.
- Chloroplast is the site for photosynthesis. It captures light and utilizes it and carbondioxide to produce glucose.
- Mitochondria are called the power house of the cell. Through a process called cellular respiration, they break down the glucose produced in photosynthesis into energy compounds such as ATP as well as oxygen and water.
- The endoplasmic reticulum is the site for protein sysnthesis. It contains two parts: the rough endoplasmic reticulum (RER) which contains ribosomes that synthesize proteins and the smooth endoplasmic reticulum (SER) which packages the proteins into transport vesicles.
- The nucleus contains the nucleolus that is the site for ribosome assembly.
- The cell membrane is a semi-permeable membrane that covers the cell and controls cellular transport.
- The cell wall is a hard, outer covering that protects the cell and maintains its structure and shape.
