What would the phenotypes and the phenotypic ratio be if the F1 individuals produced in a male blue tailed gecko being crossed with a female green tailed gecko, and all 28 of the off spring having green tails, were mated brother sister?

In a cross between BbTtSS and BBttSs, what is the probability of offspring being BBTtSS? Be specific on the answer

A fish with red eyes and yellow scales is crossed to a pure-breeding fish with brown eyes and orange scales, resulting in offspring having red eyes and yellow scales (50%) or brown eyes and yellow scales (50%). You cross the red eye/yellow scale offspring together, and the resulting offspring are as follows. How are these traits likely inherited Number of offspring 676-yellow/red 224-red/orange 224-brown/yellow 76-brown/orange

Feather colour in parakeets is controlled by two genes. Blue colour (B) is dominant over absence of colour (b). Yellow colour (Y) is dominant over absence of colour (y). When a B allele and a Y allele are present, a green parakeet is produced.The probability of obtaining a female or male parakeet is the same as for humans. A green parakeet crossed with a white parakeet produced offspring with four different colour patterns.What is the genotype of the green parakeet?  Answer

The black fur allele (Y) is dominant to organge (y). The dominant allele is embryonic lethal in homozygotes. two heterozygotes are crossed together. What would be the expected phenotypic and genotypic ratios of it's pups?

If a drone with short wings and black eyes was mated to a queen that is heterozygous for both genes, what are the predicted genotypic and phenotypic frequencies of the offspring, (assume an equal number of male and female offspring are produced)?

Explain why all of the offspring in the F2 generation aredextral even though some of them are dd.

pure-breeding yellow (Y) canaries crossed with pure breeding blue (y)  canaries make green cancaries. identify the genotypic and phenotypic ratios when you cross a  green with a blue.  what type of inheritence pattern is this?

In a monohybrid cross and simple dominance, what is the probability of the dominant phenotype being expressed in the offspring? ½ 1:2:1 34 14 1:3:1

What are the chances of getting a turkey with a red wattle, if red is dominant to blue, when you cross 2 heterozygous (RrxRr) turkeys?
