Answer:

1000 sperm per second

Explanation:

Spermatogenesis is the process through which sperms are produced, testicles constantly produce sperms in the male body but the whole process takes almost 64 days normally.

For a man of age 25 the normal range of production of sperm per second is 1000. However, at the end of the cycle of sperm production that is after 64 days, 8 billion sperms are regenerated.

Rzqust [24]

Answer:

a monocot

Explanation:

Monocotiledoneas are plants that develop from a seedling with a single cotyledon. That is why we can say that maize is a monocotyledon.

Monocotyledons and dicotyledons are two classes of vegetables that belong to the angiosperm plants (plants with seeds contained within the fruits) and also phanerogams (flowering plants), currently classified as magnoliophytes, gathering approximately 230 thousand species. Monocotyledons are plants that have only one cotyledon in the seed. Cotyledons are the initial leaves of plant embryos.

A geneticist is studying two traits in the fruit fly - eye color and wing shape. They perform a dihybrid cross. If the genes for
Len [333]

Answer:

3/16

Explanation:

<u>According to Mendel's law of independent assortment of genes, when a dihybrid cross involves two genes that assort independently and one of the parents is dominant for the two genes and the other is recessive, the phenotypic ratio of the offspring at F2 would be 9:3:3:1</u>. The proportion of the offspring with the dominant parental traits would be 9/16, those with the recessive parental traits would be 1/16, while those with mixed traits would be 3/16 each.

Assuming the eye color is represented by E and the wing shape is represented by W. At F2

     EeWw    x    EeWw

E_W_ - 9/16 (dominant for both eye color and wing shape)

E_ww - 3/16 (dominant for eye color and recessive for wing shape)

eeW_ - 3/16 (recessive for eye color and dominant for wing shape)

eeww - 1/16 (recessive for both eye color and wing shape)

<em>Hence, the proportion of the offspring with dominant phenotype for eye color and recessive phenotype for wing shape would be </em><em>3/16.</em>
