Marfan syndrome is a dominant trait. A cross between a homozygous dominant and a heterozygote would produce what phenotypic rati
umka2103 [35]

Answer:

The correct answer is- 4:0

Explanation:

Marfan syndrome is a genetic problem which affects the connective tissue in the body. The trait for this disease is autosomal dominant which means even one abnormal copy of this gene in the offspring or individual is sufficient to cause this syndrome.

Let S is the allele that is dominant for this syndrome and s is recessive. So if a cross between homozygous dominant(SS) and heterozygous individual (Ss) occurs than all the offspring would have this syndrome.  

                                   S      s

                              S  SS   Ss

                              S  SS   Ss

Therefore all 4 offspring would have at least one dominant allele which is sufficient to cause this syndrome. So the phenotype ratio would be 4:0.

Does female sperm and male sperm look different
nikdorinn [45]

Answer:

the Y chromosome is smaller than the X chromosome.

Explanation:

The male has an X and Y sex chromosome which is an exception to the general rule that homologous chromosomes are identical as the Y chromosome is smaller thus enabling it to swim faster than the X chromosome. The Y chromosome also has a longer lifespan compared to the X chromosome. The male genotypes is XY. Males are heterogametic as they produce two types of gametes, one carrying the X and the other carrying a Y chromosome.
