A true-breeding plant with inflated pods and yellow pods is crossed with a plant that has constricted and yellow pods. Draw a
xenn [34]

Answer:    Sysy ×  Sysy  i.e. <em>all are genotypically heterozygous, inflated, and yellow</em>

Explanation:

Punnett squares are a diagrammatic means of determining traits of hybrid offspring produced via crosses in genetic breeding. The parental genotypes and phenotypes are usually known, and these typically follow standard Mendelian ratios and inheritance.

Mendelian genetics focus on trait inheritance, or heritability. These traits are packaged out into its own gamete, inherited by themselves and often show dominance, where one's effect may mask those of another trait.

These are called the Law of Segregation, Independent assortment and Dominance respectively.

For this cross...

Parent generation or P generation:

gametes: Y → pod color green dominant (Y), yellow recessive (y)

                S→ pod size; inflated dominant (S), constricted recessive (c)

Assumptions...

  • True breeding plants are homozygous, with identical sets of alleles
  • The other parent is heterozygous, as it was not said to breed true

P generation:                          SySy  × sysy

<em>                             yellow,  inflated    </em>× <em> yellow,  constricted</em>

<em></em>

F1 generation:                           Sysy ×  Sysy              ...(from punnet square)

<em>phenotype</em><em>:        yellow,  inflated    </em>× <em> yellow,  inflated </em>

<em></em>

<em>∴ all are genotypically heterozygous, inflated, and yellow</em>

Consider the terms egg, sperm, and sporophyte. Which term links egg and sperm directly to sporophyte?
NARA [144]

Answer:

Explanation:

La fecundación es el proceso por el cual dos gametos (masculino y femenino) se fusionan durante la reproducción sexual para crear un cigoto con un genoma derivado de ambos progenitores. Los dos fines principales de la fecundación son la combinación de genes derivados de ambos progenitores y la generación de un cigoto.

En el caso de las plantas con semillas pros, hay que diferenciar el fenómeno de la fecundación propiamente dicho (unión íntima de dos células sexuales hasta confundirse sus núcleos respectivos y, en mayor o menor grado, sus citoplasmas),1​ del proceso biológico que lo antecede: la polinización, en el que los granos de polen, desarrollados en las tecas que contiene cada antera de un estambre (hoja reproductora masculina), son transportados por el viento o los insectos a los estigmas, donde germinan emitiendo un tubo polínico que crece hacia el ovario. En este caso no se trata de gametos, sino de esporas, pues cada grano de polen contiene dos gametos o células reproductoras masculinas
