Thutmose III ("the Napoleon of Egypt": reign 1479–1425 BC) expanded Egypt's army and wielded it with great success to consolidate the empire at the peak of Egypt's power and wealth during the reign of his successors Amunhotep II (reign 1427–1401 BC or 1427–1397 BC), Thutmose IV (reign 1401 – 1391 BC or 1397 – 1388 BC)

Complete the Punnett square for the following cross-pollination and give the genotypic and phenotypic ratios: for white (WW) and

hammer [34]

Answer:

Phenotypic ratio= 1:1

Genotypic ratio = 1:1

Explanation:

This is a monohybrid cross involving a single gene that specifies a color phenotype.

According to the question, WW, which is homozygous dominant i.e same allele is white while ww, which is homozygous recessive is black.

Hence a genotype Ww will possess a white phenotype since the W allele will mask the expression of w.

In a cross between a female and male with a a Genotype Ww and ww respectively. The parents alleles will be separated into gametes according to Mendel's law of segregation. (See attached image).

Ww will produce gametes W and w

ww will produce gametes w and w

The four possible offsprings will have Ww (2) and ww (2) genotypes. Hence two of them will be white while two will be black.

Hence, the phenotypic ratio will be 1:1 while the genotypic ratio will also be 1 Ww: 1 ww
