Count the total number of boxes in your Punnett Square. This gives you the total number of predicted offspring. Divide the (number of occurrences of the phenotype) by (the total number of offspring). Multiply the number from step 4 by 100 to get your percent.

What is the probability that an offspring will have the same phenotype as the parents?

One Homozygous Parent

Above if the homozygous parent has two dominant alleles then all of the offspring will have the same phenotype of the dominant trait. In other words there is a 100% probability that an offspring of such a pairing will exhibit the dominant phenotype.

What is the proportion of genotype AABbCC in resulting generation by selfing a plant having the genotype AABbCC?

1:2:1.

What will be the frequency of offspring with genotype AaBbCc in a Trihybrid test cross?

Explanation: Genotype AABBCC can produce only one type of gamete i.e. ABC. … According to the question a perfect heterozygous cross will occur only when abc gamete from AaBbCc parent fertilises with ABC gamete from AABBCC parent. Thus the frequency for this = 1/8X1 = 1/8.

How do you find the Trihybrid cross?

What is the genotype of Trihybrid cross?

a trihybrid cross yields a phenotypic ratio of 27:9:9:9:3:3:3:1. This reflects the phenotypes generated by the 64 genotypic combinations resulting from 8 different male gametes fertilizing 8 different female gametes.

What is the genotype of the man?

The sex genotype for a human male is denoted as XY.

What phenotypic ratio would you expect in a test cross of an individual heterozygous at two loci of interest?

Correct. A dihybrid cross between individuals heterozygous for both traits will result in a 9:3:3:1 phenotypic ratio.

Which of the following statements describes the major reason that the individual with the genotype AaBbCCDdEE can make many kinds of gametes?

Which of the following statements describes the major reason that the individual with the genotype AaBbCCDdEE can make many kinds of gametes? Abnormal chromosomes are frequently found in malignant tumors. Errors such as translocations may place a gene in close proximity to different control regions.

How many phenotypes are produced from test cross?

These four genotypes can produce one two two and four different gametes respectively (Table 3). Moreover in combination with the single gamete from the “tester” parent these gametes will produce one two two or four progeny phenotypes.

How many types of phenotypes are produced from the selfing of a plant with genotype AaBbCc?

Selfing is the process of fertilization with polar or male gametes of the same individual. AABbCC will produce two type of gametes ABC and AbC. Thus in F generation three genotypes will be obtained.

How many genotypes and phenotypes are produced in a test cross of Aabbccddee?

So there will be 243 genotypes and 32 phenotypes in F2 generation.

When F1 individual is crossed with recessive parent the cross is called?

When a progeny of F1 is crossed with the homozygous recessive parent it is called testcross.

What is the genotypic ratio of progeny obtained from a cross AA BB AA?

A parent with genotype AaBB has two types of gametes AB and aB and a parent with genotype aaBB has only one type of gamete which is aB. When a cross happens between these parents the genotype of offspring will be AaBB and aaBB in the ratio of 1:1. The cross is purely based on the mendelian principle.

How do you calculate the number of phenotypes?

There is a range of phenotypes but most of the offspring are similar in color to the parents. If n = the number of gene pairs then (2n + 1) will determine the total number of categories of phenotypes.

How do you determine the number of genotypes?

How many different gamete genotypes can each parent produce?

four different combinations

Since each parent has four different combinations of alleles in the gametes there are sixteen possible combinations for this cross.

See also what things did the han dynasty standardize?

How many types of gametes are found in AaBbCc and AaBbCc?

So the correct answer is ‘Four‘.

How many types of gametes are found in?

In certain organisms like humans there are two morphologically distinct types of gametes: (1) the male gamete (i.e. sperm cell) and (2) the female gamete (i.e. ovum). The male gamete is smaller in size and motile whereas the female gamete is several times bigger and non-motile.

How many different types of gametes are produced by the F1 offspring?

Answer: f1 offspring produces two types of gametes since it is heterozygous.

How many unique gametes could be produced by an individual with the genotype AABbCC?
