Question

Two organisms each with the genotypes TtGg mate. The chance of producing an offspring that has the dominant phenotype for height (T) and the recessive phenotype for color (g) is

Answer 1

The probability is 3/16, or 18.75%.

Answer 2

Answer:

Chance of producing an offspring that has the dominant phenotype for height (T) and the recessive phenotype for color (g) is $\frac{3}{16}$

Explanation:

The punnet representing the cross between two  organism having genotype TtGg is as follows -

TG         Tg         tG          tg

TG TTGG TTGg TtGG TtGg

Tg TTGg TTgg TtGg Ttgg

tG TtGG TtGg ttGG ttGg

tg TtGg Ttgg ttGg  ttgg

The dominant phenotype of height will have genotype either Tt or TT

The recessive phenotype for color will have genotype gg

Thus, among all the offspring the required offspring are - Ttgg or TTgg which are three in numbers.

Thus, chance of producing an offspring that has the dominant phenotype for height (T) and the recessive phenotype for color (g) is $\frac{3}{16}$
